Predictive control of an indirect matrix converter operating at fixed switching frequency and unbalanced AC-supply

摘要

This paper proposes a predictive control technique for an indirect matrix converter. The proposed control strategy gives sinusoidal waveforms at both the input and output of the converter without any weighting factor in the cost function and, at the same time, giving operation at a fixed switching frequency. Simulation results with an unbalanced ac-supply validate the proposed method under both steady state and transient conditions.
