The temperature controller circuit is composed of the power supply circuit, temperature detection control circuit and control implementation circuit, and it is shown as the chart. Power supply circuit is composed of the power switch S, power transformer T, bridge rectifier UR, filter capacitors Cl ~ C3, three-terminal voltage regulator integrated circuit IC1, resistor R2 and power indicator LED YL1. Temperature detection control circuit is composed of the temperature detection diode VD1, resistors R3 ~ R1O, operational amplifier integrated circuit IC2 (N1 ~ N3) and the potentiometer RP. Control implementation circuit is composed of the resistors R11, R12, transistor V and thyristor VT.
