Abstract :
A family of single-switch fixed frequency zero-current-switching (ZCS) power converters having lossless switching and low output ripple using a coupled inductor are proposed. The operating principle is illustrated by the different operating modes and the state-space analysis of a modified ZCS fixed frequency buck power converter. Design curves are obtained and a design example is presented. SPICE simulation results obtained for varying load conditions for the power converter designed are presented to verify the theory
