The Analysis of Dead Time Variation on Switching Loss in High and Low Side Mosfets of ZVS Synchronous Buck Converter Circuit

This work is about the analysis of dead time variation on switching losses in a Zero Voltage Switching (ZVS) synchronous buck converter (SBC) circuit. In high frequency converter circuits, switching losses are commonly linked with high and low side switches of SBC circuit. They are activated externa...
