PURPOSE: A driver apparatus for deviation forward operation of a digital temperature controller and its method are provided to prevent high increase of a temperature by using a fan during a sustain process. CONSTITUTION: According to the driver apparatus for driving a deviation forward operation, a noise filter(10) removes noise of an external input power supply. A temperature measurement resistor measures a temperature for temperature control. A digital temperature controller(12) maintains and controls the temperature by proportional and integral and differential control. A silicon controlled rectifier(20) realizes power control and temperature control by a control signal from the digital temperature controller. A power converter(16) detects used power by detecting a current and a voltage by the control of the silicon controlled rectifier. A heater(22) heats the temperature measurement resistor through the temperature control of the silicon controlled rectifier. A fan(26) prevents the temperature of the temperature measurement resistor from being increased above a set temperature by the heater. And a motor controller(14) controls to drive the fan.
