Abstract - A PV based modified SEPIC converter for microgrid applications is developed to increase the reliability and to reduce the operating cost of Electric vehicle. In the modern area, people are facing problems like pollution and outage of fossil fuels which may become reason for the human destruction. PV modified based SEPIC Converter fed Electric vehicle can run without use of any Charging stations. Here the number of PV Arrays used can also be reduced by using SEPIC Converter, and the voltage can be boosted. SEPIC converter is placed in between PV array and Battery of Electric vehicle. Use of (VSI) Voltage Source Inverter helps and it to vary the speed of Electric vehicle smoothly in steps. The proposed converter is able to attain a higher voltage gain in comparison with similar previous transformer-less DC–DC converters. Also, the proposed converter presents low-voltage stress across the switch and output diode. The proposed converter is controlled through a single switch and there is no limitation for a range of duty ratios. The voltage gain analysis of the proposed converter is done in continuous conduction mode and discontinuous conduction mode, also comparative analysis is done with the existing topologies with similar features. BLDC motors are known for their high performance, and long lifespan. minimize the cost of PV system-wide power generation while also improving the system's performance. All the simulation work is done in MATLAB.
