| 摘 要： | PWM调制技术已广泛应用于电力电子技术中,但PWM调制信号含有大量的高次谐波,成为产生EMI的主要原因之一。开关功率变换器中应用随机PWM调制技术能有效地减小传导EMI,改善系统电磁兼容性。常用的随机PWM调制技术有随机周期调制和随机脉冲位置调制,通过对两种方法的分析与实验,结果表明随机周期调制技术具有相对更好地减小EMI的作用。

| Abstract: | Though PWM modulation technology has already been used in power converter abroad,it becomes a main reason which can produces EMI because PWM modulation signal contains abundant high harmonic.It can reduce conduct EMI effectively and improve EMC of system to use randomized PWM modulation.There are two common randomized modulation which is randomized period modulation and randomized pulse-position modulation.Analysis and experimentation indicates that randomized period modulation has better effect to reduce EMI than randomized pulse-position modulation. |
