Definitions

Induction heating is used in the field of induction cooking, particularly in induction ovens, induction cooktops and induction hobs.
induction hob induction heating coils are located under a cooking hob surface for heating cooking pans made (or including portions) of electrically ferromagnetic material placed on the cooking hob surface.
the envelope of the AC current flowing through the induction heating coil has an amplitude that depends on the actuation frequency (the lower the actuation frequency, the higher the amplitude thereof), it is not possible to known a priori whether a selected actuation frequency corresponds to a current flowing through the induction heating coil that is lower than the maximum current or not.
the induction cooking system 100 comprises a (e.g ., glass-ceramic) cooking surface 165.
a number of induction coils 135 are placed underneath the cooking surface 165.
the current Ic flowing through the induction heating coil 135 is alternatively sourced by the IGBT 212h (when the IGBT 212h is on and the IGBT 2121 is off) and drained by the IGBT 2121 (when the IGBT 212h is off and the IGBT 2121 is on).
an inverter circuit 140 of the quasi-resonant type such as the one illustrated in Figure 2B , comprising a rectifier 250 (for example, a bridge rectifier) adapted to rectify the input AC voltage Vin, a quasi-resonant circuit 260 (for example comprising an inductor in parallel to a capacitor) corresponding to the resonant section 210 of the half-bridge inverter circuit 140 of Figure 2A , and a switching circuit 270 (for example comprising a single transistor) corresponding to the switching section 205 of the half-bridge inverter circuit 140 of Figure 2A .
a rectifier 250 for example, a bridge rectifier
a quasi-resonant circuit 260 for example comprising an inductor in parallel to a capacitor
switching circuit 270 for example comprising a single transistor
actuation frequency is varied within a single half-wave.
the actuation frequency can be dynamically adjusted to provide for a temperature control which precisely reflects a temperature setting selected by the user of the induction cooking system 100, in the following the procedure for boiling detection in accordance with the present invention will be explained in detail.
the measurements described herein can be performed also at a time when the power delivery is turned off, such as when the boiling condition is reached and hence less power is required as compared with the phase of heating-up the cooking site.
the induction coils can be operated intermittently so as to maintain a boiling condition, wherein the above measurements can be effected at a chosen repetition rate, such as every 30s, so as to provide for a continuous monitoring of the pot.
a power delivery cycle upon reaching the boiling condition is illustrated in Figure 13 .
