Analysis of Harmonics in Rectification Circuit and Correction of Single-stage Power Factor 整流电路的谐波分析及单级功率因数校正
A new circuit of separable three-phase PFC ( power factor correction ) was proposed. One-cycle control strategy was applied to achieve unity power factor in three-phase rectifier. 提出了一种新型分离式三相PFC(功率因数校正)系统结构,并应用单周期控制技术实现了三相整流器的单位功率因数。
Those PSS circuits which have good overall performances are applied to single-phase PWM Active Power Factor Correction ( APFC ) circuit which is high-frequency PWM technology and also operated in CCM. 本文还将那些具有综合性能特性较佳的PSS电路也应用到高频PWM技术的AC-DC整流器的有源功率因数校正器(ActivePowerFactorCorrection,APFC)上。
