Abstract: Upon power failure of a commercial power source, an automatic switching device switches to power supply from a hybrid vehicle. An ECU of the vehicle, when receiving a request for generation of a commercial AC voltage, sets an upper-limit power generation amount based on a remaining amount of fuel. The ECU transmits the upper-limit power generation amount via an antenna to an on-premises ECU, while controlling a power generation amount based on the upper-limit power generation amount. The on-premises, when receiving the upper-limit power generation amount, controls the load state such that commercial AC power is supplied firstly to a first load of priority level 1, according to proprieties registered in advance, and such that the amount of the power supplied to the electric loads does not exceed the upper-limit power generation amount.

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.

Abstract: A matrix converter (38) converts three-phase AC power input from a first motor-generator (MG1) directly to three-phase AC power for driving a second motor-generator (MG2) and outputs the resultant three-phase AC power, without rectifying the three-phase AC power generated by the first motor-generator (MG1) once to DC power as in an example using a conventional three-phase full-wave rectification inverter. In a power supply system for a vehicle (14), the three-phase AC power is transmitted and received between two motor-generators (MG1, MG2) more directly, by means of the matrix converter (38). Therefore, power loss can be reduced, as compared with a conventional example in which the three-phase AC power is once converted to DC power. Thus, a power supply system for a vehicle with improved energy efficiency and a vehicle including the same can be provided.
