Abstract

A single-stage bridgeless power-factor-correction (PFC) rectifier based on flyback topology is presented in this paper. The proposed rectifier substantially improves efficiency and power factor without the use of additional isolation stage. The operation and performance of the proposed circuit was verified with a 48-V 1-A prototype. The experimental results show that the circuit can attain efficiencies over 90 % and power factors over 0.92 for input range from 110-V to 230-V. The proposed design is suitable for wide-range input low-power offline applications.
