Design of a Single Phase Power Factor Corrector
This paper designs a novel single phase high power factor rectifier with IR1150 as its main control chip, which main circuit uses boost topology. The fundamental principle of the proposed rectifier is introduced. The IR1150 control IC based on one cycle control is intended for boost converters for power factor correction operating at a fixed frequency in continuous conduction mode (CCM). The use of the IC will make the PFC circuit design easily, the volume of the rectifier small and the efficiency enhancing. The modules of the proposed rectifier such as current loop and over-current protection, voltage loop and over-voltage protection, soft start, and so on, are analyzed and designed respectively in detail. Experimental results of the designed 600W prototype prove that the boost high power factor rectifier designed is rational and reliable, its power factor can reach 0.994.
