To provide a control apparatus of an inverter that achieves both an enhancement of comfort in a vehicle and an enhancement of the starting performance of the vehicle.SOLUTION: A control apparatus 10 of an inverter 2 that controls drive of a traction motor 1 of a vehicle is described. At a time when the vehicle starts moving by the drive of the traction motor 1, the control apparatus executes control processing to set a carrier frequency of the inverter 2 to a low frequency fl within an audible range, and at a time other than when the vehicle starts moving, the control apparatus executes control processing to set the carrier frequency to a high frequency higher than the low frequency fl.SELECTED DRAWING: Figure 1
【課題】車両での快適性の向上と車両の発進性能の向上とを両立するインバータの制御装置を提供する。【解決手段】車両の走行用モータ1の駆動を制御するインバータ2の制御装置10において、走行用モータ1の駆動による車両の発進時に、インバータ2のキャリア周波数を可聴領域の範囲内の低周波数flに設定する制御処理を実行し、発進時以外のときに、キャリア周波数を低周波数flよりも高い高周波数fhに設定する制御処理を実行する。【選択図】図1
