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.

WEET Measurement Method of Square, Flat, Round, Patch MINI Bridge Rectifier

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.
