Hybrid Converter for Roof-Top Mounted Solar PV and Battery Integrated Light Electric Vehicle

This work propose a Three-phase Boost Derived Hybrid Converter (TPBDHC) for roof-top solar PV mounted light electric vehicle with battery support which supplies both three phase AC as well as DC loads, simultaneously using single DC source. Here solar power along with battery system is used to drive the three phase motor and other DC loads using proposed hybrid converter topology. When vehicle is in standing mode, the solar PV power is used to charge Li-ion battery and when in running mode, the available solar power along with battery is used to power the EV motor and other auxiliary loads using the proposed hybrid converter. Here we have used constant frequency shoot through sinusoidal pulse width modulation (CFST-SPWM) control scheme to generate gate pulses for the switches. The shoot-through state is provided to perform boost operation of the converter. In this work performance of proposed TPBDHC is evaluated for solar and battery powered electric vehicle. The simulation studies has been performed to verify the operation of the proposed hybrid converter using MATLAB/Simulink.
