A new forward-based single-stage power-factor-corrected converter is proposed. A portion of input power is directly transferred to the output through the forward converter to improve the efficiency of power conversion. The flyback auxiliary circuit is added to the forward converter to reduce low line-frequency output voltage ripple. In an effort to lower the size and cost of the converter, a single transformer is used for all the power conversion with Time Multiplexing Control (TMC). The simulation results confirm the effectiveness of the proposed scheme with high power factor and tight output regulation.
