Abstract
During a single-phase three-wire output control process for causing a neutral point clamped inverter circuit to have a single-phase three-wire output, a power converter performs a potential control process for changing a potential of the O terminal to a positive or negative value to allow more power to be consumed from power stored in one of first and second capacitors with a higher voltage than from power stored in the other one of the first and second capacitors.
