Supplying current to load from at least two current sources

摘要

The method involves detecting signals dependent on the load currents (I1,I2) of each current source. The measured load current dependent signals are fed into a common bus line (BL) via couplers (R1,R2). The signal parameters occurring at the couplers, esp. their voltage drops, are evaluated to determine whether the parameters are larger or smaller than the mean of all signal parameters. The current sources (SV1, SV2) are controlled according to the deviations.
