Abstract :
In this paper a protection circuit is presented by which the matrix converter is protected using a free wheeling path available any time. This conducts the load current if necessary, so that the parts of the inverter can not be damaged. With this feature, no complicated commutation strategy and control method are necessary to operate the matrix converter safely. Other advantages arise because a buffer capacitor is not needed for protection. So the size, the weight and the costs of the inverter are reduced.
