Abstract

PURPOSE: To establish the pulse width output regulator simple in the circuit constitution, by comparing the deviation between the saw tooth wave signal in DC bias with the pulse width output regulator and driving the contact of the regulator output from the result.
CONSTITUTION: The saw tooth wave production circuit 6 consisting of the integration circuit 7 and comparator A2 outputs the saw tooth wave signal V3 having the bias value VD setting the neutral zone and the peak value Vp in proportion to the proportional band of the regulator. The said valves Vp and VD of the said signal V3 can arbitrarily be set with the comparizon voltage fed to the comparator A2, and the period T is set with the resistor RA and capacitor CA. The error signal ε between the signal V3 and the regulator is compared at the comparator 3 and the output controls the relay 5 for ON and OFF via the relay drive circuit 4.
