中文摘要: 在大容量的PWM整流电路中引入了多重化方法,探讨了多重化PWM整流器中较为核心的载波移相技术,并对单相PWM整流器的叠加方式进行了分析和研究.仿真结果证明:通过载波移相技术可以在较低开关频率条件下达到较高开关频率的等效效果,从而有效地消除低次谐波.
Abstract:The method of multiplification is introduced in large capacity PWM rectifying device,carrier-shifted technology that is most important in multiple PWM rectifying device is mainly discussed;the dual-stacking method on single-phase rectifier is researched.Simulation results prove that multiple PWM rectifiers can achieve equivalent higher switch frequency under the lower switch frequency condition,and can also eliminate lower harmonic effect.
