三相PWM逆变器的主电路设计

The Design Of Main Circuit Of Three-phase PWM Inverter

随着电力电子技术的发展,逆变器的应用已深入到各个领域,一般均要求逆变器具有高质量的输出波形。逆变器输出波形质量主要包括两个方面,即稳态精度和动态性能。因此,研究既具有结构和控制简单,又具有优良动、静态性能的逆变器控制方案,一直是电力电子领域研究的热点问题。

With the development of power electronics technology, inverter is used in every field and the high quality of output waveform is required in these applications. There are two aspects for the quality of output waveform- high steady--state precision and fine transient response. So the study on simple con trol with good static and dynamic performance is a hot spot in power electronic fields.
