Abstract
An electronic balance control circuit includes an OP-AMP comparator circuit for receiving a command signal and a feedback signal. A positive OP-AMP detector circuit for causing a first buffer trigger circuit to fire a first triac to energize a first output when the command signal is less than the feedback signal, and a negative OP-AMP detector for causing a second buffer trigger circuit to fire a second triac to energize a second output when the command signal is greater than the feedback signal.
