150 Watts and 140 kHz multi-output LCC-type parallel resonant converter

By using the state-plane approach, the steady state analysis and design of a high-frequency LCC-type parallel resonant converter (PRC-LCC) operating in the continuous conduction mode is presented. In this topology a capacitor is added in series to the inductor of a conventional PRC. Based on this analysis, a set of steady-state characteristic curves for component value selections and device ratings is also presented. A simple design procedure is given and a design example for a 150 W, 140 kHz multioutput PRC-LCC power supply is given. Results from a prototype unit built to verify the theoretical results are shown to be in reasonable agreement with predicted results.<
