What is the rectifier bridge stack? As we all know, bridge stack is a kind of diode. So, what is rectifier bridge stack?

1、 What is rectifier bridge stack

The so-called rectifier bridge stack is composed of four diodes with four lead pins. The connection point of the negative electrodes of the two diodes is the "positive electrode" of the DC output end of the full bridge. The connection point of the positive electrodes of the two diodes is the "negative electrode" of the DC output end of the full bridge. There are two kinds of bridge stacks: Half Bridge and full bridge, and the half bridge has two kinds of positive half bridge and negative half bridge.

2、 Rectifier half bridge and rectifier full bridge

The half bridge is composed of two diodes and three lead pins. The pins on both sides of the positive half bridge are the positive poles of the two diodes, i.e. the AC input end; The middle pin is the negative pole of the two diodes, i.e. "positive pole" of the DC output terminal. The negative electrodes of the two diodes on the pins on both sides of the negative half bridge, i.e. the AC input terminal; The middle pin is the positive pole of the two diodes, i.e. "negative pole" of the DC output terminal. A positive half bridge and a negative half bridge can form a full bridge.

3、 Packaging form

There are four kinds of rectifier bridge packages: square bridge, flat bridge, round bridge and SMD Mini bridge; The square bridge is mainly packaged with (BR3, BR6, BR8, gbpc, kbpc, kbpc-w, gbpc-w, mt-35 (three-phase bridge)); The flat bridge is mainly packaged with (kbp, KBL, kbu, kbj, GBU, GBJ, d3k); The round bridge is mainly packaged with (WOB, WOM, Rb-1); The chip Mini bridge is mainly packaged (BDS, MBS, MBF, ABS).

4、 Basic principle of rectifier bridge stack

Half bridge is to seal half of two diode bridge rectifiers together. Two half bridges can form a bridge rectifying circuit, and one half bridge can also form a full wave rectifying circuit with center tap of transformer.
