<P>PROBLEM TO BE SOLVED: To provide a power control unit to be mounted on a vehicle, for controlling motor generators on the basis of power of a battery, while achieving proper switching control in consideration of the temperature of the battery. <P>SOLUTION: A power control unit includes an inductive circuit having a reactor 14 and a bypass switch 16; a switching circuit 18 that switches current flowing from a battery 10 to the inductive circuit and outputs voltage on the basis of output voltage of the battery 10 and voltage across current input/output ends of the inductive circuit; and first and second inverters 22 and 26 for controlling first and second motor generators 24 and 28, respectively, on the basis of the output voltage of the switching circuit 18. The bypass switch 16 operates according to the temperature of the battery 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
