Multiphase matrix converter for power systems application

Abstract

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 high speed, multiphase generator and power grid 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 a new FACTS device, based on straight forward energy conversion.
