Modeling and performance analysis of a novel switched capacitor boost derived hybrid converter for solar photovoltaic applications

Abstract In this paper a novel switched capacitor boost derived hybrid converter (SCBDHC) topology is proposed to generate hybrid output of AC and DC simultaneously in higher range from a single DC input source for a solar PV AC load and DC load applications. This hybrid topology employs less number of switches for the conversion of DC to DC and DC to AC, compared with the traditional conversion techniques, as seen in the literature, reduction in switches causes reduction in power loss and overall cost of the system and may result in increased reliability and efficiency in the medium and high power applications. State space modeling of the SCBDHC has been developed and the steady-state currents and voltages have been computed and verified with MATLAB/Simulink. A closed loop scheme developed and helped regulation of the source and load fluctuations and its performance was verified with an experimental setup.
