摘要： A gas cooktop appliance (10) includes a burner (12A, 12B, 12C, 12D), a gas supply circuit (14) in fluid communication with the burner (12A, 12B, 12C, 12D), and a valve (16A, 16B, 16C, 16D) for controlling an amount of gas supplied to the burner from the gas supply circuit (14). An electrode (18A, 18B, 18C, 18D) is configured to provide an ignition spark (20) and to obtain an ionization current (22). A control system (100) is operably coupled with the valve (16A, 16B, 16C, 16D) and is configured to compare the ionization current (22) to a setting of the valve and modify the amount of gas supplied to the burner when the difference between the ionization current (22) and the setting of the valve is outside a predetermined threshold.

摘要： A method is provided for identifying cookware items (30, 32, 34) placed on top of an induction cooktop (10) having a plurality of coils (20 1 -20 n ). The method includes the following steps: acquire coverage factor information for each coil (20 1 -20 n ) and collect it into a matrix; identify all local maxima in the matrix; find the coordinates of each of the local maxima as follows: when the local maxima is a single coil (20 1 -20 n ), the coordinates are those of the coil center, and when the local maxima is a region of contiguous coils (20 1 -20 n ), the coordinates are those of a centroid of the region; calculate distances from each coil (20 1 -20 n ) to each of the coordinates of the identified local maxima; determine a minimum among the distances; classify the coils (20 1 -20 n ) in clusters, based on the distances from the local maxima; and use the identified coil (20 1 -20 n ) clustering to estimate the position, shape, size, and orientation of the cookware items (30, 32, 34).

摘要： An induction cooking apparatus including a coil beam assembly, an inverter assembly, and a heatsink. The coil beam assembly includes one or more induction coils. The inverter assembly includes a first circuit board that is electrically connected to the induction coil(s) such that the inverter assembly is configured to supply electricity to the induction coil(s). The heatsink has a beam-like structure and is attached to both the coil beam assembly and the inverter assembly. The heatsink is positioned above the inverter assembly and below the coil beam assembly such that the heatsink is the sole support structure for the inverter assembly. A method for assembling the induction cooking apparatus is also described.

摘要： An induction cooking apparatus including a cooktop panel, induction coil, controller, and temperature sensor assembly. A temperature sensor and guiding support are positioned in sliding engagement in an opening in the center of the induction coil where an upper end of the temperature sensor sits above a top surface of the induction coil. The controller includes a first circuit board that supplies electricity to the induction coil. A second circuit board, separate from the first circuit board, is electrically connected to the temperature sensor and includes a cantilevered leaf-spring structure that supports the temperature sensor. The guiding support is a load bearing structure that transmits a biasing force created by deflection of the cantilevered leaf-spring structure to the temperature sensor, which operates to hold the temperature sensor in contact with a lower surface of the cooktop panel.

摘要： A method for identifying cookware (30, 32, 34) on an induction cooktop (10) having coils (20 1- 20 n ), includes the steps: (a) acquire a coverage factor matrix; (b) set a present level at a maximum value of the matrix; (c) count closed iso-level curves corresponding to the present level and save the result; (d) decrease the level by an amount; (e) count closed curves corresponding to the decreased level; (f) when the number of closed curves at the present level is not lower than that from the previous level, update the saved result with the present level; (g) when the number of closed curves at the present level is lower than that from the previous level, keep the previously saved result; (h) repeat steps (d) to (h), until the number decreases; (i) assign coils (20 1 -20 n ) inside the curve to a distinct cluster (40, 42); and (j) use the clustering to estimate a position, shape, size, and orientation of the cookware (30, 32, 34).

摘要： According to the method of controlling a switching converter of this disclosure, the following operations are carried out: :
regulation of the output power to be delivered to the at least one resonant load is obtained adjusting the common switching frequency of all said PWM control signals and the phase displacement of all said PWM control signals, wherein said step of adjusting the phase displacement is carried out by adjusting a time delay between the turning-on of diagonal switches of said two half-bridge switching stages connecting said resonant load, within the same switching period. The phase displacement is carried out until hard-switching working conditions for said half-bridge switching stages are met, and wherein when said hard switching working conditions are met the method further comprises the step of adjusting the common switching frequency of all said PWM control signals to thereby prevent hard-switching working conditions.
The control method of this disclosure is particularly suitable for being used in multi-stage inverters according to this disclosure, comprising more than three half-bridge switching stages.-

摘要： The 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 is 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 mains line voltage.
This drawback may be overcome by discharging purposely the DC-bus during an OFF interval of the QR-converter so as the DC-bus is substantially discharged when a new ON interval of the QR-converter is started.
