Abstract: This paper presents the analysis and novel controller design for a two-quadrant hybrid switched capacitor (SC) converter and interleaved two-quadrant SC bidirectional DC/DC converter for a hybrid electric vehicle dual energy storage system. The designed novel control strategy enables simpler dynamics compared to a standard buck converter with input filter, good regulation capability, low EMI, lower source current ripple, ease of control, and continuous input current waveform in both buck as well as boost modes of operation.
