Abstract
Model-based predictive control is a recent alternative to improve the quality of the output in power converters. In this research, predictive current control is implemented in a voltage source inverter, operating at a variable switching frequency and at fixed switching frequency. Experimental results allowed to verify the effectiveness of the predictive controller, as well as the advantages of the commutation strategies at variable frequency and to fixed frequency. Values such as the percentage of total harmonic distortion (THD) and the absolute error of current allow to demonstrate the superiority of the strategies at fixed frequency in comparison with the classical control.
