Abstrakt

A high step-up switched-capacitor based converter is proposed in this paper. The proposed converter features high conversion ratio, low voltage stress and continuous input current, which makes it very suitable for renewable energy applications like photovoltaic systems. More importantly, the proposed switched-capacitor cells in series with converter can be generalized in two ways, resulting in dc-dc converters of ultra-high dc conversion ratios. Theoretical analysis, simulation and experimental tests have demonstrated the superior performance of the proposed converter in terms of high dc voltage gain, low voltage stress on the switches, continuous input current, and relatively high efficiency.
