This work presents a novel isolated dc-dc converter for an 800 to 48 V automotive application. The converter topology is derived from both a dual active bridge converter and a flying capacitor multilevel converter and leverages strengths from both converters. The proposed topology is validated in hardware, and demonstrates high efficiencies over 96% at this high conversion ratio making it a compelling alternative to a conventional dual active bridge converter.
