Abstract
Induction cooktops and operational methods are provided herein. A method of determining material composition of cookware on an induction cooktop can include determining that a piece of cookware is on the induction cooktop, inducing a current within the piece of cookware with an induction coil of the induction cooktop, and obtaining a peak induction coil current, a smoothed input line current, and a phase shift of current flowing in the induction coil. The method can further include comparing the peak induction coil current, the smoothed input line current, and the phase shift each to a set of predetermined ranges, and determining candidate material compositions for the cookware based on the comparing of each of the peak induction coil current, the smoothed input line current, and the phase shift.
