Reduction of Harmonics on Source Side Using Filters for EV Charging Applications

Due to decrease in fossil fuel, the future of automobile industry is completely depending on Electric vehicle. The comprehensive modelling and hardware installation of a harmonics compensation system based on a voltage source inverter that functions as an active filter are described in this paper. Shunt active power filters are the compensator that is mounted in parallel with the AC line (APF). In today’s battery charging stations, high voltage non-linear loads (rectifiers) are commonly used. This leads to injection of harmonics into power system. The controller system removes harmonics effectively, supply voltage is skewed.To produce firing angles for voltage source inverters, the Selective Harmonics Elimination PWM (SHEPWM) technique is used, which lowers the individual unit frequency deviation. In hardware, a distribution network that provides mixed linear and non-linear loads and utilizes VSI with a battery charging DC-DC converter is introduced. To calculate the proposed control output, voltage and current are determined. The total harmonic distortion (THD) can be calculated with the help of harmonic disruption charts. By designing a suitable filter the harmonics produced is also reduced. The performance of the electric car charger has increased as a result of this study.
