Patent ID: 8023288

Claim:
An inverter for a grounded direct voltage source, for converting the direct voltage into an alternating voltage with a DC-DC converter and a pulse inverter that is supplied by said DC-DC converter, said DC-DC converter being configured to be an oscillating circuit inverter and comprising a series resonant oscillating circuit, wherein said DC-DC converter is configured to be a series-compensated oscillating circuit inverter with a choke and a series-connected capacitor array comprising two or more oscillating circuit capacitors, a rectifier bridge branch including two diodes, is connected to each of the oscillating circuit capacitors, said rectifier bridge branch being connected with its positive or its negative pole to output side intermediate circuit capacitors which are connected in series so that said DC-DC converter delivers at least two bipolar output voltages such that the DC-DC converter is connected to a pulse inverter by a divided voltage intermediate circuit that is supplied from the oscillating circuit inverter.
