Comparison between Matrix Converter and Indirect Matrix Converter.

Three-phase to three-phase power conversion with variable frequency and output voltage amplitude control can be realized with both matrix converter and indirect matrix converter configurations. Even if this two power converters have a different topology, the indirect configuration provides an equivalent circuit widely used to define matrix converter modulation strategies. The equivalence between the states of the two converters is well known but a discussion on indirect matrix converter relationships has never been deeply investigated. This paper discusses the equivalence between the two power converter configurations from a mathematical viewpoint, pointing out the intrinsic characteristics and potentialities of each of them.
