Analysis of Solar Photovoltaic Integration and Plug-in Electric Vehicle Charging Systems with a Bidirectional Buck-Boost DC to DC Converter

Renewable energy-powered plug-in electric vehicle (PEV) charging stations have gained popularity in recent years, especially in commercial and business-oriented environments. Several studies have investigated the use of solar photovoltaic (SPV) technology in a wide-spectrum bidirectional buck-boost DC-to-DC converter. Used in the grid-to-vehicle power export (VPE) and -ingestion (VPI) modes of operation, this combination system is designed for electric-powered vehicle packages like PEVs. In all operating modes, the converter achieves a satisfactory voltage switch ratio (VSR) with the suggested system setup, and there are no theoretical output voltage hurdles. In terms of flexibility, redundancy, and usability, it provides proof that it is suitable for PEV uses. In order to verify the theoretical assessment, an experimental model with 400 W was built and tested. The data shows that this improved method is successful and useful, with a peak efficiency of 97.4 percent when operating in VPE mode and 97.1 percent while operating in VPI mode. The results demonstrate the viability and practicality of the bidirectional buck-boost DC to DC converter, which enhances VPE-VPI operations in PEV charging structures and works well with the recommended combination of SPV and PEV charging systems.
