本文主要内容是关于单相PWM逆变器的输出电压波形控制技术。好的输出波形 包含两个方面的要求：稳态精度高和动态响应快。本文围绕这两点，分析了重复控制 技术和双环控制技术，并进行了一系列仿真和实验。 (The output waveform correction technology of single-phase PWM inverter is studied in this dissertation.High quality waveform has two characteristics.It has not only nice static characteristic but also well dynamic response.Aiming at these characteristics, repetitive control technology and dual-loop control technology is analyzed.Both these control scheme are verified by simulation and experiment. )
