Design of logic connection controllers for three-phase voltage-source converters

A particular analysis of dependencies between the switch states and the resulting converted electrical quantities is detailed in this paper. By using a nonlinear inversion of these relations, we deduce a connection controller which enables the proper control of modulated electrical variables. This method is then used to control a three-phase voltage-source controlled-current PWM rectifier. The generality of the proposed method points out the unification of this design to matrix converters of any dimension.
