Nowadays, the integration of fast Electric Vehicle (EV) charging station with microgrid becomes very challenges due to non-linear behavior of load unit. These charging unit produce harmonic distortions which reduce the power quality. To ensuring the stable voltage and current profile as per IEEE standard while connecting Grid-to-Vehicle (G2V) has becomes challenging issue. In this paper, an efficient off board 3P3L4W (Three-Phase Three-Level Four-Wire) T-Type Vienna Rectifier (TTVR) for fast EV charging stations with suppressed Total Harmonic Distortion (THD) level and power quality enhancement is presented. TTVR interfaced with Improved Instantaneous real and reactive power (IIPQ) control strategy to maintain low switching losses, enhanced steady state and dynamic load response. Hence, this proposed Fuzzy Logic Controller based IIPQ control strategy has been employed to maintain constant DC-Link voltage and capacitor voltage VC1, VC2. This method is validated by using MATLAB and experimental validation also carried with 15KW laboratory prototype using digital signal peripheral Interface controller (dsPIC30F4011), Rapid Hyper-fast Recovery Glass (RHRG30120) power diodes and Silicon Carbide Metal-Oxide-Semiconductor Field-Effect Transistors (SiC MOSFETs IRFP260) switches to maintain high switching stress and low ON-State losses. The average THD value obtained is close to 2.5% which implies power quality enhancement, battery charging efficiency and highlighting the feasibility and adaptability of the proposed system for energy conversion and advanced EV charging station infrastructure development. © 2025 The Authors
