Predictive Direct Power Control Drive System of Doubly-Fed Induction Machine Fed by Indirect Matrix Converters

This paper presents a novel predictive Direct Power Control (DPC) for Doubly-Fed Induction Machine (DFIM) based on Indirect Matrix Converter (IMC), which is characterized by a simple structure, minimal power ripple and constant switching frequency. Nowadays, the control strategies based on predictive methods have proved their efficiency to improve drive systems capabilities. So, in this paper, one of the best predictive methods that has recently been suggested for DFIM drive systems, is applied to Indirect Matrix Converter. The purpose of this combination is modifying the control parameters and size volume reduction of drive system structure which it is difficult to achieve in conventional systems based on VSI converters
