Abstract :
This paper presents the performance comparison and transfer efficiency modeling and analysis of a 4-quadrant switched capacitor Luo (4-Q SC Luo) converter and 2-Q SCC, applicable for hybrid electric and plug-in hybrid electric vehicles (PHEV) Energy storage system (ESS) applications. Features of voltage step-down, voltage step-up, and bi-directional power flow are integrated into a single circuit. The SCC 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 modes of operation (buck and boost modes).
