Grid integration of AC and DC energy resources using multi-input nine switch matrix converter

High penetration of Grid by various energy resources leads to intermittent voltage and frequency variations. To smoothen out these variations and to integrate energy resources to the grid, this paper proposes a multi-input matrix converter topology to integrate the ac and dc energy resources to the grid. This matrix converter is based on the indirect matrix converter operating in the reverse boost mode. The reverse boost mode is preferred over the forward buck mode, since most of the energy resources have voltages lower than the grid voltage. The proposed matrix converter consists of nine switches providing six input terminals, there by a three phase AC source and three DC sources can be integrated to the grid. This proposed scheme guarantees sinusoidal input and output current waveforms and proper power dispatch to the grid.
