Predictive voltage control with imposed source current waveforms in an indirect matrix converter

In this paper is presented an alternative to generate sinusoidal output voltage waveforms using predictive control in an indirect matrix converter while achieving sinusoidal source currents on the input side. These objectives are accomplished by using a predictive control scheme which calculates the future values of the variables to be controlled in order to choose the converter state that produces the minimal error between them and their references. The proposed predictive method is tested by simulation results, obtaining sinusoidal output voltage and achieving a desired input displacement factor, with a low THD on both source currents and load voltages.
