Three-phase PWM VSI Induction Motor Drives: VSI power transmission optimization by adopting a series-Line Termination Net

摘要

In the paper, a lumped parameters while accurate high-frequency model of AC motors is introduced, together with measurement methods for the identification of the parameter values. Secondary effects, affecting the response to 3Φ-VSI voltage modulation are also evidenced. Accordingly, LTN design rules are analytically reported as a function of AC motor model parameters. The LTN design criteria are experimentally tested on a standard 55kW rated IM drive. Cancellation of motor overvoltage is finally achieved together with efficiency.
