Design of a High Step-up DC-DC Power Converter with Voltage Multiplier Cells and Reduced Losses on Semiconductors for Photovoltaic Systems

A high step-up dc-dc converter based on an isolated dc-dc converter with voltage multiplier cells for photovoltaic systems is essentially introduced in this paper. The proposed converter can provide a high step-up voltage gain. The switch voltage stress and losses on semiconductors are significantly reduced through this work Furthermore, the proposed converter can reliably offer and provide continuous input current which can be basically used for integrating photovoltaic systems to convert 30 V to 480 V dc bus. The ripple on the input current is minimized due to the isolated converter, and the proposed converter is fed by a single input voltage. The operation modes and the characteristics of the aforementioned converter are thoroughly analyzed. The components selection, simulation results and experiment results are mainly verified by using MATALB Simulink. Consequently, a 360W hardware prototype is implemented to validate the design and the theory.
