摘要： External power supply system includes an electrical storage device, motor, inverter that drives the motor by using electric power of the electrical storage device, and a control device controls the inverter. The inverter includes a first and second switching elements connected in series with each other between a positive and negative electrode power supply lines. A connection-node of the first and second switching elements is connected to one corresponding stator coil. The control device inputs signals to the inverter to drive the inverter such that voltage at the neutral point becomes a predetermined value. The control device compensates for signals in dead time period, the period in which off-state signals are supplied to the first and second switching elements, on the basis of current that is input from the connection-node to one corresponding stator coil or output from one corresponding stator coil to the connection-node while an engine is driven.
