Efficiency Enhancement of Solar PV Battery Fed Electric Vehicles through Transformerless Buck Boost Converter and Bidirectional DC DC Control

In recent years, there has been a rise in automotive research on renewable energy based battery charging systems for electric vehicles EV . This study fully examines a solar PV battery fed electric car using a transformerless buck boost converter. Among the several advantages of employing batteries to store energy in ground vehicles are zero emissions, load levelling, and great transient performance. To achieve these requirements, a bidirectional DC DC converter is required to connect the PV to the batterys dc link. A PV powered electric vehicle must be capable of charging and discharging in two separate modes. In this research, the Maximum Power Point Tracking MPPT approach is used to gather the most electricity from solar PV. Moreover, a DC DC converter with bidirectional output necessitates the use of a closed loop control circuit, which is suggested in this study. To boost efficiency, a novel solar MPPT system with an integrated transformerless Buck Boost power converter was created. The article explains the Buck boost power inverters analysis, modelling, and control. To enhance PV energy extraction, the transformerless Buck Boost power inverter incorporates a super boost converter and a buck converter through a variable mode controller. Lastly, research on the MPPT system with battery chargers and DC loads is carried out. Experiment findings reveal that output power rises clearly with increasing sun radiation. MATLAB simulations are performed to validate the systems effectiveness.
