英文摘要：

A novel high power factor rectifier was proposed.A passive lossless snubber was employed in main circuit to realize zero-current turn-on and zero-voltage turn-off for the main switch.The IR1150 chip based on one cycle control,which was intended for boost converters for power factor correction（PFC） operating at a fixed frequency in continuous conduction mode（CCM）,was used as its control core.The fundamental principle of power factor correction based on one cycle control and passive lossless snubber for the proposed rectifier was introduced.Its sections such as boost inductor,passive lossless snubber,EMI filter and noise suppression,and so on,were analyzed and designed respectively.The results show that the boost high power factor rectifier is rational and reliable.It does not need multipliers,AC input voltage sensing and fixed ramp oscillator,and the use of the IR1150 in control circuit makes the PFC circuit design easy and the volume of the rectifier small.Its power factor can reach 0.992.
