摘要
研究了基于单周期控制的三相六开关高功率因数整流器,推导了三相六开关升压整流器的控制规律,设计了一种基于单周期控制技术的PFC控制器,完成了2kW三相高功率因数整流器的设计与试验。试验结果表明,该系统的功率因数可达0.991,实现了单位功率因数校正和低电流畸变。
A three-phase six-switch high power factor rectifier based on one cycle control was researched.The control laws of three-phase six-switch rectifier were deduced.A new PFC controller based on one cycle control technology was designed.The design and test of 2 kW three-phase high power factor rectifier were implemented.Experimental results proved that the rectifier＇s power factor could reach 0.991 and it could achieve low current distortion and unity power factor correction.
