Abstract

Pulse width modulated (PWM) converters are suffering from poor efficiency due to high switching losses. quasiresonant converters with the help of resonance phenomenon can come to the rescue of PWM converters. There are certain problems even with the quasiresonant converters. Problems with quasiresonant converters such as parasitic oscillations and high voltage stress can be resolved with the help of multiresonant converters. Appropriate modeling technique is needed to accurately represent the physical system. The multiresonant converters along with electrical systems are involved in magnetic and thermal systems. For this kind of systems, the appropriate modeling is bond graph. In this piece of work, buck ZVS multiresonant converter is taken to model using bond graphs. The large signal bond graph model is created. In MATLAB/SIMULINK for state variables the created bond graph model is simulated. The findings obtained are checked with PSIM simulated results and experimental results. The comparison of model and experimental results prove the model’s accuracy.
