How to choose a rectifier bridge?

The role of rectifier bridge: the rectifier function of bridge rectifier is through the diode's single conduction principle to complete the work, to achieve the conversion of alternating current to direct current.

Rectifier bridge is divided into full bridge and half bridge. The full bridge is connected to the bridge rectifier circuit of four diodes packaged together. Half bridge is the four diodes bridge rectifier half package together, with two half bridge can form a bridge rectifier circuit, a half bridge can also form a transformer with the center tap full wave rectifier circuit. Select rectifier bridge to consider the forward current and reverse voltage. As a rectifier component, the diode should be selected according to different rectifier mode and load size. If you choose improperly, it will not work properly, or even burn the tube.

We can choose from the following aspects:

· There are many varieties of rectifier bridges, such as flat, round, square, bench-shaped (divided into direct plug and SMD), etc.

· Chip with GPP and O / J of the difference

· Rectifier current from 0.5A to 100A, reverse peak voltage from 50V to 1600V

如何选择整流桥？

整流桥的作用：整流桥的整流作用是通过二极管的单向导通原理来完成工作的，得以实现交流电转换为直流电

整流桥分为全桥和半桥。全桥是将连接好的桥式整流电路的四个二极管封装在一起。半桥是将四个二极管桥式整流的一半封装在一起，用两个半桥可以组成一个桥式整流电路，一个半桥也可以组成变压器带中心抽头的全波整流电路，选择整流桥要考虑正向电流和反向电压。二极管作为整流元件，要根据不同的整流方式和负载大小加以选择。如果选择不当，会导致不能正常工作，甚至烧毁管子

我们可以从以下方面选择：

· 整流桥的品种有很多，比如扁形、圆形、方形、板凳形（分直插与贴片）等

· 芯片有GPP和O/J之分

· 整流电流从0.5A到100A，反向峰值电压从50V到1600V
