摘要： A control device that controls an electric motor drive device is configured with a current control portion that determines a voltage command value, a voltage control portion that generates a switching control signal, and a current control period determining portion. The control device is also configured with a voltage control period determining portion that determines a voltage control period, and a control period setting portion. In the control device, the current control period determining portion determines, according to a target torque, the current control period as a value that increases continuously or stepwise as the target torque decreases. Furthermore, the voltage control period determining portion determines, according to a rotating speed, the voltage control period as a value that increases continuously or stepwise as the rotating speed decreases.

摘要： An inverter control section controls the inverter by controlling an armature current in a two-axis orthogonal coordinate system that rotates in synchronization with the rotary electric machine, the armature current being a vector obtained by synthesizing a field current and a drive current extending along respective axes of the orthogonal coordinate system. If it is determined that connection between the DC power source section and the inverter is in a blocked state, the inverter control section executes zero-torque control in which the inverter is controlled such that torque regenerated by the rotary electric machine becomes zero, and executes high-loss control in which the field current is varied so as to increase the armature current while maintaining a torque command provided in the zero-torque control.
