Abstract

—This paper presents a full wave quasi-resonant zerocurrent switching buck converter design, simulation and application. The converter control uses with zero-current switching (ZCS) technique to decrease the switching losses. Comparing to conventional buck converter, resonant buck converter includes a resonant tank equipped with resonant inductor and capacitor. The converter is analyzed in mathematical for each subintervals. Depending on the desired input and output electrical quantities, converter is designed with subinterval equations. The converter is simulated in PSIM with design parameters. The simulation results are verified with experimental setup. The converter is controlled by UC3867N integrated resonant mode power supply controller
