ABSTRACT: This project proposes a novel dual-input matrix
converter (DIMC) which is used to integrate the output of the wind energy to a
power grid. The proposed matrix converter is developed based on the traditional
indirect matrix converter under reverse power flow operation mode, but with its
six-switch voltage source converter replaced by a nine-switch configuration followed by the current source
inverter (CSI). Matrix electric power conversion topologies and their switch
functions are flexible and are used for specific applications. With the
additional three switches, the proposed DIMC can provide six input terminals,
which make it possible to integrate two independent AC sources from two
independent wind turbines into a single grid tied power electronics interface.
Commanded currents can be extracted from the two input sources to the grid. The
proposed PI control and modulation schemes guaranteed sinusoidal input and
output waveforms as well as reduced THD. The simulation results are provided to
validate the effectiveness of the proposed control and modulation schemes for
the proposed converter.
