ABSTRACT:
Power amplifier for the feed of an inductive load having switched transistors is composed of a bridge circuit, wherein a plurality of series circuits of transistors with free running diodes are connected parallel in each bridge arm. An inductor is arranged in the connection of each series circuit to the inductive load, this inductor being current-compensated such that it has an effective inductance only when a non-uniform division of current occurs in a bridge arm. The transistors and diodes are linearly arranged.
