The main objective of this work is to find the high efficiency DC to DC boost converter for solar power installation system. This paper mainly focuses the modeling of high gain with high efficiency DC to DC boost converter for photovoltaic system under wide input voltage range. The modeling and Matlab simulink simulation of an interleaved and a cascaded DC to DC boost converters are presented. An interleaved and a cascaded DC to DC boost converters are analyzed in open loop and closed loop condition. These converters provide the constant output voltage even the output voltage of the PV panel is continuously varying. The performance of these converters is compared. Based on the comparison result the cascaded boost converter is implemented using PIC microcontroller. This comparison reveals that the cascaded boost converter system has the advantages like reduced number of switching component, low ripple content and high efficiency.read more
