The method includes receiving an input power signal from an AC power source at a multi-level motor control system that includes a DC bus and a multi-level inverter configured to supply a load, the DC bus having a DC midpoint, connecting a DC midpoint of a DC bus to a neutral point of the AC power source, while isolating a neutral point of a load supplied by the multi-level inverter from the DC midpoint, monitoring a voltage on the DC midpoint of the DC bus. In addition, the method may include controlling a voltage of the neutral point of the AC load based on imbalances in the load supplied by the multi-level inverter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Alternate grounding of inverter midpoint for three level switching control","description":"A method of and system for controlling a DC midpoint of a multi-level inverter.
