ABSTRACT:
An inverter (1) for feeding electric power into a utility grid (7) or into a load is described. The inverter (1) contains two direct voltage inputs (2, 3), one first intermediate circuit (8) connected thereto and comprising two series connected capacitors (C1, C2) that are connected together at a ground terminal (14), two alternating voltage outputs (5, 6) of which one at least is provided with a grid choke (L1) and one bridge section (10). In accordance with the invention, a second intermediate circuit (9) that is devised at least for selectively boosting the direct voltage and is intended for supplying the bridge section (10) with positive and negative voltage is interposed between the first intermediate circuit (8) and the bridge section (10).
