▎ 摘  要

NOVELTY - A graphene-production installation comprises a primary signal generator providing a rectangular wave-type signal with adjustable frequency and duty factor, and a module taking over the primary signal and providing, at its output, push-pull rectangular waves forming the control signal of a power final stage, the optical separation of signals being carried out in the modules containing some integrated circuits of optocoupler type, and the amplification of signals up to values of current voltage and intensity necessary to control the final stage being carried out in some modules based on special integrated circuits of metal oxide semiconductor FET OSFET driver-type. USE - Installation is used for quickly producing graphene by electrochemical graphite exfoliation.
