摘要：

Stability analysis of the cascaded dc-dc power electronic system is analyzed in this paper. For demonstration boost converter supplying, the hybrid switched capacitor converter considered as an example. The boost converter is acting as the bus converter, 42 V bus, while the switched capacitor converter is serving as the point of load converter. The two converters are provided with voltage-mode and peak current-mode controllers, respectively. Converter state-space, two-port network models are developed and then stability of the cascaded system has been analyzed. Cascaded system interaction effects, (i) Source converter power handling capability with switching load and (ii) load converter interfacing capability with bus converter, are analyzed. Simulation and experimental results are provided for verification purpose. (C) 2009 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
