<P>PROBLEM TO BE SOLVED: To supply stably power required for a rotary electric machine and a load, in a drive power supply device for vehicle which performs power delivery through a rotary electric machine and an inverter mounted on the vehicle and which includes a plurality of power supply devices mutually connected in parallel. <P>SOLUTION: The drive power supply device for vehicle includes a plurality of power supply devices 3, 5 which perform power delivery through a rotary electric machine 1 and an inverter 2 mounted on a vehicle and which are connected in parallel mutually. The drive power supply device for vehicle includes: a plurality of controllable DC converting devices 4, 6 which are connected respectively between the inverter and the each power supply device and which convert power of corresponding power supply device, and which are connected in parallel mutually; and a control device 7 which controls timing and a flow rate at the time of start of flowing of each controllable DC converting device so that each controllable DC converting device may supply respectively the prescribed drive power to the rotary electric machine through the inverter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
