A method for operating an induction cooking hob including a plurality of inductors in association with induction resonant inverters operating in load-dependent frequency ranges includes a simultaneous activation of inductors, in at least one phase of the control period, independently from their association to one or more overlying cooking utensils but only according to at least partial overlapping of associated operating frequency ranges.

Method for operating an induction cooking hob and cooking hob using such method

A power delivery system and method for an induction cooktop are provided herein. A plurality of inverters are each configured to apply an output power to a plurality of induction coils electrically coupled thereto via corresponding relays. A selected inverter is operable to momentarily idle to enable commutation of a relay connected thereto. An active inverter is operable to increase its output power for the duration in which the selected inverter is idled in order to lessen power fluctuations experienced on a mains line.

Power delivery system for an induction cooktop with multi-output inverters

A household appliance power supply device and method are disclosed. The power supply device comprises a switching converter having an input filtering stage; and a determining means configured to obtain estimation data indicative of the input current that is adsorbed from the a main power input, on the base of the rate of change of the bus voltage across said bus capacitor respectively, during a second switching period. The switching converter further comprises a bus capacitor, electrically connected with at least one output terminal of a rectifying stage, a resonant tank, electrically connected with said bus capacitor, and a switching device electrically connected with said resonant tank, said switching device being operated with a switching cycle having a first switching period, and a second switching period.

Power supply device for a household appliance and an operating method thereof

A method for detecting and compensating the effects of disturbances in controlling induction heating systems by monitoring the temperature of the cooking vessel or its content on the basis of at least one electrical measurement correlated to said temperature. An analysis in time and/or frequency domain of said electrical measurement is carried out in order to detect and compensate the effect of cooking vessel movements and/or mains line voltage fluctuation or similar electrical noises.

Method for detecting and compensating noises in induction heating systems for domestic and professional kitchen and induction heating system using such method

A method for controlling resonant power converters using power transistors, particularly for induction heating systems, comprises a step of assessing the occurrence of non-zero voltage switching or non-zero current switching and a step of adjusting the control accordingly, the assessment of the above occurrence being performed by monitoring at least one electrical parameter correlated to the resonant circuit.
