A generic method of Pulse Width Modulation applied to three-phase 3-Level T-type NPC inverter
Résumé
This paper illustrates the application of a solvingmethod of linear systems to a multilevel inverter. This study appliesa generic pulsewidth modulation (PWM) method to a multileveltopology. This method finally highlights some specific modulationschemes. First, the study describes the mathematical model of theinverter leg. The leg is made of three level T-type structure. Themodel is extended to the three-phase inverter. The generalized in-verse is used to generate the solution set of the conduction rates.Among the modulation strategies possible, three specific modula-tion schemes are proposed. The modulation schemes are applied tosimulate a PWM three-phase inverter. Finally, some experimentalresults complete the analysis.
