Abstract: This paper presents a novel simple forward ac/dc converter with harmonic current correction and fast output voltage regulation. In the proposed ac/dc converter, a transformer incorporating reset winding provides two main advantages. First, the bulk inductor used in the conventional boost-based power-factor-correction cell is omitted in the proposed converter, allowing significant volume and weight of magnetic material to be saved. Second, the voltage across the bulk capacitor can be held under 450 V by adjusting the transformer winding ratio, despite the converter operating in a wide range of input voltages (90similar to265 V/ac). This new converter complies with IEC 61000-3-2 under a load range of 200 W and has fast output voltage regulation.
