Abstract: 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.

Abstract: 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.

Abstract: 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.
