This paper presents a comparison of isolation converters based on Si, SiC, or GaN switching devices for level-2 integrated onboard chargers. The isolation converters all employ a dual active bridge for bidirectional power flow for the charger and a buck converter tapped off the same transformer for powering the 14V vehicle loads. Design trade-offs and operating constraints are discussed and performance metrics in terms of efficiency and power density and experimental results are included.
