Direct Predictive Current-Error Vector Control for a Direct Matrix Converter

This paper proposes a novel control strategy for matrix converters that is coined “direct predictive current-error vector control.” The proposed control method retains the advantageous features of both a modulation scheme and of a predictive-based controller. The result is a controller that is capable of good dynamic performance and steady-state response with fixed switching frequency operation. Control of load and input currents of a direct matrix converter using the proposed method is demonstrated in this paper by simulation and experimental results.
