Bidirectional PV-Powered Battery Charger for Electric Vehicle

In the automotive industry, electrical vehicles (EVs) are a relatively new technologicaldevelopment. The majority of cars on the road today run on fossil fuels like gasoline and diesel, whichpollutes the environment by raising CO2 and other harmful gas emissions. Additionally, there is a growingscarcity of fossil fuels. Electric vehicles are introduced as a solution to the aforementioned problem. Thebidirectional DC-DC buck-boost converter modeling and analysis for battery energy storage systems andphotovoltaic panels are presented in this work. PV panels operate based on the available irradiance. ThePV array will use a bidirectional DC-DC converter to charge the battery and supply power to the loadwhen the irradiance increases enough to generate that voltage. The battery will supply the load using thesame bidirectional DC-DC converter when the PV array's irradiance is insufficient to create a suitablevoltage, at which point the battery will drain through the load. Since traditional buck or boost convertersare incapable of producing bidirectional power flow, buck and boost converters are connected inopposition to one another to create a bidirectional DC-DC power flow converter. This study presents thevoltage across the load and the battery's charging and discharging behavior in relation to the availability ofirradiance. Various proportional integral controllers are modeled and designed to generate the requiredduty cycle for MOSFET/IGBT switches in order to obtain satisfactory results.
