Abstract

The paper presents a new sampled data model for a self-oscillating series parallel resonant converter including the effect of the transformer leakage inductance, and the output capacitor filter parasitic resistance. The generalized set of the piecewise linear state space model is given, and then a systematic procedure is shown to develop the dynamic models in general steps. The steps are translated into a MATLAB program that is 30 times faster and 150 times less capacity than that of the PSIM software. The algorithm is applied to model the converter in both of the undamped (continuous) and clamped (discontinuous) conduction modes. Analytical, simulation and preliminary experimental results are given to prove the validity of the developed models
