This project presents a zero-current switching (ZCS) DC-DC buck converter design, simulation and application. The converter control uses with 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. Complete design-oriented mathematical calculations were done for ZCS converter. The converter is simulated in OrCAD Capture CIS software with design parameters. The simulation result show that the switching losses using ZCS technique is less compared to conventional buck converter.
