Review of predictive control methods to improve the input current of an indirect matrix converter

The experimental implementation and performance analysis of control techniques applied to an indirect matrix converter are presented here, to improve the input current behaviour under resonances and harmonics distortions. The control strategies are based on model predictive control, which uses the commutation state of the converter in the subsequent sampling time, according to an optimisation algorithm given by a simple cost function and the discrete system model. Experimental results with a laboratory prototype are provided in order to validate the different control schemes, and the effects of a distorted source voltage and filter resonance are analysed.
