ABSTRACT:
An inverter having a plurality of inverter bridges which operate in parallel and whose output voltage is summed by way of a transformer. The transformer has a number of primary windings and associated secondary windings which correspond to the number of inverter bridges. Each inverter bridge is connected on the output side to a primary winding. The secondary windings are connected in series to sum the output voltages. The transformer has a center tap which is grounded by a ground connection. The suppression of in-phase or common-mode interference currents flowing by the ground connection and the interference voltages associated therewith is achieved by dividing the secondary windings into a first and second identical partial secondary winding. The partial secondary windings are connected to one another in the center tap in such a way that the common-mode currents and voltages induced in the partial secondary windings mutually cancel.
