摘要

提出了两种强制换相PWM(脉宽调制)变换器的遗传结构，即电压源逆变器和电流源逆变器，作为先进的无功补偿器。本文提出了一种结合了这两种结构特点的新结构，并对其进行了分析。它由处理低开关频率的高功率的PWM电流源逆变器和处理高开关频率的低功率的PWM电压源谐波滤波器组成。结果是开关损耗和谐波畸变同时被最小化。

A new converter topology for advanced static VAr compensation in high power applications

Two genetic configurations of forced commutated PWM (pulse-width-modulated) converters, i.e., voltage source inverters and current source inverters, have been proposed as advanced reactive power compensators. A new configuration combining the features of the two generic ones is proposed and analyzed in the present work. It is composed of a PWM current source inverter handling high power with very low switching frequency, and a PWM voltage source harmonic filter handling low power with a much higher switching frequency. The result is that switching losses and harmonic distortions are minimized simultaneously.<>
