A power outputting device for outputting a motive power by driving a motor (22) rotationally using an electric power from a DC power source (32). This DC power source (32) is enabled, when cold, to exhibit its performance sufficiently by heating it quickly. In the power outputting device in which a capacitor (30) is mounted to connect an anode bus (26) and a cathode bus (28) of an inverter circuit (24) and in which the DC power source (32) is mounted to connect the cathode bus (28) of the inverter circuit (24) and a neutral point of the motor (22), an electronic control unit (40) switches transistors (T1 to T6) by setting the inter-terminal voltage of the capacitor (30) higher than at a normal time and the frequency of a carrier wave lower than at a normal time when the power temperature (Tb) of the DC power source (32) detected by a temperature sensor (50) is not higher than a threshold value (Tblow) at which a necessary electric power can be supplied to the motor (22). As a result, the ripple of the neutral-point current flowing through the DC power source (32) can be increased to promote the heat generation of the DC power source (32). |
