Cost efficient and timely power converter circuit design requires minimization of the number of breadboard iterations. This can be accomplished through the use of computer-aided analysis tools that are capable of predicting the circuit performance accurately. New physics based models for the circuit components, in particular for power semiconductor devices, are being utilized. This paper presents a comprehensive study of the use of accurate power MOSFET models in the design of resonant power converters. The influence of device parameters on the circuit performance is investigated in detail. A lMHz resonant converter circuit is simulated and circuit waveforms agree with breadboard measurements to a high level of accuracy. Thus, design optimization can be performed through simulations without the need of breadboard iterations.
