Electric vehicles are treated as the future of automotive technologies as they help to solve the energy shortage and act as a clean source of energy. The electric vehicle charging station technology has progressed continuously, and it will dominate the load scenario in the near future. The non-linear nature of the loads at charging stations has contributed to the harmonic emissions and impacted the power quality of the distribution system. In this paper, the simulation for harmonics mitigation at charging stations is Developed using MATLAB/Simulink. A non-linear notch filter, viz. enhanced phase-locked loop (EPLL), is used for implementation of active power filter at the charging station. The EPLL-based active filter is used for reference current generation and acts as an excellent frequency domain technique for estimation of harmonics for a non-linear load. The control algorithm is implemented using low-cost target platforms like Arduino and C2000-based Launchpads from Texas Instruments. Moreover, with a single algorithm, it is possible to detect the harmonics as well as synchronize the current injected by active power filter in the power system. Additionally, fuzzy logic controller and sliding mode controllers are used to maintain constant voltage across the DC link of inverter in active power filter. The simulation results show that there is a significant improvement in the current profile, and the total harmonic distortion of the source current meets the IEEE 519 standard.
