Abstract

The system is intended to provide an isolated power supply for an electrical load. It contains a generator for producing a supply signal, and a transmission path having two separate branch elements. The first branch element is designed for transmission of the supply signal (S1) in the forward direction, and the second branch element is designed for transmission of the supply signal in the backward direction, so that this results in a closed circuit for the supply signal. The two branch elements contain means for isolation. The load can be supplied by the supply signal with an electrical power of at most 100 mW.
