Abstract: A temperature control circuit for two heating devices respectively provided with a heater and a sensing wire. The sensing wires' ends are respectively connected to a diode. The two diodes' polarity is opposite to that of the sensing wires' connecting ends. Another ends of the sensing wires are connected to a capacitor to form a resistor-capacitor circuit. The heater wires are connected to a diode respectively and then a bi-directional thyristor. The two diodes' polarity is opposite to that of the heater wires' connecting ends. Thereby, the heater wires can be heated up respectively by the positive and negative half-periods of alternating current. When phase shifts occur because of the heater wires' temperature change, the sensing wires can control the bi-directional thyristor via a controller so that the positive or negative half-period are not triggered. Therefore, the heater wires' heating temperatures can be controlled individually.
