Abstract
(EN)
An inverter includes a transformer that includes a first winding, a second winding, and a third winding, a DC-AC inverter electrically coupled to the first winding of the transformer, a cycloconverter electrically coupled to the second winding of the transformer, an active filter electrically coupled to the third winding of the transformer. The DC-AC inverter is adapted to convert the input DC waveform to an AC waveform delivered to the transformer at the first winding. The cycloconverter is adapted to convert an AC waveform received at the second winding of the transformer to the output AC waveform having a grid frequency of the AC grid. The active filter is adapted to sink and source power with one or more energy storage devices based on a mismatch in power between the DC source and the AC grid.

L'invention concerne un onduleur qui comprend un transformateur qui comprend un premier enroulement, un deuxième enroulement et un troisième enroulement, un convertisseur CC-CA couplé électriquement au premier enroulement du transformateur, un cycloconvertisseur couplé électriquement au deuxième enroulement du transformateur, un filtre actif couplé électriquement au troisième enroulement du transformateur. Le convertisseur CC-CA est conçu pour convertir la forme d'onde de courant continu (CC) d'entrée en une forme d'onde de courant alternatif (CA) fournie au transformateur au niveau du premier enroulement. Le cycloconvertisseur est conçu pour convertir une forme d'onde de courant alternatif reçue au niveau du deuxième enroulement du transformateur en forme d'onde de courant alternatif de sortie ayant une fréquence de réseau du réseau à courant alternatif. Le filtre actif est conçu pour baisser et fournir la puissance avec un ou plusieurs dispositifs de stockage d'énergie sur la base d'un décalage de puissance entre la source de courant continu et le réseau à courant alternatif.
