Abstract:

With the rapid adoption of Electric vehicles, the demand for Electric vehicle charging stations has increased.However, these

stations pose unique challenges in terms of power quality and harmonic distortion due to the high-power charging equipment. Due

to electric vehicles are viewed as nonlinear loads and have a knack to utilise enormous quantities of power in a brief period, they

have the potential to create instability in the power system. In addition, a notable increase in the numberof EVsconnected to the

grid can make the power system more vulnerable to disruptions. This abstract presents a solution for harmonic mitigation in EV

Charging Stations through the implementation of a multilevel inverter system. This multilevel inverters can provide high-quality

output voltage with reducedharmonic content. It not only improves power quality but also contributes tothe sustainable growth of

the EV ecosystem by enhancing the reliability and performance of charging stations. A sophisticated fifth order cascaded inverter

approach is presented in this research. The Offset-Based Carrier Pulse Width Modulation (PWM) technique is a method used in

inverter control to optimize the generation of pulse-width modulated signals. The intentional introduction of offsets contributes to

the reduction of harmonic distortions in the output waveform. By adjusting the pulse timings, the technique can minimize unwanted

harmonics, resulting in a cleaner and more sinusoidal output. MATLAB Simulation is used to validate the suggested control.

Simulation results demonstrate that the suggested solution reduces the total amount of harmonic distortion (THD) of voltage and

current within acceptable bounds.
