電流 궤환에 의한 인버터 驅動 誘導 電動機의 시스템 安定化에 관한 硏究 = A Study on the stability of inverter induction motor system by current feedback

다국어 초록 (Multilingual Abstract)

In this study, we introduce the concept of idealized induction motor to improve the stability of induction motor systems which move under voltage PWM inverter. The inverter is applied to compensate for the terminal voltage by feeding back the load current of motor.
When the voltage PWM inverter-moved induction motor is used, the content rate of harmonics is increased. But we found that this content rate can be decreased by using the stabilizing circuit. And the wave form of velocity alteration could be improved by compensating for the motor input terminal voltage through positive feed back of load current.
