Power outputting device and vehicle mounting it, control method, storing medium and program for the power outputting device, drive device and vehicle mounting it, and, control method, storing medium and program for the drive device
A power plant outputs motive power by driving a motor ( 22 ) using electric power from a direct-current power source ( 32 ). When the direct-current power source ( 32 ) has a low temperature, the direct-current power source is rapidly heated, whereby the performance can fully be demonstrated. In the...

| description | A power plant outputs motive power by driving a motor (
22
) using electric power from a direct-current power source (
32
). When the direct-current power source (
32
) has a low temperature, the direct-current power source is rapidly heated, whereby the performance can fully be demonstrated. In the power plant in which a capacitor (
30
) is installed so as to connect a positive electrode bus (
26
) and a negative electrode bus (
28
) of an inverter circuit (
24
) and the direct-current power source (
32
) is also installed so as to connect the negative electrode bus (
28
) of the inverter circuit (
24
) and a neutral point of the motor (
22
), when a power source temperature (Tb) of the direct-current power source (
32
) detected by a temperature sensor (
50
) is less than or equal to a threshold temperature (Tblow) at which supply of required electric power to the motor (
22
) is possible, an electronic control unit (
40
) sets a voltage between terminals of the capacitor (
30
) higher than normal and also sets a frequency of a carrier wave lower than normal, and performs switching control of transistors (T
1
to T
6
) Thus, a ripple of a neutral point current which flows into the direct-current power source (
32
) can be increased, whereby it is possible to promote calorification of the direct current power source (
32
). |
