Abstract
An adaptive temperature control circuit includes a first circuit for producing an error signal representing the difference between a preset temperature and an actual temperature and a second circuit coupled to the first circuit for producing a pulse width modulated output signal having a frequency greater than one hertz, wherein the width of the pulses is proportional to the error signal.
