This paper illustrates the application of a method based on the resolution of linear systems to an uncommon inverter switching cell. This study describes the mathematical model of the modulated inverter leg associated at the considered structure. The generalized inverse of a matrix is used to generate the admissible conduction rates. Among the modulation strategies obtained, three specific modulation schemes are proposed and discussed thanks to the generic mathematical standpoint used.
