6.6 kW High-Frequency DC-DC Converter

High efficiency and high power density are two key demands for switching mode power supplies. The technology development and applications of wide bandgap (WBG) power devices, such as Silicon Carbide (SiC) devices, have enabled themselves to the promising substitutions for traditional Silicon (Si) devices in a variety of applications. This whitepaper includes a description of the circuit operation and design of the Demo Board and the measured efficiency, key waveforms, regulation of the output voltage, and thermal measurement of the converter with a maximum output power of 6.6 kW.
