Abstract

PURPOSE: To make a switching noise low and scrupulously control a temperature, by bringing the switch means to which the heater and the power source have been connected in series, to zero-cross switching by the pulse output by the time series pulse transducer.
CONSTITUTION: The resistor R1 is connected in series with the temperature detecting thermister TH, and the bridge is formed by the resistors R2 and R3. An output of this bridge is amplified by the differential input amplifier A, and it is digitized by the A/D converter ADC. Combination of the A/D converter and the address recorder of the pattern generator PG functions as a temperature level discrimination device, and the zero-cross detector ZCD is a synchronizing signal generating circuit for detecting the passing time point of zero-voltage of the supply voltage and outputting a synchronizing signal to the supply voltage. Also, the shift register SR which operates as a time series pulse transducer makes the output pulse of the counter C a set input, inputs the output signal of the generator PG, and serially outputs by making the output of the detector ZCD a clock.
