This paper proposes a novel approach to enhance the robustness of EV onboard charger by employing an H∞ controller design. The H∞ control methodology is utilized to mitigate the adverse effects of weak grid conditions such as voltage fluctuations and harmonics, thereby ensuring reliable and stable charging operations. This paper presents a combo 3ph/1ph rectifier for on-board charger of electric vehicle which can work with 1ph and 3ph supply. The proposed controller design is implemented and evaluated through comprehensive simulations and experimental validations, demonstrating its effectiveness in enhancing grid resilience while maintaining high efficiency charging and minimizing system disturbances. The results highlight the capability of the H∞ controller to provide robust performance under varying grid conditions, making it promising solution for the next generation of EV charging infrastructure aimed at bolstering grid resilience and stability.
