Study of 3-Phase Embedded Charger for Vehicle-to-Home (V2H) Under Unbalanced Load Conditions

This paper provides a comprehensive exam- ination of various Vehicle-to-Everything (V2X) scenarios, emphasising on those that pose significant challenges. A focus is given to the Vehicle-to-Load/Home (V2L/H) scenario, where a three-phase embedded charger is tasked with powering a single-phase load. In this context, it is crucial to properly manage the load’s neutral to ensure the voltages delivered by the charger remain balanced. The paper delves into two potential methods for neutral connection, elucidating the implications each method has on the power electronics involved.
