<P>PROBLEM TO BE SOLVED: To prevent a current sensor from receiving magnetic interference caused by current flowing in a conductor between a motor and an inverter while using a core-less current sensor that detects current flowing in a booster circuit. <P>SOLUTION: A bus bar BCL connecting a battery with a step-up converter is disposed between a pair of bus bars which respectively connect first and second inverters with motor generators MG1 and MG2, that is, the bus bar BCL is disposed between a rightmost bus bar BW1 for MG1 and a leftmost bus bar BU2 for MG2. Current sensors SW1 and SU2 with magnetism collection cores CW1 and CU2 are respectively arranged in the bus bars BW1 and BU2 to measure current flowing in the bus bars BW1 and BU2 respectively. A core-less current sensor SCL is arranged between the magnetism collection cores CW1 and CU2 in the bus bar BCL to detect current flowing in the bus bar BCL. <P>COPYRIGHT: (C)2013,JPO&INPIT |
