  "textContent": "The present invention discloses a photovoltaic solar inverter with an AC grid filter without inductance connectable to the AC grid. The inverter comprises: a power module for converting a DC input voltage into a three-phase AC output voltage; a three-phase AC/AC transformer for adapting the three-phase AC output voltage of the power module to the three-phase AC voltage of the AC grid, which has an inductance \"L2\". The three-phase AC/AC transformer comprises a winding on the grid side with an equivalent inductance \"L1\"; a capacitor \"C\", connected to the winding of the grid side of the three-phase AC/AC transformer. The equivalent inductance \"L1\" (L-) of the AC/AC transformer, the capacitor \"C\" (-C-) and the inductance \"L2\" (-L) of the AC grid form a high frequency \"LCL\" filter, eliminating the inductances provided only for forming the LCL filter. The invention also discloses an AC grid filter without inductance with an \"LLCL\" typology.",
