The Performance of Buck DC-DC Converter for Gate Driver with Adaptive Dead Time

Abstract: In the current work we studied the performance of the BUCK DC-DC converter with Zero Voltage Switching (ZVS). To test the object, we have advocated a simulation scheme of Gate Driver with Adaptive Dead Time. It enables the independence of ZVS from the current value at which the transistors are switched. We have simulated the influence on the switching losses of an externally connected drain-source capacitor. It is important to measure the mean value of the currents, the losses in transistors and the efficiency for which Macros in the graphical analyser is required. Trial data is obtained for testing the functions.
