Matrix Converters: Challenges and Solutions

The advantages of high efficiency and reliability, as well as weight and loss benefits, make matrix converters an attractive option for AC/AC power conversion. This paper reviews the existing AC/AC converter solutions in mining industry and provides a detailed discussion of the main features and techniques associated with matrix converters. The paper explains the fundamental difficulties in satisfying the load side and the supply side performance objectives, simultaneously. The paper then discusses and compares several control options for matrix converters, including the recently proposed Comprehensive control. The latter shows advantages over other options and can be recommended for demanding industry applications. Findings of the paper are supported by detailed simulations.
