ABSTRACT:
A power supply system for analog computers and the like where reliability and fail-proof performance are paramount. At least two separate power supplies are connected in parallel to a plurality of operational amplifiers contained in separate channels of an analog control system. Isolation diodes are used to prevent a short-circuit in one power supply from being reflected into the other supply and causing loss of both.
