This paper focuses on enhancing the power factor of Electric Vehicle (EV) chargers through the implementation of a Bridgeless Isolated Zeta-Luo Converter. Poor power factor is a common feature of conventional charging systems, which increases energy losses and decreases efficiency. It is critical to address the serious environmental problems that transportation-related hydrocarbon emissions represent in the modern world. Electric car adoption is picking up steam as a means of promoting environmentally friendly transportation. The DC-DC converter is a vital part of these cars since it helps distribute power to auxiliary systems effectively. It guarantees the smooth operation of different vehicle sections by ensuring the efficient transmission of energy between systems operating at different voltage levels. The proposed converter aims to address this issue by employing a bridgeless topology and Zeta-Luo configuration, ensuring improved power factor correction and efficient energy transfer. The isolation feature enhances safety while maintaining a compact design. Through detailed analysis, simulation, this paper aims to demonstrate the effectiveness of the proposed solution in optimizing power factor and overall performance of EV chargers, contributing to the advancement of sustainable and efficient electric transportation infrastructure.
