ABSTRACT:
The control of the operation of an electric circuit element, such as an electrochemical cell, is performed by positive feedback servocircuitry developing an error signal or inherent noise component, and having algebraic computing capability for developing the compensating control. Current follower circuitry is arranged for developing a potential proportional to the current drawn by the electric circuit element to be controlled. A portion of this potential is algebraically combined with the externally applied operating electric wave. The inherent noise component of the control circuitry is sensed by a high pass filter and an ac-dc converting circuit and thereafter integrated for generating a slowly varying potential for determining the portion of the potential derived by sensing the current. The two potentials are applied to a conventional multiplying circuit and the product potential combined with the operating wave.
