1. A vehicle on-board power conversion device installed in a vehicle, the vehicle including a power supply, one or more interior power supply ports arranged inside a passenger compartment of the vehicle, and one or more exterior power supply ports arranged outside the passenger compartment of the vehicle, the vehicle on-board power conversion device comprising:
an inverter configured to convert power output from the power supply; and
processing circuitry configured to control the inverter, wherein
the inverter includes
a first inverter circuit configured to convert power, output from the power supply, into single-phase two-wire alternating-current power and supply the single-phase two-wire alternating-current power to the one or more interior power supply ports, and
a second inverter circuit configured to convert power, output from the power supply, into single-phase two-wire alternating-current power and supply the single-phase two-wire alternating-current power to the one or more exterior power supply ports,
the processing circuitry is configured to
determine whether the vehicle is traveling, and
when determining that the vehicle is traveling, stop or limit supply of power to at least one exterior power supply port of the one or more exterior power supply ports,
the second inverter circuit includes a full-bridge inverter unit including switching elements, and
the processing circuitry is further configured such that:
when stopping the supply of power to the at least one exterior power supply port, the processing circuitry stops a switching control of the switching elements of the full-bridge inverter to set the power supplied to the at least one exterior power supply port to zero, and
when limiting the supply of power to the at least one exterior power supply port, the processing circuitry controls the switching elements of the full-bridge inverter to set the electric power supplied to the at least one exterior power supply port to a predetermined power greater than zero.
