摘　　要：谐波问题关系到供电系统的供电安全和质量.采用功率因数校正技术,可以减小谐波污染,提高效率.对四种功率因数校正电路进行了比较,包括无源和有源功率因数校正电路,通过Simulink仿真软件给出每种电路的仿真结果.结果表明,无源功率因数校正电路具有较大的位移角和位移因数,功率因数校正效果一般;而有源功率因数校正电路只有极小的位移角和位移因数,基本上不产生失真.无源功率因数校正技术消除谐波结构简单、设计成本低,但功率因数校正效果差;有源功率因数校正技术结构复杂,设计成本较高,但功率因数校正效果好,能够消除谐波和减小无功功率.The harmonic problem is related to the safety and quality of power supply system.Using power factor correction technology can reduce harmonic pollution and improve efficiency.In this paper,four kinds of power factor correction circuits were compared,including passive and active power factor correction circuits.The simulation results of each circuit were given by Simulink of simulation software.The results show that the passive power factor correction circuit has large displacement angle and displacement factor,and the power factor correction effect is general.However,the active power factor correction circuit only has a very small displacement angle and displacement factor,which basically does not produce distortion.Passive Power Factor Correction(PPFC)technology has the advantages of simple structure and low design cost to eliminate harmonics,but it has poor performance in power factor correction.Active Power Factor Correction(APFC)technology has complex structure,high design cost,good power factor correction effect,can eliminate harmonics and reduce reactive power.
