<p>The present invention relates to a temperature controller of a heating fiber, which controls the temperature of a heating fiber to be constantly maintained and, more specifically, to a temperature controller of a heating fiber, which allows the heating fiber to be heated at a set temperature without being influenced by the surrounding environment. According to the present invention, the temperature controller comprises: a switching unit for switching the power of a battery to be supplied to the heating fiber or to be blocked; a control unit for controlling switching of the switching unit; and a differential amplifier for detecting or amplifying resistance in accordance with the temperature of the heating fiber, and transmitting the resistance to the control unit. The switching unit comprises: a first transistor for allowing the heating power of the battery to be supplied to the heating fiber by switching operation; and a second transistor for allowing check power to be supplied to the heating fiber by switching operation in a direction opposite to that of the first transistor. The differential amplifier comprises: a detection voltage unit for detecting a heating fiber voltage by the supply of the check power; a standard voltage unit for setting a standard voltage; and an amplification unit which amplifies a difference between a detection voltage of the heating fiber, detected by the detection voltage unit, and the standard voltage, set by the standard voltage unit, and transmits the difference to the control unit.</p> |
