Solar Power Geared BLDC Motor for EV Incorporating Modified SEPIC Converter

Dr.B Mahesh Kumar, R Babu Ashok

This paper presents set of harnessing solar energy for electrical vehicle where BLDC machine is a sole heart of Electric Vehicle (EV). The solar Photo Voltaic (PV) array is modeled for study purpose. Requirement of huge voltage gain is fulfilled by a non-galvanic modified Single Ended Primary Inductor Converter (SEPIC). The conventional 3 phase H-bridge inverter (Voltage source Inverter (VSI) - SPWM drive based) is used in BLDC motor. Basic modeling of BLDC machine with few assumptions is used for entire experimentation to validate the analytical study. MATLAB based simulation is carried for a 2 HP BLDC machine system. The performances like Speed, Torque, Current, Voltage and Back emf of the system are analyzed , validated and resulting waveforms are confirming to battery equivalent system performances is given.
