Definitions

  • the invention relates to a method for supplying power to an induction heating device and to an arrangement for supplying power to an induction heating device.
  • Such induction heating devices are used for example as induction coils in induction hobs.
  • induction hobs There is a desire for ever higher performance, in particular cooking operations of larger amounts of liquid, such as pasta water to be able to perform quickly.
  • the cause of the strong effects of the harmonics or, in particular, of the third harmonic lies essentially in the fact that the permeability of the magnetic components in the frequency converter changes with the amplitude of the inductor current flowing through the induction coil.
  • the permeability of ferrites or the like which are used in an induction coil for field guidance, and those of the pot material decreases.
  • the invention has for its object to provide an initially mentioned method and a suitable arrangement with which problems of the prior art can be avoided and in particular reduced without changing the operating frequency at higher power at induction heaters network interference or distortion of power consumption from the supply network can be.
  • a frequency converter is provided with switchable switching means.
  • An operating frequency of this switching means or of the frequency converter remains the same as seen in the course of a half-wave of the AC supply voltage across this half-wave.
  • a pulse width of the control of the switching means or of the frequency converter is changed in the course of a half-wave in a first basic embodiment of the invention. This is done by making a pulse width of a first switching means shorter and a pulse width of another second switching means longer by the half-time of a half-wave. In the second half of the half-wave, the pulse widths are again changed so that they are the same length again until the end of the half-wave.
  • the sum of the pulse widths (G1, G2) remains the same.
  • the change may be unbalanced at half time.
  • a change in the pulse widths is carried out symmetrically at half-time.
  • a frequency converter or the power supply for the induction heating device may have a series resonant circuit. This consists of an induction coil for power transmission, resonant circuit capacitors and a half-bridge with switchable switching means. Such series resonant circuits are basically known for induction heating devices.
  • the change in the pulse widths can be 10% to 40%.
  • Particularly advantageous pulse widths are changed a maximum of 25%, so shortened or extended.
  • both pulse widths are shortened in all or in two existing in a series resonant circuit switching means such that the dead times are extended in between. This also takes place in the course of a half-wave, whereby the dead times become longer until the half-time of the half-wave and then shorter again. In these dead times none of the switching means is driven.
  • a change in the dead times is advantageously at a maximum of 100%, ie a maximum of doubling the dead times between the shortest dead time and the longest dead time. Particularly advantageously, the maximum change is somewhat lower, for example at 50% to 80%.
  • the power at the induction coil can be reduced somewhat to reduce harmonics and thus reduce network perturbations.
  • a shortening of the switch-on times or pulse widths of the switching means takes place, as well as the extension of the dead times, advantageously symmetrically to the half-time of the half-wave. So a uniform control and power generation is possible.
  • a change of a pulse width or a dead time over a mains half-wave takes place as evenly as possible or distributed.
  • a distribution may be such that the change of the pulse width or the dead time substantially corresponds to a sinusoidal curve.
  • An aforementioned arrangement thus has a frequency converter with a resonant circuit which is constructed from the induction coil, resonant circuit capacitors and a half-bridge with switchable switching means. Furthermore, a drive device for the switching means is provided, wherein the operating frequency or the switch-on times of the switching means can be influenced. In particular, so that the pulse widths or the dead times can be changed as mentioned above, wherein the operating frequency is equal and a pulse width shortened or a dead time is extended.
  • FIG. 2 an arrangement or circuit arrangement 11 according to the invention is shown.
  • a controller 13 controls a frequency converter 15 on with two switching means T 1 and T 2 , for example transistors. These form together with a DC link capacitor C 2 and resonant circuit capacitors C s the drive for the induction coil L.
  • the operating frequency for the switching means T 1 and T 2 and thus the frequency converter 15 is mainly specified.
  • the pulse widths G and the dead times H are given.
  • the induction coil L is used in an induction heating device or a heating device for an induction hob, then even more than 3 kW or 3.2 kW are possible, for example 3.5 kW to 3.7 or even 4 kW. Thus, stronger induction hobs can be built for faster parboiling or higher power transmission.
  • the effort for the control of the pulse width G and the dead times H of the frequency converter 15 and the switching means T 1 and T 2 is not particularly high. In particular, if their courses are given fixed or controlled by a control process, the effort is limited because you can work with predetermined progressions.
  • Fig. 3 are in a diagram, the pulse widths G1 and G2 and the dead times H1 and H2 of the transistors T1 and T2 after Fig. 2 at a time near or at the net zero crossing. It can be seen from this that both the pulse widths G1 and G2 take the same length. Likewise, the intermediate dead times H1 and H2 are also the same length at this time.
  • Fig. 4 are the pulse widths changed according to the aforementioned first basic embodiment of the invention. This means that with the same dead times H1 and H2, the pulse widths at transistor T1, ie G1, have become shorter, in this case shortened by about 25% near the peak of a network half-wave.
  • the pulse widths G2 on the transistor T2 have been extended by about 25%.
  • the change in pulse width G1 is as out Fig. 6 can be seen, in turn, itself a sinusoidal curve or has a sinusoidal course.
  • the minimum pulse width G1 is found at the middle or high point of a network half-wave.
  • the course G2, which is not shown, results from mirroring the profile for G1 on a line which runs horizontally through the maximum values for G1 in such a way that the sum (G1 + G2) is always constant.
  • Fig. 5 is shown according to the second basic embodiment of the invention, as deviating from Fig. 4 Although the pulse widths G1 and G2 remain the same, but the dead times H1 and H2 are changed in between.
  • the dead times H1 and H2, ie before the respective pulse width G1 and G2, are compared to Fig. 3 extended by about 60%.
  • the schematic for H1 from Fig. 6 and at the same time is the one for H2.
  • both basic embodiments of the invention can be used together.
  • the change in the pulse width or the dead time should be as analog or mirror-symmetrical as possible or in small steps over a mains half-wave.
  • the formation of harmonics can be reduced or avoided, and on the other hand, it is possible to avoid noise generation as a result of resulting jumps in performance.
