摘要

A novel controller for a switched capacitor (SC) bidirectional DC/DC converter is proposed for plug-in hybrid electric vehicle energy storage systems, with simultaneous step-up and step-down output voltages. The novel control strategy enables simpler dynamics compared to a standard buck converter with input filter, good regulation capability, lower source current ripple, ease of control, and continuous input current waveform in both modes of operation (buck and boost modes). A detailed efficiency modeling and analysis is also presented to support the claims.
