Abstract :
Motivation for this paper arises from a need to avoid the premature failure of PWM inverter-fed motor stator winding insulation. This paper investigates the effects of winding leakage, mutual inductance and distributed capacitance on turn-to-turn voltage at high frequency. A high frequency model simulating the turn-to-turn voltage was established. Finally, the simulated results were presented
