    Power electronic converters are one of the key facets of modern electric vehicle (EV) charging applications. In the last few years, many EV charging manufacturers have been convinced that robust power converters and fault tolerance are essential for successful EV adoption, and cost-effective and simple fault tolerance techniques are necessary to achieve widespread EV use. The rise in the input current harmonics leads to a poorer power factor on the grid side during an open switch fault condition. The proposed controller provides better performance despite the open-switch fault occurring in any phase. The proposed voltage-oriented controller with Vienna rectifier helps to reduce the input current THD to less than 5% and unity power factor at AC mains, which meets the IEEE-519 standards.
