A new concept of application of multiphase matrix converter in power systems

A matrix NxM multi phase converter is a very simple structure incorporating NxM bi-directional switches, able to convert input voltages into output voltages of any shape and frequency. However, commutation problems and complicated control algorithms keep it from being utilized on a large scale. This paper shows a new field of application of the matrix converter, witch is working as a connection device between or as an interconnection device within power system. The task performed by this connection is a control of power flow and power flow oscillations dumping. The device can be viewed as new FACS device, based on straight forward energy conversion.
