Paper Zero current switching (ZCS) is one of the two resonant topologies in which the switching takes place while the current through the switch is zero. The focus of this work is on modeling a Buck Zero current switching (ZCS) Quasiresonant DC-to-DC converter using a domain independent modeling approach which is bond graph modeling approach. Development of the large signal model, steady state model and small signal AC bond graph models of the converter will be presented. Further the models are simulated in MATLAB/SIMULINK and the obtained results are verified with the results obtained by direct simulation of the converter in PSIM.
