Photovoltaic Driven Versatile Single In Dual Out NonIsolated Converter for Electric Vehicle Charging System

Grid-connected electric vehicles (EVs) are often powered by electricity from fossil fuels, which contributes to carbon dioxide (CO2) emissions during production. To promote a more sustainable approach, EV charging powered by renewable energy offers an environmentally friendly alternative to EV charging and transportation systems, known as “green mobility.” This research proposes a photovoltaic (PV)-assisted EV charging system using a non-isolated, single-input, dual-output electronic DC-DC power converter. It aims to provide a highly efficient and cost-effective charging solution by integrating renewable energy production directly into the EV charging infrastructure. This paper presents a novel design for a high-voltage gain, non-isolated DC/DC converter. This converter meets high conversion ratio requirements by combining a dual boost converter with a switched inductor configuration. The proposed converter operates in constant current mode (CCM) with an appropriate duty cycle and zero current in all switches and diodes. The proposed SIDO converter is designed in MATLAB/Simulink and tested in a laboratory environment with a hardware setup. This design offers many advantages such as a wide duty cycle range, low switching stress and losses, high efficiency, and high output voltage gain, making it suitable for a variety of applications.
