Description

Introduction and state of the art

The invention relates to a device for supplying at least one consumer with electrical energy or for providing electrical power for at least one consumer.

For many applications, a regulated electrical power supply is necessary. In particular, in the regulation of the supply of LED lights in the vehicle are special requirements to be met.

The LEDs to be supplied are usually in series, rarely parallel connected and are typically powered by a power source. This regulated power source is powered by a power source, typically the board network of a car.

In this case, the problem arises that the regulation of the current source leads to a considerable loss of power within the current source circuit. This has the consequences that in the case of a monolithic integrated circuit (IC) integration additional IC areas are necessary in order not to exceed the critical temperature for the respective semiconductor. At the same time, special measures for cooling in the housing of the power source may be required.

Object of the invention

It is the object of the invention to minimize the resulting from a regulation of the LED current through the power source supplying power loss for the power source itself, thereby significantly reducing the cost of IC area and the housing complexity.

This object is achieved by means of a device according to claim 1. Individual embodiments of the invention are the subject of the dependent claims.

Description of the basic invention

The basic idea of the invention is not only to regulate the current, but also to determine the location at which the power loss is obtained by the regulation of the current, by a further control parameter specifying this location of the additional power loss.

The invention is based on the recognition that basically a transistor, which is the regulating transistor of a current source, can be considered in the broadest sense as an adjustable resistor. If this transistor has a mean resistance, then a maximum of power drops across the transistor.

It has been recognized in the invention that therefore an operating range can be defined in which this transistor can be replaced by another second transistor, which is followed by an external resistor. This second transistor then regulates the current, whereby a part of the control power dissipation does not drop in the second transistor itself, but in the external resistor. Thus, the integrated circuit heats up less, since the heating power is obtained outside of the housing in the said external resistance. If a current is required, which has a transistor resistance below the sum of the on-resistance of the second transistor and the external Resistance requires, so again takes over the first transistor, the scheme.

This quite simple principle can be generalized insofar as the current within two current paths is regulated by two parameters in each case such that the sum of the currents in the two current paths correlates with a first parameter and the distribution of the power loss is linked to a second additional parameter , This is the basic idea of the invention.

Of course, the principle can also be applied to more than two current paths. In that case, two- as well as multi-dimensionally can be regulated between the current paths.

• einer als IC ausgeführten Regelschaltung mit einem Eingang, über den der Regelschaltung elektrische Energie zuführbar ist, und mindestens einem ersten Ausgang und einem zweiten Ausgang, über die ein Verbraucher von der Regelschaltung mit elektrischer Energie versorgbar ist bzw. über den die Regelschaltung elektrische Leistung für einen Verbraucher zur Verfügung stellt,
• mindestens einem außerhalb des ICs angeordneten, externen Widertand zur außerhalb des ICs erfolgenden Abgabe von potentieller elektrischer Verlustleistung, wobei einerseits der externe Widerstand mit dem zweiten Ausgang der Regelschaltung verbunden ist und andererseits an den externen Widerstand der Verbraucher anschließbar ist,
• wobei der Sollwert der von der Regelschaltung zu regelnden elektrischen Leistung des Verbrauchers vorgebbar ist und
• wobei die Aufteilung der elektrischen Energie für den Verbraucher bzw. der für diesen zur Verfügung zu stellenden elektrischen Leistung auf die mindestens zwei Ausgänge der Regelschaltung von dieser in Abhängigkeit von mindestens einem Aufteilungsparameter steuerbar ist, der der Regelschaltung zuführbar oder der in der Regelschaltung ermittelbar ist.

According to the invention, therefore, the device for supplying at least one consumer with electrical energy or for providing electrical power for at least one consumer provided with

• a running as IC control circuit having an input via which the control circuit electrical energy can be supplied, and at least a first output and a second output via which a consumer of the control circuit with electrical energy is supplied or via the control circuit electrical power for a Provides consumers,
• at least one outside of the IC arranged, external Widerertand for taking place outside the ICs of potential electrical power loss, on the one hand, the external resistor is connected to the second output of the control circuit and on the other hand connected to the external resistance of the consumer,
• wherein the desired value of the regulated by the control circuit electrical power of the consumer is predetermined, and
• wherein the distribution of the electrical energy for the consumer or for this to be made available electrical power to the at least two outputs of the control circuit of this in dependence is controllable by at least one distribution parameter, which can be supplied to the control circuit or which can be determined in the control circuit.

As regards the essential approach according to the invention, it should be mentioned that potential power losses, which can occur in the control circuit, are converted via an external resistor or other consumer in the form of heat, which is then released to the environment. Thus, the control circuit itself, which is designed as an IC, protected from thermal overloads. For this purpose, the control circuit supplies to the consumer via at least two paths the "energy" or power demanded by the consumer. One of these two paths is as low as possible, so connected substantially lossless to the control circuit, namely via the above-mentioned first output of the control circuit, while the second power transmission path has the external resistor. By means of two regulator modules, these two power paths are now controlled accordingly, with the electric power being transported from the control circuit to the load exclusively via the first output up to a first limit value. In each regulator module, power loss is also generated in the form of heat to an extent that is of the magnitude of the electrical power to be provided to the consumer. Depending on the operating point in which the at least one driver of a controller module is located, this generates more or less heat. Thus, if the driver were to enter an operating range due to an increased power requirement of the consumer, generating more power dissipation which could affect the IC in the form of heat, the next regulator module will be added to the consumer for additional power delivery.

The distribution of the available electrical power to the controller modules is dependent on the distribution parameters.

The inventive approach is thus contrary to those in the prior art Known method in which to prevent overheating of driver transistors of the load or a load to be supplied power is divided symmetrically or uniformly on several drivers, as for example in EP-A-2,196,887 is described.

In the following, the supply of a single consumer by means of two current sources, which feed into two current paths is described for simplicity. The skilled person will easily be able to extend this basic idea to three or more current paths.

The following reference numbers refer to the drawing.

It is therefore a device for the regulated supply of at least one consumer 11 with electrical energy by a control circuit 10. For the sake of simplicity, it is assumed that the control circuit 10 has at least four terminals 1, 2, 3, 4. A connection 2 is, for example, the ground connection and the reference potential of the control circuit 10 according to the invention, which is part of the device according to the invention. An exemplary consumer 11 has two supply terminals 5, 6. The terminals 5, 6 of the consumer 11 are connected to an output 3 and the ground terminal 2 of the control circuit 10. The control circuit 10 is supplied from a regulated or unregulated energy source 7 at least via its supply voltage terminal 1 and the ground terminal 2 with electrical energy. The second output of the control circuit 4 is electrically connected via a second external resistor R ₄ to a first terminal 5 of the load 11. In this case, the consumer 11 may also be an almost arbitrary electrical network of several consumers who are part of the consumer 11. For example, it may be in parts or in whole to a series and / or parallel connection of LEDs. It is only important that the supply of at least a portion of the consumer via the terminals 5, 6 takes place.

In any case, the consumer 11 must have a common reference potential 2 with the control circuit 10 and the power source 7. This connection can be done electrically directly or indirectly via another consumer or another consumer network. For example, the second terminal 6 of the load 11 may be connected directly to the ground terminal 2 of the control circuit 10.

Of course, it is possible that in the direct connection between the first output 3 of the control circuit 10 and the first terminal of the consumer 5 instead of a direct connection, a connection via a first external resistor R ₃ exists. For the inventive idea, it is only essential that this first external resistor R _{3 has} a different value than the second external resistor R ₄ , since only then a regulation of the location of the seizure of the control power loss is possible to some extent. Of course, it makes sense and expedient if one of the external resistors R ₃ , R _{4 has} a value of zero ohms, which in reality corresponds to a value that is very slightly different from zero. In general, such a connection is simply realized as a direct connection, which corresponds for example to a resistance of a few mOhms.

The resistors R ₃ , R ₄ can then be regarded as unequal, if, depending on the material of the resistors, the latter by more than 1% or better more than 2% or better more than 5% or better more than 10% or better more than 25% or better, more than 50% or better more than 100%. Particularly preferred are lead resistances between the first output 3 of the control circuit 10 and the second terminal of the load 6 of less than 10 ohms or better less than 5 ohms or better less than 2 ohms or better less than 1 ohms or better less than 100 mohms. Such low resistors may generally be considered to have a value of near zero ohms within the meaning of this disclosure.

The consumer 11 is now supplied with the sum of the two output currents I3 + I4. So that the control circuit 10 can perform its actual core task, namely the regulation of the current through the load 11, it is obvious that the sum of the output currents I ₃ + I ₄ at the outputs 3, 4 of the control circuit 10 must be regulated. This sum of the output currents I ₃ + I ₄ must therefore be formed within the control circuit as an actual value. This actual value I ₃ + I ₄ is then compared in the control circuit with a setpoint I _sum , which is predetermined. Both currents I _3, I ₄ are then adjusted accordingly in case of deviations between the sum of the output currents I ₃ + I ₄ and the target value I _sum. In the simplest case, this "corresponding" readjustment is done, for example, by a proportional control in which the two currents I ₃ , I _{4 of} the two outputs 3, 4 are readjusted by an equal factor. Of course, matching the setpoint value I _sum with the predetermined summation current I ₃ + I ₄ may also include more complicated functions than the simple affine mapping described above. It is important that these can be described at least temporarily by a bijective, strictly monotonically increasing function between the desired value I _soll and the current sum I ₃ + I ₄ . In this case, the setpoint I _sum can be preset externally or fixed in the control _circuit 10 as an internal reference _current I _{ref_int} . Of course, for example, the conversion of these quantities by analog or digital computing circuits into other parameters such as voltages before comparison possible. This said specification of the setpoint value I _sum can be set externally, for example, by a reference _current I _{ref_ext} or a reference _resistor R _ref . With a programmed specification, for example, a value can be written into a register by a data interface ST, whereupon a digital-to-analog converter ADC generates the setpoint. In the prior art manifold methods are known for this, so that a further embodiment is not necessary here.

The second essential controllable parameter is the distribution of the sum current I ₃ + I ₄ to the output currents I ₃ , I ₄ . Since their sum I ₃ + I ₄ yes is determined by the said setpoint I _sum , only the ratio of the distribution between these currents I ₃ , I _{4 is} determined by at least one control parameter. This is referred to below as the division parameter V _p . This division parameter V _p can be determined according to various aspects. In the simplest case, this is specified from the outside via an interface. For example, this can be done again via a data interface ST and another register or via a PWM interface, wherein the duty cycle, for example, the division _parameter V _p or one of the aforementioned analog values I _{ref_ext} again. Much better, however, is the determination of the distribution parameter Vp within the control circuit 10 itself. For this purpose, the control circuit typically has a suitable component which performs this determination of the distribution parameter Vp.

In order to determine this division parameter Vp, it initially makes sense to record essential operating parameters of the control circuit 10. This collection does not necessarily have to be permanent. It may be provided for certain operating parameters predetermined times. The measurements can be carried out cyclically or with the aid of a band-limited measuring trigger signal. Then, if the signal has certain conditions, eg. B. fulfilled a zero crossing, a measurement takes place. The latter methodology has the advantage that it is possible that the requirements of electromagnetic compatibility can be observed. However, this depends on the specific application. As meaningful measured variables are a measurement of the output current I ₃ , I _{4 of} the control circuit 10 and / or a measurement of the output voltage U ₃ , U _{4 of} the control circuit 10 and / or a measurement of the output power P ₃ , P _{4 of} the control circuit 10 and the measurement of operating temperatures T exposed. The latter can be measured, for example, in the control circuit 10 itself and / or in parts of the control circuit 10 and / or in the vicinity of the control circuit 10 and / or in the vicinity of a resistor R ₃ , R ₄ and / or in the vicinity of a load 11 become. One or more of these values may then be determined by analog and / or digital calculation said division parameter V _{p be} transformed. Of course, a multi-dimensional control, which regulates both the current sum I ₃ + I ₄ and the current distribution between the output currents I ₃ , I ₄ , makes sense, since due to the measurements in particular faulty states can be detected, which for example to shutdown the control circuit by switching off one or more outputs 3, 4 can lead. In this respect it makes sense that not only the current values of these measured values, but also their past values and past values for the setpoint of the current _sum I _sum and the distribution parameter V _{p are used} for the calculation of the current setpoint values for the current _sum I _sum and the distribution parameter Vp become. These past values may be temporarily stored in a suitable analog or digital memory. For example, the analog memories may be a low-pass filter or a sample-and-hold circuit.

All these measured parameters as well as the course of the stored values as well as their temporally simple and higher derivatives and values derived therefrom can each be compared with nominal values.

The device therefore comprises a component, typically a regulator RG, which compares one of the measured values or an intermediate stored reading or a value derived therefrom with an associated setpoint. The comparison is made by the regulator RG in such a way that the controller checks whether said measured value is smaller than the desired value or greater than the desired value. Of course, it makes sense in some cases for the controller to check whether the measured value is equal to a setpoint. This means that the measured value must lie within a tolerance band around the setpoint. It is therefore more of a target band. Of course, then it makes no sense to evaluate these measured values simultaneously as larger or smaller. As measured values for such a comparison, for example, one of the output currents I ₃ , I ₄ , I ₈ or one of the output voltages U ₃ , U ₄ , U ₈ or one of the output powers P ₃ , P ₄ , P ₈ or the sum of all or one Part of the output currents I ₃ + I ₄ , I ₃ + I ₄ + I ₈ or the sum of all or part of the output powers P ₃ + P ₄ , P ₃ + P ₄ + P ₈ or the operating voltage provided by the power source 7 available U _b or the temperature T of the control circuit 10, the temperature T of a portion of the control circuit 10 or the temperature T in the vicinity of the control circuit 10 or the temperature T in the vicinity of at least one consumer 11 or the temperature T in the vicinity of at least one external resistor R ₃ , R ₄ , R ₈ or the temperature T in a coolant or a cooling medium near a resistor R ₃ , R ₄ , R ₈ or a cached value of these values or a variable derived from these values and / or their cached values become.

It has been shown that it already leads to good results if the distribution parameter Vp is the operating voltage U _b or correlates with it. However, it is also conceivable, as a division parameter Vp one of the output currents I ₃ , I ₄ or one of the output voltages U ₃ , U ₄ or one of the output powers P ₃ , P ₄ or the sum of all or part of the output currents I ₃ + I ₄ or the sum of all or part of the output powers P ₃ + P ₄ or the temperature T of the control circuit 10 or the temperature T of a part of the control circuit 10 or the temperature T in the vicinity of the control circuit 10 or the temperature T in the vicinity of a consumer 11 or the temperature T in the vicinity of a resistance R ₃ , R ₄ or the temperature T of a coolant or cooling medium in the vicinity of a resistor R ₃ , R ₄ to use.

In addition, it is also possible, the sum of the output currents I ₃ + I ₄ as a function of one of the output voltages U ₃ , U ₄ or in dependence on one of the output powers P ₃ , P ₄ or in dependence on the sum of the output powers P ₃ + P ₄ or as a function of the temperature T of the control circuit 10 or the temperature T of a portion of the control circuit 10 or the temperature T in the vicinity of the control circuit 10 or the temperature T in the vicinity of a consumer 11 or the temperature T in the vicinity a resistor R ₃ , R ₄ to regulate. Instead of the aforementioned values, alternatively or in addition, stored values of these values and / or variables derived from these values or the operating voltage U _{b can also be used} for the regulation.

As already mentioned, the existing measured values open up the possibility of using them for error detection. Therefore, a device according to the invention not only has components for making these measurements and producing therefrom the said control signals I _soll , Vp, but preferably, but not necessarily, also via a component having the function of error monitoring. This outputs at least one error signal S _stat , which can signal an error. Such an error signal S _stat may also be the content of a register or a bit, which is connected via a digital interface, for. B. a data interface ST, can be read and its value is generated by said component. An analogue signaling via special lines is of course also possible.

Of particular importance is that this component should also be able to receive error messages from other systems that are not part of the control circuit. Thus, the component should preferably be able to be linked to the error signal of another device according to the invention or another device not according to the invention. This makes it possible, for example, for a fault on a module consisting of control circuit and consumers to be able to switch off all modules connected by chaining. It is particularly advantageous if this chaining is done, for example, by means of a wired-or circuit and a pull-up resistor of the error signal S _stat .

1. a) ein "Open-Fehler", bei dem eine Unterbrechung oder signifikante Einschränkung des Stromflusses durch einen Verbraucher erkannt wird, und
2. b) ein Kurzschluss, bei dem ein Verbraucher überbrückt ist oder einen massiv abgesenkten Innenwiderstand aufweist.

As error modes, which should be particularly preferred to be recognized

1. a) an "open fault" which detects a disruption or significant limitation of the flow of current through a consumer, and
2. b) a short circuit in which a consumer is bridged or has a massively lowered internal resistance.

A characteristic for an "open error" may be, for example, an output current I ₃ , I ₄ which is less than 10% or 20% or 30% or 40% or 50% of a predetermined target or expected value. Here, a value of less than 30% has been found to be particularly advantageous.

As a feature for a short circuit, an output voltage U ₃ , U ₄ can be used which is smaller than a predetermined desired value at at least one of the outputs 3, 4 of the control circuit 10. In the case of a power supply for an LED chain, this setpoint depends on the number of LEDs. For example, it may have a value of 0.5V or 0.1V or 1.5V but other values as well. Incidentally, in the case of an LED circuit, it makes sense if at least one of the resistors R ₃ , R _{4 has} a value of zero ohms or almost zero ohms. This is to be interpreted as having a value of less than 10 ohms or better less than 5 ohms or better less than 2 ohms or better less than 1 ohms or better less than 100 milliohms.

If now such an error from externally by means of signaling or by measurement or by deviation from a setpoint or setpoint range or a predetermined time course or course range of one of the previously discussed parameters and / or one of the previously described control variables and / or derived from these size detected by a component of the control circuit 10, so there is a possible measure that can take an optional control within the control circuit 10 in that the power supply to at least one consumer 11 is reduced or adjusted in the form of the output by the control circuit 10 to this energy.

A particular form of self-diagnosis of the device according to the invention can take place in that one of the current branches, for example the second terminal 4 of the control circuit 10 is not supplied with power and the voltage at this branch, in this example the second output voltage U ₄ , is measured. As a result, the state of an LED chain acting as a consumer 11 can be determined more reliably. However, such a measurement represents a disturbance of the operation. Therefore, this measurement, if any, only temporarily and typically only with a certain minimum time interval and, for example, periodically. A possible self-diagnosis in the form of error detection is therefore at least for a possible error only at certain times and not continuously.

Of course, it is conceivable to use a plurality of control circuits 10 according to the invention for example for RGB light control. For this example, three LED chains in red, green and blue are needed. In this exemplary embodiment, each of these LED chains is powered by a respective device according to the invention with energy. For setting the correct color, it is therefore useful to combine this triple-control circuit with a color sensor MF for this purpose. This typically provides three actual values with which the respective current _sums I _{sum_r} , I _{sum_g} and I _{sum_b} can be _readjusted . Three values can then be specified as an external setpoint, which are converted by a computer into the setpoints I _{sum_r} , I _{sum_g} and I _{sum_b} , depending on the color model used. Of course, the direct specification of the setpoints by an external wiring and / or by means of programming is conceivable. Such an external wiring can be done for example by reference _currents I _{ref_ext_1} , I _{ref_ext_2} , I _{ref_ext_3} , which are impressed via external resistors R _{ref_1} , R _{ref_2} , R _{ref_3} .

Finally, it should be mentioned at this point that, with a suitable embodiment of the external resistor R ₃ , R ₄ , R _{4_1} , R _{4_ 2} , R _{4_ 3} , R _8, it is possible to allow at this operating temperature, which is far above the operating temperatures lie, which are allowed for semiconductors and thus a realization of the control circuit 10 according to the invention as an integrated circuit. Also, the external resistor R ₃ , R ₄ , R _{4_1} , R _{4_2} , R _{4_3} , R _{8 may be} mounted at a location other than the control _circuit 10. This makes it possible, for example, by a suitable thermal insulation between external resistor R ₃ , R ₄ , R _{4_1} , R _{4_2} , R _{4_3} , R ₈ and control _circuit 10 to protect them from excessive temperature _load . The resistor thus acts as a kind of electrical heat sink relative to the system, which makes the character of the invention particularly clear. It is therefore a feature of an appropriate form of the invention that an external resistor R _3, R _4, R _8, R _{4_1,} R _{4_2,} R _{4_3} mounted or in such a spatial distance from the control circuit 10 is thermally otherwise isolated so that on reaching the maximum intended operating temperature T _{R of} the respective external resistance R ₃ , R ₄ , R ₈ , R _{4_1} , R _{4_2} , R _{4_3,} the temperature of the control _circuit 10 in the best case by not more than 10 ° C or worse not more than 20 ° C or worse not more than 40 ° C or worse not more than 80 ° C is increased.

On the other hand, cooling is particularly effective when the temperature difference between the external resistor and its cooling, such as a coolant or heat sink, is maximized. This can be done by maximizing the allowable operating temperature of the external resistor. It is therefore a feature of one embodiment of the invention, when an external resistor R ₃ , R ₄ , R ₈ , R _{4_1} , R _{4_2} , R _{4_3} in a specification-compliant operating state of the control _circuit 10, a temperature of T _R of greater than 150 ° C or better than 200 ° C, or better, greater than 250 ° C, or better, greater than 350 ° C, or better, greater than 450 ° C. In this context, it is conceivable, for example, to carry out the cooling by liquid metal, that is, for example, lead or tin, etc. In this case, the heat of fusion can be exploited if the loads are only for a short time. The device is therefore able to successfully control very large peak loads, which distinguishes it significantly from the prior art.

Description of embodiments of the invention

The following figures represent only a few possible configurations of a device according to the invention. The possibilities according to the invention will become apparent from the foregoing description and the claims.

Fig. 1 shows an exemplary inventive control circuit 10. It has the two outputs 3, 4 and for each of these outputs 3, 4 an associated current source IS ₃ , IS ₄ , which is controlled by a regulator RG. The current of the first current source IS ₃ is passed directly into the first terminal 5 of the consumer 11, in this case an LED chain. The current of the second current source IS ₄ is passed through the resistor R ₄ and generates there a voltage drop. The output voltages U ₃ , U ₄ are detected by measuring devices MU ₃ , MU ₄ and fed to the controller RG as a measured value. Likewise, the currents I ₃ , I ₄ are detected by two further measuring devices MI ₃ , MI ₄ and also supplied to the controller RG as a measured value. The powers P ₃ , P ₄ are detected by power measuring devices MP ₃ , MP ₄ and supplied as a measured value to the controller RG.

Likewise, the operating voltage U _b is detected by a measuring device MU _b and fed as a measured value to the controller RG. Not all of these readings are required for a successful realization. Here only the potential is to be represented. A temperature measuring device measures the temperature T and provides it to the regulator RG. The regulator RG controls the current sources IS ₃ , IS ₄ with the aid of these measured values and, if appropriate, with the aid of externally obtained control specifications, in this case a desired value I _soll , as well as possibly stored and / or derived variables.

Fig. 2 : Here is contrary to Fig. 1 another resistor R ₃ drawn.

Fig. 3 points contrary to Fig. 1 a further output 8, which is also connected to the first terminal 5 via an external resistor R ₈ . The associated measuring devices MU ₈ , MI ₈ , MP _{8 also} supply the respective measured values P ₈ , U ₈ , I ₈ to the controller RG which controls the current sources as a whole. Typically, resistor R ₈ is chosen to be twice the value of resistor R ₄ .

Fig. 4 shows an exemplary control circuit for a RGB LED lighting. The control circuits 10_1, 10_2, 10_3 according to the invention each control an LED chain 11_1, 11_2, 11_3 of a color. The second terminals 4_1, 4_2, 4_3 are each connected via an external resistor R _{4_1} , R _{4_2} , R _{4_3} to the first terminal 5_1, 5_2, 5_3 of the respective LED chain 11_1, 11_2, 11_3. The respective first terminals 3_1, 3_2, 3_3 are connected directly to these. The second terminals 6_1, 6_2, 6_3 of the LED chains 11_1, 11_2, 11_3 are connected to the ground terminal 2 of the device 10. A reference generator RefG makes it possible to set the setpoint values (eg I _soll ) of the individual subdevices 10_1, 10_2, 10_3 externally by means of the currents I _{ref_ext_1} , I _{ref_ext_2} , I _{ref_ext_3} . These currents can be set via the resistors R _{ref_1} , R _{ref_2} , R _{ref_3} at voltage specification instead of current specification. A controller CTR controls the entire device. This can be addressed via a data interface ST. The exemplary device has a power supply SUP which processes the unregulated operating voltage U _b for use in the control circuit 10. A color controller FR receives from a color sensor MF information about the color composition and the intensity of the radiated light. This information is converted by the color exciter FR into setpoint specifications for the subdevices 10_1, 10_2, 10_3. As a result, a color composition and illumination intensity is set that meets a specification. Of course it is also possible to measure the reflected light and the lighting in To adjust dependence on it. In this case, for example, the setpoint specifications of different setpoint sources, which have been described above, can be combined with each other, for example, by multiplication in a suitable device, typically the controller RG, to a common setpoint input I _sum for the respective sum current I ₃ + I ₄ , I ₃ + I ₄ , + I ₈ and / or the distribution parameter Vp. An error detection compares the measured values of the measuring instruments of the sub-apparatuses 10_1, 10_2, 10_3 with target prescriptions and / or desired-specification ranges. You can also use past and derived values. If the error detector FD detects an error condition, this is output via an error signal S _stat . Of course, an output via the data interface ST is also possible. An internal reference intRef is used to set basic internal parameters.

Fig. 5 shows the distribution of power consumption in different operating voltage ranges for a device similar to the Fig. 1 , In a start-up transition A, the LEDs are not yet fully conductive and limit the total current I ₃ + I ₄ . In this area, typically only the first output 3 supplies the current for the operation of the load 11, the LEDs. In a second operating voltage range B, the current is gradually taken over by the second current branch at the second terminal 4 with the second external resistor R ₄ . The power P _R4 , which is thereby converted in the resistor R ₄ , increases parabolically. The power P _LED , which is converted in the LEDs, remains largely constant. From a certain operating voltage point, the second output 4 can no longer supply sufficient voltage. Therefore, the total current I ₃ + I ₄ would rise again through the LEDs and thus P _LED . Therefore, the additional power loss is now implemented in the control circuit in a third operating voltage range C. The loss line P _{10 of} the control circuit now increases continuously. The power consumption of the LEDs P _LED remains constant. The power consumption P _R4 , the second external resistance R ₄ remains constant. In a fourth operating voltage range D, the control can no longer be maintained and the system goes into emergency mode.

Fig. 6 shows the control characteristic of a preferred embodiment of the invention for the power supply of LEDs. This control characteristic is designed so that it has a plurality of operating voltage ranges as a function of the operating voltage U _b . For the following explanations, it is assumed for simplification that the first resistor R _{3 has} the value zero ohms. If there are several branches, then a resistor should have the value zero. In a first operating voltage range A, the light emitting diodes (LEDs) do not yet switch on. Therefore, in this operating voltage range, the current through the LEDs and thus the output power increases as a function of the operating voltage U _b . In this operating voltage range, the setpoint current I _sum is not yet output to the LEDs by the control circuit, since the total current I ₃ + I _{4 is} not limited by the control circuit 10 but by the LEDs, ie the load 11. During the transition from the operating voltage range A into a second operating voltage range B, the first output 3 supplies the entire current. The first output 3 is connected directly to the load 11 in this example. The output current I _{4 of} the second output 4, which is connected to the load 11 via the second external resistor R ₄ , is still 0 A at this operating voltage point. Therefore, the first output 3 must supply the total sum current I ₃ + I ₄ , because a voltage drop across the second external resistor R ₄ at the second output 4 is not desired. With the transition to the operating voltage range B, the regulator of the current source at the first output 3, in order not to supply more power, would have to lower its parallel to the current source connected internal conductance. This would lead to an increasing power loss in this controller. Therefore, the second output will gradually take over part of the total current I ₃ + I ₄ . This happens, for example, in such a way that the first output voltage U ₃ at the first output 3 of the control circuit 10 and thus the voltage which drops across the LEDs and thus the load 11, is kept constant. This means that the current I ₃ + I ₄ remains constant through the LEDs. This is the second output current I _{4 set} from the second output 4 so that via the second external resistor R ₄ , which is connected between the second output 4 and the LEDs, that is, the second terminal of the consumer 6, the additional voltage drops. Therefore, in this operating voltage range B, the power dissipation P _{R4 of} the second external resistor R _{4 increases} parabolically while the power dissipation P _LED released in the LEDs remains the same. At a certain point, the current source of the second output 4 no longer supplies enough current I ₄ to allow the voltage across the resistor to continue to rise with the operating voltage U _b rising further. This point marks the transition to another operating voltage range C in which both the power P _R4 in the second external resistor R ₄ and the power P _LED in the LEDs remain nearly constant. The additional power loss must now be eliminated in the control circuit 10 itself, which can only be done up to another operating voltage point. Then, a transition into an operating voltage range D, in which the power must be lowered in total, in order to prevent destruction of the control circuit 10 and / or the LEDs, ie the load 11. In this operating voltage range D is typically a correct or complete function of the consumer 11 or all consumers are no longer possible or possible.

If more than two outputs are used to supply a load, in this case an LED chain, then naturally more complex area patterns are conceivable.

In the areas B and C, therefore, the sum of the output currents I ₃ + I _{4 is} kept constant. In the area B is readjusted with the output current I _{4 of} the second output 4, while in the region C by the voltage drop across the control circuit 10, the sum current I ₃ + I ₄ is readjusted by the load 11 and kept constant. The area D is an area which is typically outside the respective specification for the control circuit 10 and therefore only has emergency running characteristics.

Fig. 7 shows a circuit arrangement similar to that according to Fig. 1 but with a reduced number of input and output connections. Incidentally, the operation of this circuit is the same as that described above.

Based on the embodiments according to Fig. 8 It can be seen that the consumer 11 is supplied via a total of four power modules. In each case two of these power modules are connected to one terminal of the consumer, each of these power module pairs having a possible low impedance (ideally without effective ohmic resistance) connected to the consumer path and a power path with external resistance.

To clarify and generalize the concept of the invention, it should be stressed at this point that the term "external resistance" does not necessarily mean an ohmic resistance. Rather, this term is intended to express, as it results from the context of the invention, that a power dissipation consumer arranged outside the IC is present, which delivers electrical power loss in the form of, for example, heat to the environment.
