Unity power factor converter for high quality power supply with magnetically coupled compensation
 The present invention provides a high quality power supply, and more particularly to an improved single-ended converter having the high power factor close to unity. In accordance with the present invention, the power supply comprises a power source, a low-pass filter, a rectifier including an inductor, a transformer primary coil, a transformer secondary coil, a ripple energy storing capacitor, a switching controller and an inductance element wound round a core where said transformer primary and secondary coils are wound. The inductance element being coupled to said rectifying means so that compensates a voltage applied to said inductor in said rectifying means with a voltage applied to said transformer primary coil.
