Title
(EN) MULTILEVEL HYBRID INVERTER AND OPERATING METHOD
(FR) ONDULEUR HYBRIDE MULTI-NIVEAU ET PROCÉDÉ DE FONCTIONNEMENT
Abstract
(EN) An inverter comprises a first boost apparatus (112), a second boost apparatus (114), a first half-cycle switching network (104) coupled to the first boost apparatus (112), wherein the first half-cycle switching network is configured such that a first three-level conductive path is formed when a voltage at a dc source is greater than an instantaneous value of a voltage at an output of the inverter and a first five-level conductive path is formed when the instantaneous value of the voltage at the output of inverter is greater than the voltage at the dc source.
(FR) L'invention porte sur un onduleur qui comprend un premier appareil d'amplification (112), un second appareil d'amplification (114), un premier réseau de commutation à demi-cycle (104) couplé au premier dispositif d'amplification (112), dans lequel le premier réseau de commutation à demi-cycle est configuré de telle sorte qu'un premier chemin conducteur à trois niveaux est formé lorsqu'une tension au niveau d'une source à courant continu (CC) est supérieure à une valeur instantanée d'une tension au niveau d'une sortie de l'onduleur et un premier chemin conducteur à cinq niveaux est formé lorsque la valeur instantanée de la tension au niveau de la sortie d'onduleur est supérieure à la tension au niveau de la source CC.
