Exact Linearization Nonlinear Neutral-Point Voltage Control for Single-Phase Three-Level NPC Converters Cobreces, Santiago Bordonau Farrerons, José Salaet Pereira, Juan Fernando Bueno, Emilio J.

The control is addressed considering the plant under study, a nonlinear time-variant system. A quasi-exact linearization is applied allowing the application of classic control techniques. The described method is simple, general, and suitable for buck and boost topologies, as well as for inverter or rectifier operating modes under either linear or nonlinear loading. Correct operation is verified under simulated and experimental operation. Postprint (published version) 2009-10 Article Cobreces, S. [et al.].
