Brief introduction of rectifier bridge diode
Rectifier bridge stack is a rectifier device composed of two or four diodes, which is divided into full bridge and half bridge, and is generally used in full wave rectifier circuits. The character symbol of pile bridge is ur.
The full bridge consists of four diodes and four lead pins. The connection point of the negative electrodes of the two diodes is the "positive electrode" of the full bridge DC output end, and the connection point of the positive electrodes of the two diodes is the "negative electrode" of the full bridge DC output end.
Composition of rectifier bridge stack diode circuit
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.
Function of rectifier bridge diode
The function of rectifier bridge is to convert alternating current into direct current. 1. Convert AC to DC first. 2. Output through capacitor voltage stabilization. After passing through the capacitor, the capacitor can be charged. The final output voltage is a signal with small fluctuation
Packaging of rectifier bridge diode
There are four kinds of rectifier bridge packages: square bridge, flat bridge, round bridge and SMD Mini Bridge
The main packages of the square bridge are: BR3, BR6, BR8, gbpc, kbpc, kbpc-w, gbpc-w and mt-35 (three-phase bridge);
The flat bridge is mainly packaged with kbp, KBL, kbu, kbj, GBU, GBJ and d3k;
The round bridge is mainly packaged with WOB, WOM and Rb-1;
SMD Mini bridge is mainly packaged with BDS, MBS, MBF and ABS.
