| Abstract |
In this paper, We present a low cost auxiliary circuit of S⁴-PFC converter with the feedback winding, which can improve the input current waveform with the maintenance of limited DC Bus Voltage and high efficiency. The converter with feedback winding was analyzed to demonstrate the proposed converter. In order to verify the performance of the proposed converter, we designed the converter which operates at the output of 5[V], 65[W] and switching frequency of 100[kHz] within the universal line voltage. Implemented converter has decreased line current peak value by 50[%] compared with the conventional converters and the power utilization was increased in the line period |
