英文摘要：

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.
