Reduced Harmonic Pollution: Intelligent Switching Strategy for Matrix Converter

Abstract

This paper proposes a neural-network current-regulated switching strategy for a matrix converter induction motor drive system. In this paper, the design and implementation of the induction motor system has been investigated. This paper has provided a systematic and analytic approach for designing a high performance matrix converter induction motor drive system. All the control algorithms, which include switching strategy, current regulation, are executed by a digital signal processor TMS320C6711. By using this new switching strategy, the current harmonics of the system are effectively reduced. Several experimental results are shown to validate the theoretical analysis.
