Definitions

the invention relates to a device and a method for controlling or supplying power to induction heating devices of an induction hob, so-called induction coils.
the power supply of these induction heaters via the mains or a mains phase thereof, wherein a filter unit and the filter unit is provided on a rectifier unit with at least one inverter and a DC link.
a rectifier unit with two inverters in the rectifier unit are advantageously connected to a filter unit so that one induction heater is driven or supplied with power per inverter.
Induction generators or devices for cooktops are optimized for two or four induction coils or hobs.
Devices with one or three hotplates are realized by omitting an inverter or by operating a two-circuit cooking zone by means of two-speed converters.
Systems with four cooking zones are realized by parallel construction of two two-unit units. Five or six systems respectively use three two-unit units or a four-unit unit in combination with a two-unit unit.
a generator basically includes the inverters that generate the high frequency and a filter.
Filter and inverter can be constructed on a printed circuit board or separately, but always a converter unit with one or more induction coils, typically two induction coils, permanently associated with a filter unit.
Each filter unit can be connected separately to a mains phase. If fewer phases of the network are available than filter units, the filter units are always connected together on the network side.
a single converter is switched alternately by means of relay switching to a plurality of induction coils or a plurality of heating circuits of an induction coil.
two or more inverters which may also be located in different converter units, can be permanently connected to different partial coils of a multi-circuited induction coil.
the JP 2003-282226 A describes a generic device for controlling induction heating of an induction cooktop with a filter unit, a rectifier unit, a plurality of converters and a DC link.
the structure of the drive for each induction coil of the induction heaters is the same.
the invention has for its object to provide an aforementioned device and a method for power supply or control of induction heating, with which problems of the prior art can be avoided and in particular advantageously an additional induction heater can be controlled with the least possible Effort.
an additional induction heater which is connected behind one of the existing filter units to be provided for a further induction heating device which is to be controlled by the device or the method and to be supplied with power.
a further induction heating device which is to be controlled by the device or the method and to be supplied with power.
the additional converter can be connected without a rectifier to an intermediate circuit of an existing, connected to the filter unit rectifier unit, in particular directly connected. Furthermore, this connection can again be made via switching means similar to the above.
the additional converter without rectifier can be connected via switching means to a plurality of intermediate circuits of a plurality of rectifier units. An alternating power supply of the additional converter via the connection of different intermediate circuits can be carried out according to the same principles as described above for the connection of the additional converter to a filter unit.
the additional converter for the additional induction heater is connected together with a rectifier unit for it between a filter unit and an existing rectifier unit with the inverters.
the additional converter can be connected directly to a connection between the filter unit and rectifier unit.
a switching means for example a relay
the additional converter is connected, as it were, to one or another filter unit via the switching means, depending on the still available power reserve of the filter unit.
the additional converter for the additional induction heating device can in each case be connected to that filter unit which at this moment has a lower power output for its existing induction heating devices, that is to say even a larger power reserve.
additional power to additional heating devices, each having two or more associated induction coils as so-called two-circuit heaters or multi-circuit heaters so that the power comes from an existing first rectifier unit for a first induction coil
the power can come from a pre-described additional converter, which is connected to switching means with one of the intermediate circuits of the existing rectifier units.
the power supply of the second induction coil can come via an additional converter with rectifier unit, which is connected to an existing filter unit.
inverter operated frequency synchronized.
interference noise between the induction heaters can be avoided.
a device 11a is shown for driving induction heating devices 14a to 17a.
These induction heating devices 14a to 17a are part of an induction hob 12a shown in dashed lines, as for example from the above-mentioned WO 2004/014106 A1 is basically known.
the induction heating devices 14a to 17a each have induction coils 14'a to 17a, which are shown schematically, or are formed by these. This realization is no problem for the skilled person.
the device 11a has two filter units 23a and 24a, which are connected to a power grid 21, in particular a two-phase power grid. Although the filter units 23a and 24a are shown together, they may be separate components. Advantageously and usually they are arranged on the same circuit board or in the same housing.
a first rectifier unit 26a is connected on the left filter unit 23a.
This has a rectifier 27a, which feeds two converters 28a and 29a, via an intermediate circuit, not shown, but this is usually done and also emerges from the aforementioned prior art.
the inverter 28a feeds the induction heater 14a and the inverter 29a feeds the induction heater 15a, and the inverters are respectively responsible for the power supply of the induction heaters.
the right filter unit 24a accordingly feeds a second rectifier unit 31a having a rectifier 32a and two inverters 33a and 34a which in turn power the induction heaters 16a and 17a.
the device described corresponds to the state of the art for driving the four induction heating devices 14a to 17a via four inverters 28a, 29a, 33a and 34a.
an additional induction heater 18a with corresponding induction coil 18'a is to be supplied with power in the induction hob 12a, this is difficult in itself. Although it could be connected via a switching means to an output of one of the inverter, but then the other, usually supplied by this inverter induction heater could not be supplied with power.
a switching means 36a is connected to the connections of both rectifier units 26a and 31a with their respective filter unit 23a and 24a, ie behind the filter units.
the switching means 36a can connect to the supply of one of the filter units, depending on the current power requirement situation.
the switching means 36a feeds an additional converter 38a. This in turn ensures the power supply for the additional induction heater 18a.
the switching means 36a is connected to the right filter unit 24a. This means that the total power required by the induction heaters 16a, 17a and 18a may not exceed the total power that the filter unit 24a can provide to a maximum, for example even in the short term.
the above-described power sharing methods are applied between the three induction heaters set by the inverters 33a, 34a and 38a, respectively.
the filter unit 24a is overloaded, it is possible to switch to the possibly still left-hand filter unit 23a.
An additional converter thus basically switches over the switching means to the filter unit or rectifier unit which is more suitable at this moment.
the desired power of each induction heater can be adjusted by the inverter.
Fig. 2 is a modification of the device Fig. 1 shown as a device 11 b.
the additional switching means 36b is no longer connected directly to the filter units 23b and 24b, but to the intermediate circuits, not shown, of the first rectifier unit 26b and the second rectifier unit 31b.
the additional rectifier according to Fig. 1 is no longer necessary because the connection is just made directly to the DC link of the existing rectifier units. Otherwise, the same applies here as before for the function and use of the switching means 36.
the maximum available total power of the rectifier units or the associated DC link must also be taken into account.
Fig. 3 is a further modification of a device 11 c shown, which again essentially that of Fig. 2 corresponds, ie with the additional switching means 36 c connected to the intermediate circuits of the first rectifier unit 26 c and second rectifier unit 31 c. Furthermore, in Fig. 3 the existing induction heater 17c and the corresponding induction coil, the inner part of a two-circuit heater. The outer part surrounding the inner part is formed by the additional induction heater 18c with the corresponding induction coil. This additional induction heater 18c is powered by an additional inverter 38c.
the two induction heaters 17c and 18c form the same hotplate for an induction hob, they are fed from different inverters and, if the additional inverter 38c is connected to the left rectifier unit 26c via the switching means 36c, even across different filter units and different rectifier units.
the distribution of the power can be advantageous in this case, however, since in a two-circuit operation of the two-circuit heater large power is needed and then belonging to the same rectifier unit 31 c induction heater 16c probably not or only with very low power could be operated. Otherwise, the same rules for a power distribution apply as described above.
two additional inverters 38d and 39d are connected to a switching means 36d.
the additional inverter 38d feeds the additional induction heater 18d and the additional converter 39d feeds the additional induction heater 19d.
an induction hob with six induction heating 14d to 19d and thus also six cooking zones can be constructed here.
Both additional induction heaters 18d and 19d can thus be connected via additional inverters 38d and 39d and the switching means 36d to one of the intermediate circuits of the existing rectifier units 26d and 31d. In this respect, performance management is of great importance.
a device 11 e is shown.
two additional switching means 36e and 40e are provided, which are respectively connected to both intermediate circuits of the existing rectifier units 26e and 31 e.
the switching means 36e is connected to an additional converter 38e, which feeds an additional induction heater 18e from the intermediate circuit of one of the rectifier units.
the additional switching means 40e connects the additional inverter 39e to one of the intermediate circuits of the existing rectifier units for supplying power to the additional induction heater 19e.
each of the inverters 38e and 39e for the induction heaters 18e and 19e are connected as needed via the switching means 36e and 40e to one of the intermediate circuits of the existing rectifier units 26e and 31e.
both converters 38e and 39e are connected to the same DC link if this is the set power as well as the power reserves of the relevant rectifier unit.
