Abstract: A method for controlling a heating operation of an induction cooktop includes generating a direct current (DC) power from an alternating current (AC) power source. The DC power is supplied to a first resonant inverter and a second resonant inverter via a power supply bus. A switching frequency of each of the first resonant inverter and the second resonant inverter is controlled and in response to the switching frequency supplied to a plurality of induction coils of the resonant inverters, an electromagnetic field is generated. A selective tuning operation of the first resonant inverter or the second resonant inverter includes controlling a connection of a capacitor to either the first resonant inverter or the second resonant inverter.

Abstract: A method for calibrating an induction cooking device includes capturing image data representing a cooking vessel and processing the image data to identify one or more features. The method further includes comparing the image data representing the cooking vessel to a library of stored image data of calibrated cookware. In response to identifying stored image data in the library that matches the one or more features, the method accesses preconfigured calibration data and configures the operation of the induction cooking device based on the preconfigured calibration data.

Abstract: The present disclosure relates to an induction cooktop. The induction cooktop comprises a ceramic cooking surface in connection with a housing. A plurality of inductors is disposed in the housing and each of the inductors is in communication with an automatic control system. The automatic control system is configured to check for the presence of a cooking pan on the cooktop in order to prevent the inductors from activating in the absence of the cooking pan. The automatic control system is activated upon receiving an activation command.

Abstract: An induction cooktop includes a cooktop surface, a plurality of power delivery coils in an array beneath the cooktop surface, a cooking article detector, a light source directed toward the cooktop surface, and a controller. The controller receives a signal from the cooking article detector including size and position information for at least one detected cooking article on the cooktop surface and determines that a detected position of the detected cooking article does not correlate with a preferred position of the cooking article with respect to at least one of the plurality of power delivery coils. The controller then presents an indication, via the light source, of the preferred position of the detected cooking article on at least one of the detected cooking article and the cooktop surface.
