Modeling of Series Resonant DC-DC Power Converters

In the work are realized and presented models of the most commonly used series resonant DC-DC converters: a serial and a parallel loaded capacitor. Models are synthesized using differential equations and switching functions. In this way, it is convenient to formalize the power circuits in question and complex mathematical software does not have to be used to solve the system of differential equations. The obtained models allow to synthesize robust control of the converters and perform optimization on certain criteria. The proposed modeling approach is very suitable for use in power electronics training because it allows the description of various electronic energy converters where there is a switch between two or more states.
