Abstract
A control device that includes an AC voltage command determination section that determines an AC voltage command value, which is a command value of the AC voltage supplied from the DC/AC conversion section to the AC electric motor, on the basis of a target torque of the AC electric motor and a rotational speed of the AC electric motor; and a system voltage command determination section that determines a system voltage command value, which is a command value of the system voltage generated by the voltage conversion section, on the basis of the AC voltage command value and the system voltage.
Claims9
A control device for an electric motor drive device including a voltage conversion section that converts a power source voltage from a DC power source to generate a desired system voltage and a DC/AC conversion section that converts the system voltage into an AC voltage to supply the resulting AC voltage to an AC electric motor, the control device comprising:
- an AC voltage command determination section that determines an AC voltage command value, which is a command value of the AC voltage supplied from the DC/AC conversion section to the AC electric motor, on the basis of a target torque of the AC electric motor and a rotational speed of the AC electric motor;
- and
- a system voltage command determination section that determines a system voltage command value, which is a command value of the system voltage generated by the voltage conversion section, on the basis of the AC voltage command value and the system voltage.
