Abstract
A kind of temperature controlling device of heating element and method thereof detect the actual temperature of heating body of the heating element, and calculate the descending gradient and frequency of temperature based on the detected actual temperature. The norm signal is formed based on the actual temperature, descending gradient and frequency of the temperature to control the switch power as to achieve the split second control for the electric power of the heating element.
