Circuit structure for operating consumers on a variable distribution voltage source of current uses consumers' own sources of voltage to form constant sources of current as operational amplifiers

摘要

Each consumer is assigned its own source of current supplied from a higher order source of current. Connected to the consumers in series and switched on and off, the consumers' own sources of voltage form constant sources of current as first (1), second (13) and third (25) operational amplifiers. Consumers include first (11), second (23) and third (35) relays.
