Voltage Multiplier Cells Non-isolated Dual Input DC-DC Converter with Wide Voltage Gain for EV Charging Applications

Abstract

This paper will give Voltage Multiplier Cells based Non-isolated multi-port(VMC-NIMP) DC-DC converter utilizing a switched capacitor design which integrated with Hybrid energy sources based Photo voltaic (PV) -Fuel cell (FC) to EV charging applications. A non-isolated transformer-less Multi-Port DC-DC Converter is designed with the integration of hybrid energy sources. A voltage multiplier circuit will boost and improve the converter's gain. This design is having lesser ripples when compared to available converters. This has fewer components and a higher gain than the existing converters. This designed converter features a wider voltage enhancement, less voltage stress on the power switches, and a shared ground connection between the input and output terminals. This will gives operational modes, steady-state and comparison analysis to show the converter's importance in EV-Charging applications. © 2025 IEEE.
