Bridge rectifier type and parameters selection principles

Bridge rectifier type and parameters selection principles

1. Bridge rectifier model.

Bridge rectifier stack is generally used in the full-wave rectifier circuit, it is divided into full bridge and half bridge.

Full bridge is composed of four rectifier diodes according to the form of bridge full-wave rectifier circuit connected and packaged as one, the figure is its shape.

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

Select rectifier bridge to consider the rectifier circuit and operating voltage.

2. Bridge rectifier parameters.

Commonly used rectifier bridge parameters are extremely parameters a total of four from left to right: product model, peak reverse voltage VRRM (V), average current (A), forward voltage drop (V), package.

整流桥型号与参数选用原则

1. 整流桥型号：

整流桥堆一般用在全波整流电路中，它又分为全桥与半桥。

全桥是由4只整流二极管按桥式全波整流电路的形式连接并封装为一体构成的，图是其外形。

全桥的正向电流有0.5A、1A、1.5A、2A、2.5A、3A、5A、10A、20A、35A、50A等多种规格，耐压值（最高反向电压）有25V、50V、100V、200V、300V、400V、500V、600V、800V、1000V等多种规格。

选择整流桥要考虑整流电路和工作电压。

2. 整流桥参数：

常用的整流桥极其参数 参数共四项从左到右依次为：产品型号、峰值反压VRRM（V）、平均电流（A）、正向压降（V）、封装。
