ABSTRACT:
A power supply includes a direct converter provided in the form of a two-phase or three-phase bridge circuit. The bridge branche of the direct converter includes a serial connection of any number of identical two-terminal networks, each having the following characteristics: The two-terminal networks each have at least one switching state, in which their terminal voltage takes on positive values independent of the magnitude and polarity of the terminal current; the two-terminal networks each have at least one switching state, in which their terminal voltage takes on negative values independent of the magnitude and polarity of the terminal current; the two-terminal networks have at least one internal energy store.
