High Frequency Model of Inverter-fed Induction Motor

Voltage varing Fate dv/dt which is applied to induction motor usually makes unnegligible leakage current and it flows through stator winding and motor frame. This kind of harmonic leakage current makes effect on power source and cuases electromagnetic trouble because the motor frame has earth. Therefore in this study, a high frequency induction motor model is developed and analyze the motor performance to explain the phenomena. Inverter model is also developed and is combined with the motel model to prepare the basis of the high frequency effects on inverter fed induction motor.
