Integration of Renewable Energy Sources Using Matrix Converter.

      Аннотация: Dual-Input Matrix Converter (DIMC) design is proposed to integrate wind energy and solar photo-voltaic system to power a dc grid. The proposed DIMC is based on the traditional indirect matrix converter with additional switches in order to comprise more than one input. With this nine-switch configuration in the rectifier stage it’s possible to integrate two independent sources into single power electronic interface. The PV system is interfaced with DIMC through a six-step inverter in order to obtain three phase ac so that it can be processed by DIMC. Under different modes, DIMC works as AC-AC with single source or dual source. A control algorithm has been proposed to select the renewable source that generates enough power to supply the grid. In case demand is more, the energy from both the sources can also be utilized with the help to DIMC.
