摘　　要：文中分析了多重化技术在整流电路,逆变电路,以及PWM电路中的原理及应用。采用串联多重化的方法设计了移相100串联6重联结电路来消除低次谐波,结果表明了移相100串联6重联结电路可以消除36k±1次以外的谐波,并且使最低次数提高,幅值减小,总体谐波含量减少,且具有减少对电网谐波污染的优点。最后,给出了仿真和系统实验波形。This article analysis principle of the multiple of the bunch connection and the parallel connection. In the end, we design the shift 100 bunch connection and 6 posture connection Circuit to reduce the lower-order harmonic. According to the analysis, the circuit can eliminate the harmonics other than n class n=36k±1 and hardly pollutes the electricity grid ,also make the lowest harmonics boost and the amplitude reduce .The simulation fuffiUed by PSPtCE and the experimental waveforms are also given.
