CORRECTING CONVERTER FOR AUTOMATIC CONTROL SYSTEM Russian patent published in 1994 - IPC

FIELD: control equipment. SUBSTANCE: correcting converter for automatic control system has common memory capacitor, clock pulse master oscillator, circular counter, pulse formers, commutator and unit of correcting capacitors. Converter has two keys operating in antiphase. During first half-cycle of controlling voltage second key is closed and value of voltage memorized in advance is commutated to memory capacitor. During second half-cycle first key is closed and memorization of input signal of converter is accomplished. EFFECT: enhanced reliability of correction of static and dynamic errors. 2 dwg
