| Abstract: | The characteristics of a novel single-switch near-zero-output-current-ripple AC-DC converter with high power factor are studied. This converter eliminates the need for reset windings and output inductors to obtain near-zero output current ripple. The passive clamping circuit can effectively recycle transformer leakage energy and reduce the switch voltage stress. In addition, high power factor is achieved in this converter. The topology, principle of operation, simulation and experimental results are reported. |
