Abstract

PURPOSE: To shorten the recovery time of a rectification type relay by providing a comparator which compares the input side signal of a semoothing circuit with its output side signal and by generating the output signal of the relay only when this comparator generates its output.
CONSTITUTION: After being rectified, an AC input is smoothed 2 and this smoothing output is compared with a set value so as to generate the output of level detection part 3. Comparator 4 is provided which compares signal (a') obtained by smoothing the input side signal of smoothing circuit 2 of the relay in this constitution at a discharge time constant shorter than that of smoothing circuit 2 with signal (b') obtained by dividing the output side signal of smoothing circuit 2 at a variable dividing ratio, and only when this comparator 4 generates an output, output signals from level detector 3 are used as relay output signals.
