This paper presents a new design for bridge-type AC/DC converters with natural input current shaper. They have a fast output voltage regulation in full range input (85V~265 V/AC). An additional winding in main transformer can naturally modify a line current. Further, the additional winding reduces an input inductance, so the weight and size of magnetic material are significantly reduced. The total...

This paper presents a new simple forward AC/DC converter with harmonic current correction and fast output voltage regulation. In the proposed AC/DC converter, an extra winding wounded in transformer provides two major merits: The function of bulk inductor has been replaced by tills extra back-feeding transformer winding in the proposed converter and significant volume and weight in magnetic material...
