Abstract :
The characteristics of a novel single-switch high-power-factor regulator with low output current ripple are studied. By employing a modified-boost converter cell as the input stage and a double-ended forward converter cell as the output stage, a high power factor and near-zero output current ripple are achieved. This regulator also eliminates the need for an extra clamping switch to recycle the transformer leakage energy and to reduce the switch voltage stress. The analysis, design, simulation, and experimental results are reported to verify the operation and performance of the proposed regulator.
