| 摘 要： | 本文研究了一种新的具有PWM调制功能的电流型整流器(CSR)的拓扑结构,分析了该电路的工作原理,利用改进的空间矢量脉宽调制(SVPWM)技术对其进行PWM调制.这种拓扑结构结合了传统的三相相控整流器和直流Buck斩波器的优点,实现了单位功率因数,降低了电流谐波含量,仿真及实验结果验证了采用改进控制策略的新型电流型整流器的工作性能.

| Abstract: | This paper introduces a new topology of a PWM current-source rectifier(CSR) and analyzes the function of this new PWM rectifier.This new topology,modulated by improved space vector PWM algorithm,combines the advantages of the traditional six-pulse thyristor rectifier and the DC Buck chopper,which make the new PWM rectifier operate at unity power factor,and low harmonic input current.The simulating and experimental results prove that the system works well and has good performance. |
