Feasibility of High Frequency Zero-Voltage Switching Boost Converters Achieving High Power Density Using Wide-Bandgap Devices

Abstract

This paper describes a study of feasibility of achieving high power density (exceeding 10 kW/L) in high frequency (several hundred kHz) interleaved ZVS DC/DC boost converters by applying wide bandgap semiconductor devices. Simulation results, the PCB design and experimental results are presented. Simulation results confirm a possibility of such a converter working at high power density. However, the designed converter was able to achieve 5.5 kW/L power density. The limiting factors are identified and possible solutions to be implemented in future work are given.
