Several control strategies were investigated for the proposed application of the MC taking under consideration stated requirements of the power system, necessary symmetry of connector and optional MC work without interfering with the power system. A matrix three phases converter is a very simple structure incorporating nine 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 control scheme for the matrix converter, based on an “area” approach, which is easy applicable using any simple microprocessor controller. The scheme is then applied to manage matrix converter working as an interconnection between two power systems.
