Publication number: 20230283193Abstract: A switching converter, such as for an induction cooktop, that can be operated to deliver a power level smaller than the minimum power level for having a soft-switching. Input AC terminals are disconnected from the DC-bus capacitor to prevent it from being charged, so that the DC voltage exhibited by the DC-bus is null or smaller than a minimum nominal value when a next ON time interval T1 begins. The switching converter helps prevent ticking noise.Type: ApplicationFiled: March 1, 2023Publication date: September 7, 2023Applicant: WHIRLPOOL CORPORATIONInventors: Salvatore Baldo, Andrea Gallivanoni, Cristiano Vito Pastore, Andrea Zoppi

Publication number: 20230280040Abstract: Operations such as adding food or flipping or otherwise manipulating food in an item of cookware being heated may be detected by comparing with a threshold the time derivative of a sensed temperature and/or of heating power absorbed by an item of cookware, wherein the heating power is provided by an induction cooktop operated in order to keep constant the temperature value sensed by the sensors coupled to the item of cookware.Type: ApplicationFiled: March 2, 2023Publication date: September 7, 2023Applicant: WHIRLPOOL CORPORATIONInventors: Alessandro Boccotti, Andrea Gallivanoni, Gaia Mannara, Annalisa Pacioni, Davide Parachini, Cristiano Vito Pastore

Publication number: 20230283195Abstract: A ticking noise that can be heard when the QR converter is operated to deliver a power level smaller than the minimum power level for having a soft-switching can be due to the fact that during the OFF interval there is no power delivery and the DC-bus capacitance is charged at the peak of rectified main line voltage. This drawback may be overcome by discharging purposely the DC-bus capacitor during an OFF interval of the QR converter until the DC-bus capacitor is substantially discharged when a new ON interval of the QR converter is started.Type: ApplicationFiled: March 1, 2023Publication date: September 7, 2023Applicant: WHIRLPOOL CORPORATIONInventors: Salvatore Baldo, Andrea Gallivanoni, Cristiano Vito Pastore, Andrea Zoppi
