Abstract
Stability analysis of the DC-DC power electronic system is analyzed in this paper using a G-parameter approach. For demonstration boost converter cascaded with 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 the point of load converter. The two converters are provided with voltage-mode and peak-current-mode controllers, respectively. Converter two-port G-parameter 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.
