Abstract :
A novel power factor correction (PFC) circuit is proposed which is constructed by one stage using a single forward AC/DC converter. This PFC circuit has functions of high power factor and suppression of the output voltage ripple. The high power factor is accomplished by operation in the discontinuous conduction mode, and the suppression of the output voltage ripple by using the exciting energy of the transformer in the forward converter
