Title: Efficiency Investigation of BUCK DC-DC Converter with ZVS Using SPICE
Keywords: Power electronics, Switch mode power supply, Buck DC-DC conv
Abstract: In this paper the efficiency of BUCK DC-DC converter with Zero Voltage Switching (ZVS) is an object of investigation. A simulation scheme of Gate Driver with Adaptive Dead Time (ADT) is proposed, which provides the independence of ZVS from the current value at which the transistors are switched. The influence on the switching losses of an externally connected drain-source capacitor is simulated using PSpice. Macros in the graphical analyzer Probe are proposed for calculating the average value of the currents, the losses in transistors and the efficiency. The simulation results are presented graphically as a function of the junction temperature.
