摘　　要：随着电力电子技术的不断发展,功率器件的不断更新,控制技术的不断完善,越来越多的场合采用变频调速来有效地改善系统运行效率。文章探讨了新型的双PWM变频器对整流侧和逆变侧均采用PWM技术,其网侧电流接近正弦波、网侧功率因数可控、电能双向传输、较快的动态控制响应,可实现电动机的四象限运行。With the continuous development of power electronic technology, continuous update of power device, and continuous improvement of control technology, more and more occasions use variable frequency speed regulation to effectively improve the running efficiency of the system. This paper discusses the dual PWM converter model which adopt PWM technology on the rectifier side and the inverter side, the network side current is close to sine wave and power factor is controllable, energy is transferred in two-way, dynamic control response is fast, and four quadrant operation of the motor can be realized.
