To gain better velocity modulation function and reduce the switch loss, the PWM voltage usually possesses very high frequency and dv/dt in inverter fed induction motor system. The common mode coupling current in the common mode coupling circuit will come into being inside the motor when this style PWM voltage acts on the winding of induction motor. The common mode coupling current component which crossed the motor bearing will give rise to damage to the bearing. This paper gives a measure… CONTINUE READING
