In recent times, the prominence of permanent magnet BLDC motor is highly proliferating in all domestic, commercial, and industrial appliances, including the electric vehicle (EV) drives. The present research explicates the interfacing of a solar panel and grid with the electric vehicle like electric train. To produce higher dc voltage with a negligible switching loss, a novel interleaved SEPIC converter is employed in this study since can operate at low duty cycle. The output of the converter is associated with the BLDC motor-fed electric train and grid through a three-phase and single-phase inverters, respectively. The switching action of the inverter is controlled by a PI controller. During the daytime, the obtained output of PV is supplied to the electric train and grid, through which the solar power is fully used without any wastage, but at the night time, the power is supplied from the grid to EV through a converter. Thus the dual source topology with a single converter configuration is achieved. This low loss drive system requires no battery arrangements, which makes it simple and cost effective. The operation of the proposed converter is simulated in MATLAB and the test results are validated with the experimental prototype setup.
