三相四桥臂逆变器的工作原理与控制方式

Operating Principle and Control Method of Three-phase Four Bridge Legs Inverter

本文介绍了三相四桥臂逆变器的工作原理和控制方式。这是一种新型的三相四线逆变器,用附加的一个桥臂形成中性点,以对任何不同种类的负载提供对称的三相电压。

Operating principle and control method of three-phase four bridge legs inverter is presented in this paper.This is a nevel three-phase four-wire inverter.The inverter eliminates the neutral forming transformer by adding a bridge leg to iorm neutral point to provide symmetry voltages to any kinds of three phase loads.
