Definitions

  • the invention relates to a method for operating an induction heating device according to the preamble of claim 1, a method for pan detection for an induction heating device according to the preamble of claim 9 and an induction heating device according to the preamble of claim 10.
  • Induction cooking appliances or induction cookers are becoming increasingly popular. Advantageous is their high efficiency and the rapid response to a change in the cooking level.
  • the disadvantage is the high price compared to glass ceramic hobs with radiant heaters.
  • Induction cooking appliances usually comprise one or more induction heating devices associated with a respective cooking area with an induction coil which is supplied with an alternating voltage or an alternating current, whereby eddy currents are induced in a cookware to be heated which is magnetically coupled to the induction coil.
  • the eddy currents cause heating of the cookware.
  • the mains input or AC line voltage is usually first rectified by means of a rectifier into a DC supply voltage or DC link voltage and then to generate the high-frequency drive voltage by means of one or more switching means, generally insulated gate bipolar. Transistors (IGBT), processed.
  • IGBT insulated gate bipolar. Transistors
  • a widespread in Europe converter variant forms a half-bridge circuit of two IGBTs, wherein the induction coil and two capacitors, which are connected in series between the intermediate circuit voltage and the reference potential, form a series resonant circuit.
  • the induction coil is connected to a connection to a connection point of the two capacitors and to its other connection to a connection point of the two IGBTs forming the half-bridge.
  • This converter version is powerful and reliable, but relatively expensive due to the two IGBTs required.
  • a variant optimized from a cost point of view uses only one switching means or an IGBT, wherein the induction coil and a capacitor form a parallel resonant circuit. Between the output terminals of the rectifier, parallel to the DC link capacitor, the parallel resonant circuit of induction coil and capacitor and the IGBT are connected in series.
  • this converter variant there is a risk that in unfavorable operating conditions, for example, when using unfavorable cookware, an overload of the components can be caused. This usually leads to a reduced service life of such induction heating devices.
  • the object of the invention is therefore to provide a method for operating an induction heater, a method for pan detection for an induction heater and an induction heater, in which the induction heaters have a converter with only one switching means or an IGBT and the operating conditions change allow a reliable and component-saving operation with high life of the induction heater.
  • the invention achieves this object by a method for operating an induction heater according to claim 1, a method for pan detection for an induction heater according to claim 9 and an induction heater according to claim 10.
  • the inventive method is used to operate an induction heating with an induction coil, a capacitor which is connected in parallel to the induction coil, wherein the induction coil and the capacitor form a parallel resonant circuit, and a controllable switching means, in series with the parallel resonant circuit between one of an AC line voltage generated DC link voltage and a reference potential is looped in and is controlled such that a vibration of the parallel resonant circuit is effected during a heating operation.
  • the maximum value is preferably less than 50V, more preferably less than 10V. This allows a particularly component-preserving and thus low-wear operation of the induction heater, since the switching means is switched on exactly when there is no or only a small voltage at the connection node of the parallel resonant circuit and the switching means.
  • the oscillating circuit is supplied with just enough energy during the charging or charging phase that the voltage at the connecting node of the parallel resonant circuit and the switching means in the subsequent oscillation cycle just swings back to the desired voltage value, ie in the low or high voltage Reversing point has the desired voltage level. If the on-time is set too short, the voltage at the node in the subsequent oscillation cycle is too high at the bottom, causing a current spike when the switch is turned on.
  • the reference voltage is preferably the ground potential.
  • all suitable voltage-resistant switching means can be used as the switching means, in particular, these are high-voltage-proof insulated gate bipolar transistors (IGBTs).
  • IGBTs high-voltage-proof insulated gate bipolar transistors
  • the switch-on time duration is determined or adjusted such that a low-point voltage in subsequent oscillation cycles is equal to the reference voltage. In this case, the switch-on of the switching means is virtually de-energized.
  • the switch-on time duration is increased in comparison with a switch-on time period of a preceding oscillation cycle when the low-point voltage exceeds a predetermined threshold value.
  • a stepwise adjustment or regulation of the low-point voltage can be achieved. If the low point voltage in one oscillation cycle n is too high, this means that too little energy was fed into the resonant circuit in one oscillation cycle n-1, i. the switch-on time was too short.
  • the switch-on period is therefore to be increased, for example, with a predetermined step size. If, in the oscillation cycle n + 1, the low-point voltage again exceeds the threshold value, the on-time is increased again.
  • the on-time can also be reduced from a low point voltage of OV in successive oscillation cycles until, for example, the low point voltage is slightly greater than OV but less than an adjustable threshold. In this way, a dynamic tracking of the switch-on time is possible if the resonant circuit parameters, for example, due to a displacement of a cooking vessel on a hotplate change.
  • the lowest point of the oscillation or of the respective oscillation cycles is determined by derivation or differentiation. Determining a voltage waveform at the connection node of the parallel resonant circuit and the switching means determined. By deriving the low point of the voltage curve or a vibration cycle can be easily determined, since there the value of the derivative is zero.
  • the low-point voltage is compared with a reference voltage and, depending on the result of the comparison, a comparison signal is generated which indicates whether the low-point voltage is greater or less than the reference voltage.
  • the reference voltage is generated as a function of the switching state of the switching means.
  • a cooking vessel is located on a cooking surface or heating zone associated with the induction heater, wherein a cooking vessel is detected when no low points of vibration cycles at the connection node of the parallel resonant circuit and the switching means can be determined in the area of a zero crossing of the mains AC voltage.
  • the damping of the resonant circuit depends strongly on whether a cooking vessel is in a heating zone of the induction heater or not. When a magnetically acting cooking vessel is placed on a cooking surface, the resonant circuit damping increases greatly, because the resonant circuit energy is removed, which is absorbed by the cooking vessel.
  • the DC link voltage decreases so much in the range of a zero crossing of the AC line voltage that no training with detectable low points more. Consequently, if no low points are detectable in the area of the zero crossing of the network, it can be deduced that a cooking vessel is present. This is possible continuously during an active heating operation.
  • the switching means is closed for a short time, whereby an oscillation of the parallel resonant circuit is excited.
  • the number of oscillation cycles occurring is determined by determining and counting low points of the oscillation at a connection node of the parallel resonant circuit and the switching means.
  • the presence of a cooking pot or pot is determined depending on whether the number of oscillation cycles falls below a predefinable threshold.
  • a resonant circuit damping is dependent on whether or not a cooking vessel is located in a heating zone of the induction heating device.
  • the resonant circuit damping increases sharply. In this case, no oscillation and hence no low points of the oscillation are detectable after just a few oscillation cycles or periods. If no cooking vessel is placed on a cooking surface, the vibration and thus also the low points of the vibration is much longer detectable, i. the number of counted or countable low points is much larger compared to the more damped oscillation with a cooking vessel. The number of counted low points can therefore be used as an indicator of the presence of a cooking vessel.

  • an induction coil a capacitor, which is connected in parallel to the induction coil, wherein the induction coil and the capacitor form a parallel resonant circuit, and a controllable switching means, which is looped in series with the parallel resonant circuit between a DC link voltage and a reference voltage and is driven such that during a heating operation, a vibration of the parallel resonant circuit is effected.
