Abstract
This paper gives an overview to voltage-controlled matrix
converter commutation. Conventional converter systems with explicit sign
measurement circuits that were necessary for the commutation in the past
are discussed. New operation methods eliminating these extra measuring
circuits are presented. The paper explains the new methods. Advantages
and disadvantages of different approaches are discussed. The robustness
of the new methods against disturbance is proved and measurements on a
5.5-kW matrix converter system are shown
