发射机系统中桥堆整流的工作原理及检测

Working Principle and Detection of Bridge Rectification in Transmitter System

桥堆作为一种功率元器件,应用非常广泛。应用于各种电源设备。其内部主要是由四个二极管组成的桥路来实现把输入的交流电压转化为输出的直流电压。桥堆作为发射机系统的电源部分,桥堆的工作稳定与好坏,直接影响发射机的稳定性,这就需要我们对其内部结构了解,并能快速的通过万用表测试桥堆的好坏。

As a kind of power component,a bridge rectifier is widely used and applied to various power supply equipment.Its interior is mainly composed of four diodes to realize the conversion of the input AC voltage to the output DC voltage.As the power part of the transmitter system,the stability of the bridge rectifiers directly affects the stability of the transmitter.So it is needed to understand the internal structure of the bridge heap and can quickly test the bridge heap through the multimeter.
