Abstract

PURPOSE: To prevent an erroneous operation of a temperature control device due to incoming noise or the like by setting a heat sensitive thyristor at the same potential as one terminal of an AC power supply and triggering in next positive half-cycle when a triode AC switch triggers in negative half-cycle.
CONSTITUTION: Since a heat sensitive thyristor 4 is OFF during negative half-cycle of an AC power supply 1 when the temperature of an article to be heated is lower than predetermined temperature, the phase of the power voltage is lead. when the voltage is raised higher than the set value of a zener diode 5, a current is flown through the gate of an auxiliary thyristor 6 via the power supply 1 - resistor 21 - zener diode 5 to cause the auxiliary thyristor to become ON. Thus, a triode AC switch 3 is conducted in a loop of the power supply 1 - heater 2 - the terminal T1 of the triode AC switch 3 - gate - auxiliary thyristor 6 - power supply 1 to thereby supply power to a heater 2. When time constant of a capacitor 42 and a resistor 41 is suitably selected, the auxiliary thyristor 44 is conducted at the beginning of the positive half-cycle to thus conduct the triode AC switch 3 so as to supply a current through the heater.
