Abstract:
A vector control device includes a vector control unit computing an output voltage output from the electric power converter according to vector control based on torque command and flux command and generating a PWM signal for controlling the electric power converter based on the output voltage, a first flux-command generation unit generating a flux command for asynchronous PWM mode, and a second flux-command generation unit generating a flux command for synchronous PWM mode. When an output frequency of the electric power converter is lower than a predetermined value, a flux command generated by the first flux-command generation unit is input to the vector control unit, and when the output frequency of the electric power converter is equal to or higher than a predetermined value, a flux command generated by the second flux-command generation unit is input to the vector control unit.
