Abstract
A power output apparatus includes first and second motor generators, first and second inverters and a relay circuit. The first and second motor generators include first and second 3-phase coils, respectively. The first inverter alters periodically the potential at a first neutral point of the 3-phase coil. The second inverter alters periodically the potential of the second neutral point of the second 3-phase coil at phase corresponding to a phase-inverted version of the potential change of the first neutral point. The relay circuit responds to a control signal from the control device to electrically connect first and second AC lines to a connector, and provides an alternating voltage generated across the first and second neutral points to the connector.
