Generally speaking, we call the components directly plugged into the circuit board as Dip components. The corresponding components are SMD components. There are some internal bridge rectifiers with large power and capacity that require additional heat sinks and special installation places. Therefore, the Dip bridge rectifier refers to the bridge rectifier that is directly plugged into the circuit board. Generally, the power is not very large. Most of the common ones are <20A, and a heat sink can be added to the circuit board.

Common classifications of bridge rectifiers are generally directly classified by their withstand voltage and allowable current.

Bridge rectifiers are generally used in circuits that require AC (pulse) to DC conversion. Most electrical appliances are used. They are generally used in switching power supplies or power circuits of electrical appliance, low-power switching power supplies, chargers, power adapters, LED light rectifiers, electric fans, TV sets, indoor air conditioners and other related electrical products.

GBU1010 GBU bridge rectifier is a rectifier device composed of two or four diodes.

The bridge stack has three types of half bridge，full bridge, and three-phase bridge, and there are two types of positive half bridge and negative half bridge.
The full bridge consists of four diodes with four lead-out pins.

The connection point of the cathodes of the two diodes is the "positive" of the full-bridge DC output terminal, and the connection point of the anodes of the two diodes is the "cathode" of the full-bridge DC output.

The half bridge is composed of two diodes with three lead-out pins.
The pins on both sides of the positive half-bridge are the anodes of the two diodes, that is, the AC input terminal; the middle pins are the cathodes of the two diodes, that is, the "positive" of the DC output terminal.
The negative poles of the two diodes on the pins on both sides of the negative half bridge are the AC input terminals; the middle pin is the anode of the two diodes, that is, the "negative" of the DC output terminal.

A positive half bridge and a negative half bridge can form a full bridge.

WEET Tells How to Measure the Quality of the Bridge Rectifier

Take three-phase rectifier bridge as an example. With a digital meter, it is normal if there is a voltage drop of about 700mV during forward measurement. If the voltage drop is small, it will be broken down, and if the voltage drop is too large, it will be blown. No pressure drop is normal. Multimeters are also called multiplex meters, multimeters, three-meters, multi-meters, etc. They are indispensable measuring instruments in power electronics and other sectors. They generally measure voltage, current, and resistance as their main purpose.

The three-phase bridge rectifier is composed of 6 diodes in series and parallel, and each diode can be measured separately according to the method of measuring a single diode.

According to the display mode, multimeters are divided into pointer multimeters and digital multimeters. It is a multi-function, multi-range measuring instrument. Generally, a multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc. Some can also measure AC current, capacitance, inductance and semiconductor parameters (such as β), etc.

Measurement method of Bridge Rectifier：

The measurement method of the rectifier bridge stack is to use a multimeter to measure.

Measurement method: when normal, the forward and reverse resistances of the two AC input terminals ("~") of the full bridge are both infinite; the forward resistance of the "+""-" input terminal is infinite, and the reverse resistance (connected with red pen) "+", black pen connected to "-" end) is about 20K. Assuming to check with a digital universal meter (diode) file, the red pen is connected to "-', the black test pen is connected to "+" is 0.8; two "~" are connected are about 0.4, the red pen is connected to "+", the black pen is connected to the other three pins It must be infinite, otherwise it is a damaged rectifier.

The rectifier full bridge is composed of four diodes with four lead-out pins: the connection point of the negative poles of the two diodes is the "positive" of the DC output end of the full bridge, and the connection point of the anodes of the two diodes is the "negative" of the DC output end of the full bridge. The half bridge is composed of two diodes with three lead-out pins.

The pins on both sides of the positive half-bridge are the anodes of the two diodes, that is, the AC input terminal; the middle pins are the cathodes of the two diodes, that is, the "positive" of the DC output terminal. The negative poles of the two diodes on the pins on both sides of the negative half bridge are the AC input terminals; the middle pin is the positive poles of the two diodes, that is, the "negative poles" of the DC output terminals.

1. The basic principle of the rectifier bridge stack: The rectifier bridge stack product is made of four rectifier silicon chips for bridge connection and externally packaged with insulating plastic. The high-power rectifier bridge is encapsulated with a zinc metal shell outside the insulating layer to enhance heat dissipation. There are many types of rectifier bridges: flat, round, square, bench-shaped (in-line and patch), etc. There are GPP and O/J structures.

The maximum rectified current ranges from 0.5A to 100A, and the maximum reverse peak voltage ranges from 50V to 1600V. The half bridge is to seal the half of the two diode bridge rectifiers together. Two half bridges can form a bridge rectifier circuit, and a half bridge can also form a full wave rectifier circuit with a center tap of the transformer.

The full bridge is composed of 4 rectifier diodes connected in the form of a bridge full-wave rectifier circuit and packaged as a whole. The forward current of the full bridge has various specifications such as 0.5A, 1A, 1.5A, 2A, 2.5A, 3A, 5A, 10A, 20A, 35A, 50A, etc. The withstand voltage (the highest reverse voltage) is 25V, 50V, 100V, 200V, 300V, 400V, 500V, 600V, 800V, 1000V and other specifications.

2. Package form There are four types of rectifier bridge packages: square bridge, flat bridge, round bridge, and patch MINI bridge. The main packages of square bridges are (BR3, BR6, BR8, GBPC, KBPC, KBPC-W, GBPC-W, MT-35 (three-phase bridge)); the main packages of flat bridges are (KBP, KBL, KBU, KBJ, GBU, GBJ, D3K); round bridges are mainly packaged (WOB, WOM, RB-1); SMD MINI bridges are mainly packaged (BDS, MBS, MBF, ABS).

How to measure the quality of bridge rectifier?

Use the diode gear of the digital multimeter or the 100 or 1000 gear of the pointer meter to measure the resistance between the two AC input terminals and the output positive terminal of the rectifier bridge. If it is open or short, the rectifier bridge is broken. The normal value should be 400 to 2000 ohms.?

It can also be measured that the resistance from the positive terminal to the input terminal should be infinite, otherwise it is broken. The resistance value from the negative terminal to the input terminal should also be 400 to 2000 to be considered normal.

If the positive and negative DC output voltages are not normal, you do not need to check the rectifier diodes, but check the power transformer, because it is less likely that several rectifier diodes will have the same fault at the same time.

When a certain group of rectifier circuits fails, check according to the fault detection methods described above. The diodes VD1 and VD3, VD2 and VD4 of the rectifier diodes in this circuit are connected in parallel with the DC circuit, and they will affect each other during on-circuit detection. Therefore, the diode should be disconnected from the circuit for accurate detection.

In each working cycle of the bridge stack, only two diodes are working at the same time. The unidirectional conduction function of the diodes converts the alternating current into a unidirectional direct current pulsating voltage. Anatomy of a commonly used low-power bridge stack will reveal that the full-wave bridge stack adopts a plastic package structure (most low-power bridge stacks use this package form).

The high-power rectifier bridge is enclosed by a zinc metal shell outside the insulating layer to enhance heat dissipation. There are many types of rectifier bridges: flat, round, square, bench-shaped (in-line and patch), etc. There are GPP and O/J structures. The maximum rectified current ranges from 0.5A to 100A, and the maximum reverse peak voltage ranges from 50V to 1600V.

How to test the bridge rectifier in a simple way?

Commonly used bridge rectifier detection methods

1, Static Test
(1) Test the rectifier circuit to find the P and N terminals of the internal DC power supply of the inverter, adjust the multimeter to resistance X10, connect the red meter to P, and the black meter to R, S, and T respectively. There should be approximately Resistance value of tens of ohms, and basically balanced.

On the contrary, connect the black meter rod to the P terminal, and the red meter rod to R, S, and T in turn, with a resistance value close to infinity. Connect the red meter stick to the N terminal and repeat the above steps, you should get the same result.

If there are the following results, it can be determined that the circuit has been abnormal, A. The resistance of the three-phase imbalance, can indicate the rectifier bridge failure. B. When the red meter rod is connected to the P terminal, the resistance is infinite, and it can be concluded that the rectifier bridge is faulty or the starting resistance is faulty.

(2) To test the inverter circuit, connect the red meter rod to the P terminal, and the black meter rod to U, V, W respectively. There should be a resistance value of several tens of ohms, and the resistance value of each phase is basically the same, and the reverse phase should be gigantic. Connect the black meter rod to the N terminal and repeat the above steps to get the same result, otherwise it can be determined that the inverter module is faulty

2, Dynamic Test
After the static test result is normal, the dynamic test can be performed, that is, power on and test the machine.

The following points must be paid attention to before and after power-on: 1. Before power-on, confirm whether the input voltage is wrong. Connecting the 380V power supply to the 220V-class inverter will cause explosions (fried capacitors, varistors, modules, etc.) . 2. Check whether each broadcast port of the inverter is properly connected, and whether the connection is loose. Abnormal connection may sometimes cause the inverter to malfunction, and in severe cases, it may explode.

3. Check the fault display content after power-on, and preliminarily determine the fault and cause.

4. If no fault is displayed, first check whether the parameters are abnormal, and after resetting the parameters, start the inverter under no-load (no motor connection), and test the U, V, and W three-phase output voltage values.

If there is a lack of phase, three-phase unbalance, etc., the module or drive board is faulty. 5. When the output voltage is normal (no lack of phase, three-phase balance), load test. When testing, it is best to test at full load.

WEET Flat Bridge Rectifiers 1000V 6A 10A 50A GBJ1010 GBU1010 GBU610 GBJ5010 Single Phase Silicon Bridge

There are four types of bridge rectifier packages: square bridge, flat bridge, round bridge, and patch MINI bridge.

Square Bridge Rectifiers main packages: BR3, BR6, BR8, GBPC, KBPC, KBPC-W, GBPC-W, MT-35 (three-phase bridge).
Flat Bridge Rectifiers main packages: KBP, KBL, KBU, KBJ, GBU, GBJ, D3K.
Round Bridge Rectifiers main packages: WOB, WOM, RB-1.
SMD MINI Bridge Rectifiers main packages: BDS, MBS, MBF, ABS.

Connect the positive poles of two diode rectifiers (set this junction point as A) to form a series branch, and connect the negative poles of the other two diode rectifiers (set this junction point as B) to form another series branch, and then connect the above two branches in parallel (set the two branches and the connection points are respectively C and D), and the formed circuit is a square bridge rectifier. Also called a single-phase bridge rectifier circuit. AC power is input from C and D terminals, DC power Output from A (positive) and B (negative) terminals.

The Bridge Rectifier is made up of four rectifier silicon chips for bridge connection, and externally packaged with insulating plastic. The high-power bridge rectifier is encapsulated by zinc metal shell outside the insulating layer to enhance heat dissipation. There are many varieties of bridge rectifiers: flat, round, square, bench-shaped (in-line and patch), etc. The maximum rectified current ranges from 0.5A to 100A, and the maximum reverse peak voltage ranges from 50V to 1600V.

The Bridge Rectifier is generally used in full-wave rectifier circuits, and it is divided into full bridge and half bridge.

The half bridge is to seal the half of the two diode bridge rectifiers together. Two half bridges can form a bridge rectifier circuit, and a half bridge can also form a full wave rectifier circuit with a center tap of a transformer. The full bridge is composed of 4 diode rectifiers connected in the form of a bridge full-wave rectifier circuit and packaged as a whole.

The forward current of the full bridge has various specifications such as 0.5A, 1A, 1.5A, 2A, 2.5A, 3A, 5A, 10A, 20A, 35A, 50A, etc. The withstand voltage (the highest reverse voltage) is 25V, 50V, 100V, 200V, 300V, 400V, 500V, 600V, 800V, 1000V and other specifications.

Schottky diode, also known as Schottky barrier diode (SBD), is a low-power, ultra-high-speed semiconductor device. The most notable feature is that the reverse recovery time is extremely short (can be as small as a few nanoseconds), and the forward voltage drop is only about 0.4V. It is mostly used as high-frequency, low-voltage, high-current rectifier diodes, freewheeling diodes, protection diodes, and also useful as rectifier diodes and small signal detector diodes in circuits such as microwave communications. It is more common in communication power supplies, inverters, etc.

A typical application is in the switching circuit of a bipolar transistor BJT. By connecting a Schottky diode to the BJT to clamp, the transistor is actually close to the off state when it is on, thereby increasing the switching speed of the transistor. This method is a technique used in the TTL internal circuits of typical digital ICs such as 74LS, 74ALS, and 74AS.

The biggest feature of Schottky diodes is that the forward voltage drop VF is relatively small. At the same current, its forward voltage drop is much smaller. In addition, its recovery time is short. It also has some disadvantages: the withstand voltage is relatively low, and the leakage current is slightly larger. It must be fully considered when selecting.

WEET Tells How to Quickly Grasp the Necessary Electronic Components for IoT Design

At the time when the Internet of Things (IoT) is booming, a variety of novel electronic product designs are sprouting, and equipment developers are making every effort to speed up product development and time to market in order to seize market share as soon as possible. With the increasingly fierce competition in the market, understanding how to quickly grasp the necessary electronic components for IoT design, as well as the important evaluation indicators and techniques for selecting relevant components, is of vital importance to promoting product launches.

Package:
The packaging of electronic components refers to how the parts are mounted on the circuit board. Many parts are either soldered on a printed circuit board (PCB), through a through-hole method, or using surface mount technology.

Basic Electronic Components:
The simplest components are discrete passive components. These parts have only a single function, such as providing resistance, capacitance, inductance, or adding voltage or current control. Most discrete components have only two to three pins.

Capacitor:
Capacitors store charge. Capacitors are mostly used for frequency filtering. Its unit is Faraday, F. Can use through hole or SMT package. The electrolytic capacitor has polarity and must be installed correctly, otherwise the capacitor may be damaged. When purchasing a capacitor, you must declare the polarity, type of dielectric (such as ceramic, plastic, paper, etc.), rated voltage and capacitance.

Diode Rectifier:
The diode rectifier can allow or block the flow of current in the circuit according to the voltage across it. Current is only passed when the anode voltage is higher than the cathode, and usually needs to be at least 0.7 volts higher. The diode is like a one-way valve, preventing the voltage from going in the wrong direction.

It is used for current conversion from AC to DC to prevent out-of-range input voltage. Zener diode is a special type of diode used as a voltage regulator. Schottky diodes have lower forward voltage drop (in the range of 0.15 to 0.45V) and faster turn-on time.

Transistor:
The transistor is a multifunctional circuit element. This three-pin device can be used as a voltage or current dependent switch, or as an amplifier or stabilizer depending on the circuit. There are two main technologies, bipolar junction (BJT) and field effect (FET). The pin terminals of these two types of transistors are different. BJT transistors are divided into two types according to the polarity of the components, NPN and PNP. FET transistors also have many classifications based on n-channel and p-channel.

WEET Forward: China Intends to Fully Support the Semiconductor Industry

China is vigorously supporting the development of its own semiconductor industry, is planning to formulate a comprehensive set of new policies to develop its own semiconductor industry, and to give this task a high priority "just as it did when it made an atomic bomb.

Beijing is preparing to provide extensive support for "third-generation semiconductors" within five years to 2025. A series of measures have been added to the draft of China's 14th Five-Year Plan to strengthen research, education and financing in this industry. Compared with traditional silicon materials, the third-generation semiconductors are based on broadband semiconductor materials such as gallium nitride, silicon carbide, and zinc selenide, which are more suitable for manufacturing high-frequency and high-power devices with high temperature resistance, high voltage resistance, and high current resistance.

China is about to formulate its next five-year plan, which includes efforts to expand domestic consumption and manufacture key technology products domestically. China has pledged to invest approximately US$1.4 trillion in technologies ranging from wireless networks to artificial intelligence by 2025. Semiconductors are actually the basis for all aspects of China's technological ambitions.

According to China Customs statistics, my country's chip imports in 2019 were US$304 billion, a decrease of US$8 billion from the same period last year and a year-on-year decrease of 2.6%. Relevant data released by the State Council show that China's chip self-sufficiency rate in 2019 is only about 30%. Recently, the State Council issued the "Several Policies to Promote the High-quality Development of the Integrated Circuit Industry and Software Industry in the New Era", stressing that the integrated circuit industry and software industry are the core of the information industry and are the key force leading a new round of technological revolution and industrial transformation.

For the core industry of chips, which is "stuck-necked," it must have the initiative and can no longer be controlled by others. Third-generation semiconductors are often used in the 5G field. China remains a leader in 5G technology and has advanced development in fields such as communications, artificial intelligence, and cloud services. These high-tech applications will promote the development of third-generation semiconductors.
