ARCP soft-switching technique in matrix converters

Abstract

An alternative concept used to avoid the need for staggered switching in matrix converters is discussed. The features of the auxiliary resonant commutated pole (ARCP) soft switching technique are used to reduce the number of active switches and gate drives in comparison to conventional matrix converter technology, avoid commutation voltage spikes, and reduce switching losses. Three different ARCP matrix converters are reviewed and their operational boundaries are discussed. The ARCPMC technology is critically evaluated with respect to a potential industrial application.
