Abstract

A 5 kW multilevel modular capacitor clamped dc-dc converter (MMCCC) for future hybrid electric vehicle and fuel cell automotive applications will be presented in this paper. The modular structure of the MMCCC topology was utilized to build this 5 kW converter with high reliability and fault bypassing capability. Moreover, the circuit has flexible conversion ratio that leads to establish bi-directional power management for automotive applications. In addition, the MMCCC exhibits better component utilization compared to the well known flying capacitor dc-dc converter. Thus, the MMCCC circuit can be made more compact and reliable compared to many other capacitor clamped dc-dc converters for high power applications.
