Comparison of High Voltage Switches in Automotive DC-DC Converter

A comparison between trench IGBT, trench MOSFET and superjunction MOSFET is provided in the context of an automotive full bridge DC to DC converter. The converter is analyzed in both hard switching and phase shifted ZVS operation in 3 different voltage ranges (medium, high and extended ranges). After calculating the device loss models, the results are provided as trade-off curves function of normalized cost.
