Abstract
In this paper, a simplified Power Factor Correction (PFC) converter based on Single-Ended Primary Inductor Converter (SEPIC) topology is proposed. In the proposed converter, a bridge diode at the input stage is deleted to reduce the conduction loss and improve the efficiency. Since the proposed converter operates under discontinuous conduction mode, the input current naturally follows the input voltage waveforms and provides high power factor without complex control. The presented theoretical analysis is verified by a prototype of 100 kHz and 150W. Also, the measured efficiency of the proposed converter has reached a value of 90.8% at the maximum output power.
