How to distinguish the quality of bridge piles?

The function of the bridge stack is to convert alternating current into direct current, also called rectifier stack. The bridge stack is an electronic component composed of multiple diodes inside.

 The main function is to rectify and adjust the current direction. It is better to use a bridge stack for rectification. First of all, it is very convenient, and the four tubes inside are generally selected and matched, so their performance is relatively close. In addition, for high-power rectification, heat sinks can be installed on the bridge stack. , to make the performance more stable at work. Of course, different bridge stacks should be selected for different use occasions, not just whether the withstand voltage is enough, such as high frequency characteristics.  

 The rectifier bridge stack product is made of four rectifier silicon chips for bridge connection, which are packaged with insulating plastic material. The high-power rectifier bridge is added with zinc metal outside the insulating layer. Shell encapsulation for enhanced heat dissipation. There are many varieties of rectifier bridges: flat, round, square, bench-shaped (in-line and patch), etc., and there are GPP and O/J structures. The maximum rectified current is from 0.5A to 100A, and the maximum reverse peak voltage is from 50V to 1600V.

 Half bridge is to seal half of two diode bridge rectifiers together. Two half bridges can be used to form a bridge rectifier circuit, and one half bridge can also be formed Transformer center-tapped full-wave rectifier circuit, 

 When choosing a rectifier bridge, the rectifier circuit and working voltage should be considered. High-quality manufacturers include the G series rectifier bridge stack of Guangzhou Guoxin Electronic Technology Co., Ltd. (Wenster Electronics). Brands include ST, IR, Taiwan-based SEP, GD, etc. The rectifier bridge stack is generally used in full-wave rectifier circuits, and it is divided into full-bridge and half-bridge.  

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

 There are 3 numbers in the name of the general rectifier bridge, the first number represents the rated current, A; the last two numbers represent the rated voltage (number*100), V< /span>
