Abstract
The disclosure relates to an inverter comprising at least two controllable load thyristors. One diode each is connected in antiparallel fashion with each load thyristor, which diode is a component of a commutation installation for the corresponding load thyristor. The commutation installation manifests two LC-series oscillatory circuits, which are dimensioned for two different load currents. There is present for each LC-series oscillatory circuit one pair each of commutation thyristors. The two commutation thyristors of one of the two pairs, respectively, are alternately ignited such that, during the commutation of the load thyristors the commutation current can flow in a low impedance circuit.
