An Improved High Step-up Non Isolated DC-DC Converter: Steady-State Analysis, Design and Simulation

In this paper, an improved topology for a non-isolated high step-up DC-DC converter is proposed. The suggested converter has a straightforward structure, high voltage gains in comparison to the most non-isolated high gain structures shown in the literature, the low voltage stress on capacitors, low voltage stress on one of the switches and diodes, continuous input current, common ground, and low ripple in the output voltage and current. The continuous conduction mode (CCM) of the proposed converters, voltage stress on semiconductor devices, and component design are all fully considered in the mathematical analysis. The comparison results are addressed after the suggested converter has been compared to various converters offered in other references. The simulation findings of the proposed converter using PSCAD-EMTDC software are demonstrated to support the theoretical arguments.
