FPGA-Based Phase-Shift ZVS Full-Bridge DC-DC Converter Using One-Comparator Counter-Based PWM Control Strategy

This paper applies the one-comparator counter- based PWM (pulse-width-modulated) control strategy to controlling the FPGA (field programmable gate arrays)-based phase-shift ZVS full-bridge DC-DC converter based on two output inductors with direct coupling. To verify the performance of the proposed control schemes, some transient load variations are imposed on the constructed converter.
