モータ駆動装置
Document Type and Number:
Japanese Patent JP7363702
Kind Code:
B2
Abstract:
To reliably change a carrier frequency when a request torque to a motor increases.SOLUTION: A PCU 14 drives a MG 12 as a power source of a movable body by supplying a driving signal modulated according to a carrier frequency. A prediction unit realized by a motor driving control ECU 18 predicts a request torque to the MG 12. A control unit realized by the motor driving control ECU 18 changes the carrier frequency of the PCU 14 when the prediction unit predicts that the request torque to the MG 12 increases.SELECTED DRAWING: Figure 1
