Implementation of an electrical micro-grid through matrix converters connected in parallel

The matrix converter (MC) arouses a growing interest because it provides many advantages. On the other hand, the association of these converters in parallel makes the operation of the system operation more reliable and offers the possibility of creating electrical micro-grids. This article presents a parallel association of MCs by droop parallelization technique, which allows the control of several parallel MCs without needing communication between them. This configuration also offers the possibility to achieve an even load sharing. The obtained results demonstrate the feasibility of this technique.
