Research And Design

A 100W adaptor with universal voltage range 90-265VAC input and 20V/5A output is designed in this paper .The prototype adopted a new level two-stage high power factor power adapter, the PFC(Power Factor Correction) is a Boost converter operating in discontinuous current mode boundary,and the DC/AC using flyback converters. The experimental results showed that the effectiveness of the proposed approach.
