Abstract
An improved magnetically integrated power converter which are provided specifically for use with power supplies with high density requirements. The converters comprise an integrated magnetic device integrating the functions of two transformers and three inductors. The integrated magnetic device is implemented on a three-leg core with two secondary windings and one primary winding, each winding on one of the core legs. The primary winding connects to the input dc voltage source by either a forward type arrangement or a half-bridge type circuit arrangement. Each secondary winding connects to the output through a rectifier. The turns number for two secondary windings can be different in order to achieve wider input range or reduced voltage stress.
