Classification: CPC H | IPC H

Claim 4:
5. The drive system according to claim 2, further comprising:
a high potential connection line that connects a high potential side of the first inverter and a high potential side of the second inverter;
a low potential connection line that connects a low potential side of the first inverter and a low potential side of the second inverter;
a third switch that is provided on at least one of the high potential connection line and the low potential connection line; and
a mode control unit that selectively performs, as a control mode, one of a first mode and a second mode,
the first mode maintaining, in the off state, the third switch, so that one of the receiving of the output power from the rotating electrical machine and the supply of the input power to the rotating electrical machine is performed by the switch drive task and the neutral-point drive task of the drive control unit,
the second mode maintaining, in the on state, the third switch, so that one of the receiving of the output power from the rotating electrical machine and the supply of the input power to the rotating electrical machine is performed via the high and low potential connection lines;

the selection unit is configured to perform selection between the first setting and the second setting when the mode control unit selectively performs the first mode; and
the drive control unit is configured to maintain, in the on state, at least one of the upper arm switch and the lower arm switch of the neutral-point drive inverter selected by the selection unit, the at least one of the upper arm switch and the lower arm switch being connected to the at least one of the high potential connection line and the low potential connection line.
