Abstract:
A control apparatus for a multi-phase rotating electric machine includes at least one electric power converter, a command value calculator and an input voltage determiner. The at least one electric power converter converts DC power into multi-phase AC power and supplies the multi-phase AC power to the rotating electric machine. The command value calculator calculates command values for operating the at least one electric power converter. The input voltage determiner determines whether an input voltage of the at least one electric power converter is within a normal operation range. When the input voltage is determined by the input voltage determiner to be outside the normal operation range, the control apparatus switches control to ignore voltage change or current change caused by the reverse input of an external force to the rotating electric machine from a load side or suppress control fluctuation caused by the reverse input of the external force.

Claim (Index 1):
A control apparatus that controls drive of a multi-phase rotating electric machine, the rotating electric machine being configured to output torque to a load during normal operation of the rotating electric machine, wherein operation of the rotating electric machine when an external force is inputted reversely to the rotating electric machine from the load side is defined as being not normal,\n the control apparatus comprising: at least one electric power converter configured to convert, through operation of a plurality of switching elements, DC power into multi-phase AC power and supply the multi-phase AC power to the rotating electric machine; a command value calculator that calculates command values for operating the at least one electric power converter and thereby controlling energization of the rotating electric machine; and an input voltage determiner that determines whether an input voltage of the at least one electric power converter is within a normal operation range, the input voltage being a voltage between a high-potential line and a low-potential line of the at least one electric power converter, the normal operation range being a range of the input voltage during normal operation of the rotating electric machine, wherein the control apparatus is configured to switch control, when the input voltage is determined by the input voltage determiner to be outside the normal operation range, to ignore voltage change or current change caused by the reverse input of an external force to the rotating electric machine from the load side or to suppress control fluctuation caused by the reverse input of the external force.
