    ABSTRACT: An overview of the matrix converter and standard protection strategies is presented for an understanding of the matrix converter and its currently implemented protection strategies. New protection methods are then proposed for downstream faults to reduce their severity and to buy enough time to fully protect both the matrix converter and sensitive loads. The goal of implementing new output protection strategies is to be able to utilize the matrix converter in future distributed generation applications. The proposed methods are based on the addition of a standard protective relay and circuit breaker combination at the output of the matrix converter along with generator neutral grounding resistance and a zero voltage output command. Simulation and hardware testing results are then presented in order to verify that the new methods will protect the matrix converter and downstream loads while adding additional selectivity and diagnostic capabilities

    ABSTRACT: The US Army Research Laboratory is currently studying the application of matrix converters to supply battlefield loads using variable speed diesel generators by utilizing a matrix converter to provide a bidirectional, three-phase to three-phase, direct AC to AC link between a diesel generator and load. This allows more efficient and economical operation of the diesel generators. A very brief overview of the matrix converter and standard protection strategies is presented, followed by new output protection strategies. The new output protection strategies account for the presence of the third harmonic component in the matrix converter output. Simulations are then presented to prove that the added output protection is capable of protecting a matrix converter and load when used in battlefield applications while adding increased selectivity and diagnostic capabilities.
