Overvoltages caused by the PWM inverter in the stator coils of asynchronous motor

Autor: Ali Mahieddine, El Hadj Ailam, Mohamed Ali Moussa, Mohamed Nadjib Benallal

Publikováno v: 2014 Electric Power Quality and Supply Reliability Conference (PQ).

In our paper, are presented experimental results based on the function of an asynchronous motor (squirrel cage 3 kW) supplied by a frequency converter PWM. The harmonics of the HF signal generate overvoltages with different amplitudes in the stator c
