摘要
本文针对电力系统中整流负载存在谐波电流大和功率因数低的问题，提出了一种改善系统谐波和功率因数的PWM控制方法，并研究了相应的控制策略及控制系统。通过PWM控制，可以提高负载系统的功率因数，降低系统电流谐波含量，研究结果表明该方法是可行的。
A PWM control strategy with low harmonic current and high power factor is suggested in this paper to solve the problems of high harmonic current and low power factor caused by rectifier in power system, and the correspondence control calculation and control system are studied. Used by PWM control,power factor can be promised and harmonic current can be decreased, the research results proved that the suggested method is valid.
