Abstract
Matrix converter is an alternative topology for a solid state frequency changer without any reactive elements like inductors and capacitors. One of the major obstacles of this topology is the complex commutation of the bi directional switches in absence of natural free wheeling path for the inductive currents. A detailed study has been made here to understand the limitations and possible improvement of the existing current commutation techniques in this paper. A universal and synchronous commutation scheme for all the IGBTs is devised so that commutation can smoothly take place as and when required within the minimum possible time depending on the switching time of the IGBT used. The different aspects of this commutation are verified through MATLB simulink. Possibility of step less current commutation is explored.
