Abstract

Provided is a system for sensing temperature in an induction heating system. The system includes an induction element, a susceptor element, and a temperature sensor circuit in thermal contact with the susceptor element. The temperature sensor circuit includes a capacitor having a capacitance value equal to C and an inductor having an inductance value equal to L. A resonant frequency of the temperature sensor circuit changes based on a temperature of the susceptor element and the induction element is electromagnetically coupled to the temperature sensor. The resonant frequency of the temperature sensor circuit is equal to ½π√LC.
