Abstract

A charging system for a vehicle is provided. The charging system is for charging an energy storage system of the vehicle using grid power. The grid power may be an external three-phase AC. The charging system may use field weakening techniques to reduce a peak line-line voltage detected at input terminals of conversion circuitry when a need is determined.
