Zusammenfassung:A photovoltaic solar inverter is disclosed with network filter without inductance connectable to the AC network. The inverter comprises: a power module to convert a DC voltage of entry into a three -phase output voltage of output; An AC/AC three -phase transformer to adapt the three -phase voltage output voltage of the power module to the three acasic AC voltage of the AC network, which has an inductance "l2". The Ac/AC three -phase transformer includes a winding on the network side with an equivalent inductance "l1 "; A "C" capacitor, connected to the winding side of the three -phase transformer AC/AC. The equivalent inductance "l1" (L-) of the AC/AC transformer, condenser "c" (-c-) and inductance "l2 " (-(-(- L) From the AC network form a high frequency filter type "LCL", eliminating the inductances provided only to form the LCL filter. Also a network filter without inductance with "LLCL" typology.

El inversor comprende: un módulo de potencia para convertir una tensión DC de entrada en una tensión trifásica AC de salida; un transformador trifásico AC/AC para adaptar la tensión trifásica AC de salida del módulo de potencia a la tensión trifásica AC de la red AC, la cual tiene una inductancia "L2". El transformador trifásico AC/AC comprende un devanado en el lado de red con una inductancia equivalente "L1"; un condensador "C", conectado al devanado del lado de red del transformador trifásico AC/AC. La inductancia equivalente "L1" (L-) del transformador AC/AC, el condensador "C" (-C-) y la inductancia "L2" (-L) de la red AC forman un filtro de alta frecuencia tipo "LCL", eliminando las inductancias proporcionadas únicamente para formar el filtro LCL. También un filtro de red sin inductancia con tipología "LLCL".
