Abstract
An unfolding bridge includes a half-bridge with a first input terminal, a second input terminal, and an output terminal, wherein the half-bridge includes a first bridge switch connected between the first input terminal and the output terminal and a second bridge switch connected between the second input terminal and the output terminal. The unfolding bridge also includes a further half-bridge which includes a first further bridge switch connected between the first input terminal and a further output terminal and a second further bridge switch connected between the second input terminal and the further output terminal. A switch controller for operation of the bridge switches is designed such that a connection of the output terminals with the input terminals via the bridge switches is reversed at a zero crossing of an alternating current flowing at the output terminals. In a current path between the input terminals via the first bridge switch, the output terminals, and the second further bridge switch, and in a current path between the input terminals, via the first further bridge switch (S5), the output terminals, and the second bridge switch, at least one reverse voltage compensator is arranged. The reverse voltage compensator is configured to shift the electrical potential of the respective input terminal with respect to the respective output terminal, between which the reverse voltage compensator is arranged, by a compensation voltage dropped across the reverse voltage compensator, and thereby compensates for a reverse voltage that is oriented against the flow of current in the current path in which the reverse voltage compensator is arranged.
