INVERTER DEVICE FOR ELECTRIC VEHICLE

摘要

An inverter device for an electric vehicle includes an inverter circuit 2 that controls an electric motor 3 connected to a wheel 8 via a connecting member and a control unit 20 that controls torque of the electric motor 3. The control unit 20 includes a current control unit 23 that executes control so that a q-axis current command iq* for the electric motor 3 matches a current flowing through the electric motor 3, and a limiter unit 21 that puts limitations so that a magnitude of the q-axis current command iq* does not become equal to or smaller than a preset predetermined value.
