Abstract :
This paper aims to present investigation results related to PWM-VSI frequency converters performance under nonideal voltage supply conditions. Besides computational analysis using a proper model in the Saber simulator, practical studies are also given. The later uses a commercial type of converter and a programmable power quality disturbances source. Using both the theoretical and practical way of considering different items of nonideal supply, different situations are simulated to estimate the equipment behavior. The paper focuses the characteristic and noncharacteristic harmonic spectrum generation for both the input current and the output voltage
