<P>PROBLEM TO BE SOLVED: To provide a combined mechano-electric electric driving apparatus that can return a common mode current from a rotary electric machine side to a virtual neutral point of a power conversion device in the electric driving apparatus. <P>SOLUTION: A combined mechano-electric electric driving apparatus includes: a rotary electric machine 900; a power conversion device 200; a conductor bar 950b and a conductor ring 950c; and connection wiring 700. The rotary electric machine 900 includes a rotor, a stator having a stator core 941 with an armature coil 945 mounted therearound, and a housing 912 for arranging AC terminals 902U-902W of the armature coil 945 and holding the stator. The power conversion device 200 has an inverter circuit 140 and AC bus bars 802U-802W for connecting the inverter circuit 140 and the AC terminals 902U-902W, and is fixed to an outer periphery of the housing 912. The conductor bar 950b and the conductor ring 950c are disposed in contact with the stator core 941 and collect a common mode current caused by a floating capacity of the stator. The connection wiring 700 connects a virtual neutral point 510G on a DC input side of the inverter circuit 140 and the conductor bar 950b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
