Abstract :
This paper describes the formulation and verification of a SPICE macromodel for a practical series resonant converter circuit with parasitics. The macromodel is obtained by using a new proposed model of the power devices compared to the generic macromodel we have previously published. A 600 W series resonant converter has been built. Measurements of losses in each power device of the converter have been made. Macromodel simulation results based on the new power device loss model have been compared with the experimental measurements, and the results are found to be in excellent agreement
