An assessment of predictive current control applied to the direct matrix converter based on SiC-MOSFET bidirectional switches

Abstract

Matrix converters are devices that allow the management of bidirectional flows of energy with reduced size, increased useful life and high efficiency in ac-ac energy conversion systems. In this paper the experimental results obtained after the application of a predictive current control technique for a SiC-MOSFET based direct matrix converter feeding an isolated load are presented. The results obtained are compared with a scheme based on IGBT technology in terms of power consumption and total harmonic distortion.
