Modelica示例——桥式整流器

本文主要是介绍Modelica示例——桥式整流器，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

桥式整流器，英文 BRIDGE RECTIFIERS，也叫做整流桥堆，是利用二极管的单向导通性进行整流的最常用的电路，常用来将交流电转变为直流电。

参数配置：

1）电压源[sinVoltage1]

Modelica.Electrical.Analog.Sources.SineVoltage

2）四个二极管[diode2]

Modelica.Electrical.Analog.Semiconductors.Diode

正半周如下图，diode1和diode4分压，diode2和diode3断路。

负半周如下图，diode2和diode3分压，diode1和diode4断路。

红色峰值和蓝色峰值的差异为正半周或负半周中，两个二极管的分压。
