Electric vehicles (EVs) are depending on reliable and efficient battery charging infrastructure. This work provides a 2 set of three phase ac-dc converter-based power-quality (PQ) compliant IEEE-519 battery charging system. The zigzag multi-winding transformers (ZZMWTs) will play a role in reducing total harmonic distortion (THD) without the use of any power factor correctors or filter circuits. The secondary side star and delta arrangement of the ZZMWTs will have a phase shift of $\pm \mathbf{15}^{\mathbf{0}}$. This paper focuses on designing, optimizing, and managing a DC-DC interleaved buck converter for EV battery charging in both constant current (CC) and constant voltage (CV) modes. The planned EV charger performance is assessed using the MATLAB/Simulink environment in terms of THD and PF. A laboratory prototype hardware arrangement of the suggested battery charger is used to validate the results while providing controlled feedback. To support the theoretical analysis, further experimental findings from the lab prototype are presented.
