摘要: A new simple flyback AC/DC converter with harmonic current correction and fast output voltage regulation is presented. In the proposed AC/DC converter, an extra winding is wounded in transformer and yields two major merits: The bulk inductor used in the conventional boost-based PFC cell is omitted in the proposed converter and consequently almost 1/2 volume and weight in magnetic material can be saved. The voltage across bulk capacitor can be hold under 450v by tuning transformer windings ratio. even though the converter operates in wide range of input voltage (90vsimilar to265v/ac). This new converter complies with IEC 61000-3-2 under the load range of 200w and it has fast output voltage regulation.
