초록

PWM-VSI based ac-drives have high nonlinearity due to dead-time in the inverter and the voltage drop across the switching devices. In this paper, we introduced a new nonlinear model of PWM-VSl including parastic capacitor and also showed validity of the model by circuit simulations and experiments. Furthermore, we proposed an on-line identification algorithm for the uncertain model parameters.
