Abstract

A 150W series-parallel resonant converter dedicated for audio-video equipment is proposed. The converter utilizes an integrated magnetic component that allows for easier inductor design and improvement in size and efficiency. A performance analysis focusing converter losses is conducted followed by creation of a simulation model, that includes various sources of losses is presented. The simulation model includes a simplified method for calculating core losses based on the common core parameters and the value of the flux flowing through that core. Lastly the converter simulation model is verified with measurement from a physical model. The establishment of this kind of model will useful in the future for predicting performance when different control schemes are applied.
