Abstract
In this paper a parallel soft- switching power factor correction circuit is proposed. This converter is based on an active clamp flyback circuit. Power factor correction is achieved with minimum double process of power, while providing ZVS condition for the main switch and the auxiliary switch. The proposed converter processes 68% of input power once and the 32% of power is processed twice, so the efficiency is improved in comparison with other PFC converters. Simulation results of the proposed converter are presented and compared with IEC standard limitations. The results confirm the theoretical analysis.
