ABSTRACT:
A heating system including a power supply and a heating element for conducting a current from the power supply. A temperature sensing device is adopted to detect a temperature of the heating element, and a switch is connected in a circuit containing the power supply and the heating element to switch the current on or off. Further, a microprocessor produces a pulse-width-modulated signal as a function of the detected temperature, where the pulse-width-modulated signal drives the switch.
