Control scheme for a multiphase matrix converter EUROCON2009

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. The paper concentrates on the development of a control algorithm for a multiphase matrix converter, which can fulfill all requirements imposed by the proposed application in power systems where sinusoidal shape of the voltage is important. The proposed algorithm is then tested using Matlab Simulink software and optimized for an application in digital controller.
