摘要
从交─直─交变频器的整流部件的现状和存在的问题分析着手，提出了采用脉宽调制（ＰＷＭ）整流器的优选方案。本文在研究ＰＷＭ整流器数学模型的基础上，介绍了几种控制方案，以及它们的原理和实现，并给出了仿真波形。最后对这几种控制方案进行了性能比较。
Started with the analysis of the problems presented in the rectifier of AC-DC-AC inverter,a optimal scheme-use PWM rectifier is proposed. The paper researches the mathematics model of the PWM recitifier.On the base,a few of the controlled schemes, their principle and achieved are introduced and the simulation waveforms are given.Finally,their properties are compared.
