摘要： The invention relates to a method for operating an induction cooktop (1). The induction cooktop (1) comprises at least two cooking zones (4, 6). The method comprises
- providing for selection by a user at least two different preprogrammed cooking schemes (B, G, F, S, W) for controlling a respective cooking zone (4, 6) according to a predefined heating course,
- assigning different priority values to each cooking scheme (B, G, F, S, W), and
- upon selection of a respective cooking scheme (B, G, F, S, W) for at least two cooking zones (4, 6) diverting heating power (P) to the respective cooking zones (4, 6) in dependence on the respective priority value assigned.-

摘要： Method to control a quasi-resonant inverter (13) in an induction cooking appliance (1) provided with induction heating coil (4). The quasi-resonant inverter (13) comprises a switching device (21) electrically connected to the induction heating coil (4) by a node (20) having a first voltage (VC(t)) which is indicative of the voltage across the power switching device (21). The method comprising the steps of: providing to the switching device (21) an enabling signal (K1) comprising a plurality of pulses, in order to switch-on and switch-off said switching device (21) for a switch-on period (tON) and a switch-off period (tOFF), determining a second voltage (VCmin) indicative of the minimum value of the first voltage (VC(t)) during the switch-off period (tOFF), regulating the switch-off period (tOFF) based on the second voltage (VCmin), and regulating the enabling signal (K1) based on the regulated switch-off period (tOFF).

摘要： There is described an induction cooking hob (1) having a support surface (3) for carrying a load (4) on a cooking zone (5), a plurality of induction coils (6), a load detection unit configured to sense by means of the induction coils (6) a presence of the load (4) in the vicinity of one or more induction coils (6) and a control and power unit operatively connected to the plurality of induction coils (6) and configured to selectively power the one or more induction coils (6). The load detection unit is configured to sense by means of the induction coils (6) a movement of the load (4) away from the cooking zone (5) and to send a start signal about the movement of the load (4) away from the cooking zone (5) to the control and power unit. The control and power unit is configured to determine a command signal in dependence of the start signal about the movement of the load (4) away from the cooking zone (5) and to execute the command signal and to continue to selectively power the one or more induction coils (6) so as to maintain the cooking zone unvaried.
