Abstract:
A vehicle driving device includes a permanent magnet motor, an inverter that drives the permanent magnet motor, a DC-to-DC converter that is a buck-boost converter and connected to the inverter, and a driving battery that is connected to the DC-to-DC converter. The DC-to-DC converter outputs, to the inverter, (i) a voltage inputted to the DC-to-DC converter of a positive electrode of the driving battery as-is and (ii) a voltage inputted to the DC-to-DC converter of a negative electrode of the driving battery after increasing the voltage in a negative direction.
