Abstract

A non-isolated high boost DC-DC converter topology based on a switched-capacitor (SC) structure is introduced in this paper. By controlling the duty cycle in each period, the voltage gain of the converter is adjusted. The main features of the proposed SC converter are the continuous input current, achieving high voltage gain with low voltage and current stress on the power components, no use of a high-frequency transformer, and easy to increase the voltage by adding the SC cell. To correct the operating analysis, a 200-W output power prototype was built with the input voltage in the range of [25 V, 50 V] and the output voltage of 200 V. The proposed inverter reaches a maximum efficiency of 93% at the input voltage of 25 V and the output power of 150 W. The simulation and experimental verifications match the analysis.
