摘要
介绍了一种可连续补偿的动态电压恢复器(dynamic voltage restorer,简称DVR)的主电路结构、工作模式及工作原理。针对传统DVR不能连续补偿电网电压跌落的问题,提出了基于现代电力电子技术的PWM装置来提供逆变器直流侧电压,将能量从电源传给DVR,从而实现电压跌落的持续补偿,同时该装置对谐波干扰也能进行有效的抑制。
The main circuit structure, operation pattern and working principle of a dynamic voltage restorer (DVR) with uninterrupted compensation are introduced. The PWM device based on modern power electronic technology is proposed to solve the continuous voltage drops. It can transmit the energy to DVR from power source, and can be effective to restrain the various voltage disturbance.
