Definitions
- the invention is based on a matching circuit with two input and two output terminals for controlling an electronic component or an assembly according to the preamble of the main claim.
- the problem often arises that when an electronic component which can be used in different circuits is controlled, voltage signals with very different amplitudes have to be adapted to the input conditions of the component. It may be that in one case an AC voltage of 220 V and in the other case a DC voltage of 5 V must be processed.
- matching circuits for example with a series resistor, were designed in such a way that a suitable voltage is available at the output of this matching circuit for the downstream component or the assembly, which does not destroy the component or the assembly . In practice, this inevitably led to very different adapter circuits, which, particularly in the case of series production of different device types, require a great deal of effort and a large amount of storage.
- Voltage ranges can be used. It is particularly advantageous that both direct voltages and alternating voltages can be processed, so that only a single matching circuit has to be manufactured for all types of application. This simplifies the development effort and reduces manufacturing and storage costs.
- Adaptation circuit possible. It is particularly advantageous that the means provided are dimensioned such that they can be used for all types of voltage occurring.
- Diode circuit preferably to be used in a bridge circuit, since AC voltage signals can thus also be implemented at a DC voltage level.
- a current limiter which has an active semiconductor circuit.
- the loss conduction via the current limiter increases only proportionally to the voltage with increasing voltage amplitude.
- the power loss would increase with the square of the current with increasing voltage and thus disadvantageously generate a lot of heat.
- an optocoupler is advantageously connected to the output terminals of the matching circuit.
- a particularly advantageous application of this matching circuit results in control circuits, in particular in the control of signal systems or traffic light systems.
- FIG. 1 shows a circuit diagram of the adapter circuit
- FIG. 2 shows an optocoupler
- FIG. 3 shows a circuit diagram of an active current limitation.
- the circuit diagram according to FIG. 1 shows the basic arrangement of the adapter circuit according to the invention.
- a diode circuit 1 designed as a bridge circuit is connected with its input terminals 5 and 6 to a control voltage U ⁇ .
- the outputs of the diode circuit 1 are connected to an output terminal 7 and an output terminal 8 via a node 9 and an active current limiter 2.
- An input of an electronic component or an electronic assembly 3 is subsequently connected to the two output terminals 7, 8.
- the output terminal 8 is preferably designed as a ground line.
- Diode circuit 1 is designed in such a way that it can take up, for example, both a 220 V alternating voltage or a 5 V direct voltage as the control voltage U ] .
- the voltage is rectified and transmitted to the output terminals 7, 8 via the active current limiter 2, see above that it feeds a load resistor 3 as voltage U2.
- the load resistance is the input resistance of the downstream component or assembly.
- a simple rectifier circuit or, in the simplest case, no rectifier is provided if the use of the matching circuit is basically only intended for DC voltages.
- an optocoupler 20 is connected to the output terminals 7, 8.
- the optocoupler 20 is connected to the input terminals 24, 25 according to FIG
- Output terminals 7, 8 switched so that the light-emitting diode 22 is traversed by the current i of the active current limiter 2.
- the light-emitting diode 22 sends light signals to the photo transistor 21, which connects the terminals 26, 27 through its collector-emitter path. It is clear that the terminals 26, 27 must be supplied accordingly.
- FIG. 3 shows an exemplary embodiment of an active current limiter 2, which is connected between the connections 9 and 7 according to FIG. 1.
- the second transistor 31 has two negative feedback transistors 30, 31, the second transistor 31 being connected in parallel with its base-collector path to the emitter-base path of the first transistor 30.
- a first resistor 32 is connected between the terminal 9 and the base of the first transistor 30.
- Parallel to the base-emitter path of the second transistor 31 is an in the emitter current path of the first transistor 30 second resistor 33 switched.
- the emitter output of the second transistor 31 is connected to the output terminal 7.
- MOSFET transistors instead of the bipolar transistors.
- the dielectric strength of the two transistors 30, 31 must be taken into account with regard to the possible control voltage.
- Output terminal 7 thus results in a relatively small current with a limited voltage. If, on the other hand, the voltage at terminal 9 rises, the voltage drop across the second resistor 33 increases with increasing current i, so that the second transistor 31 increasingly switches to the conductive state. At a certain current i, the second transistor 31 becomes conductive and blocks the first transistor 30. As a result, the current i is limited to a maximum value that can be set by the second resistor 33.
- the second resistor 33 can be dimensioned so that the
- Matching circuit 2 can be used for a wide range of control voltage U ⁇ .
