Definitions
- the invention relates to an electronic circuit arrangement for controlling excitation windings of electromagnetic components provided with additional circuitry, in particular free-wheeling circuitry, preferably solenoid valves, according to the preamble of the main claim.
- Such circuit arrangements are used, for example, to control the field windings of solenoid valves, as are used in particular in the control of injection systems for internal combustion engines.
- the electronic circuit arrangements known in the case of injection systems for internal combustion engines require a relatively large circuit outlay for the control of the solenoid valves, so that on the one hand a relatively high production price arises, but on the other hand a corresponding space requirement for the electronic components must also be made available.
- the electronic circuit arrangement according to the invention with the features mentioned in the main claim has the advantage that the additional circuitry is used several times for the individual electromagnetic components, but nevertheless the individual electromagnetic components can be switched on and off independently of one another. This reduces the outlay on equipment and thus also the space required, but nevertheless creates flexible control.
- the circuit structure according to the invention is also particularly simple in that only three different collection points are formed, to which the additional circuitry common to all electromagnetic components is then connected.
- a freewheeling switching element belonging to the additional circuitry lies between the component-side collecting point and the diode-side collecting point.
- the latter is preferably designed as a free-wheeling transistor. So this- ses freewheeling switching element each the freewheeling flow of all electromagnetic components when they are switched off.
- the invention also considerably reduces the circuit complexity on the operating voltage source side, in that a protective diode belonging to the additional circuit is located in series with the operating voltage source between the component-side collection point and the circuit element-side collection point.
- This protective diode is accordingly assigned as the sole component to all electromagnetic components.
- a series resistor belonging to the additional circuit can also preferably be connected in series with the operating voltage source, which series resistor is consequently also subject to multiple use.
- the invention is explained below with reference to the drawing.
- the figure shows a schematic diagram of a circuit diagram of the electronic circuit arrangement.
- the electronic circuit arrangement has a multiplicity of solenoid valves MV 1 to MV n , which represent electromagnetic components provided with excitation windings.
- the large number of solenoid valves MV 1 to MV n is identified in the figure by the row of dots.
- the beginnings of the individual field windings of the solenoid valves MV 1 to MV n are connected to a collection point A via lines 1.
- the ends of the field windings of the solenoid valves MV 1 to MV n lead via lines 2 to controllable switching elements 3, which are designed as bipolar transistors T 1 to T n .
- each solenoid valve MV 1 to MV n is assigned a bipolar transistor T 1 to T n .
- the individual lines 2 lead via the respective collector-emitter path of the transistors T 1 to T n via lines 4 to a further collection point B.
- Each line 2 leads to a diode D 1 to D n and from there via lines 5 to a third collection point C.
- the procedure is such that between the component-side collecting point A and the diode-side collecting point C there is a free-wheel switching element 6, which is part of the additional circuit and is designed as a free-wheeling transistor T F.
- An extinguishing capacitor C L is also connected between the switching element-side collecting point B and the diode-side collecting point C.
- the specific circuit arrangement of the freewheeling transistor T F and the quenching capacitor C L is not shown in detail in the figure; it is only indicated by the representation of the circuit board 7 receiving these components.
- the circuit of the circuit board 7 receives its supply voltage via lines 8 shown in broken lines, which lead to an operating voltage source 9.
- the positive pole of the operating voltage source 9 leads to a protective diode 10, the other connection of which leads to the collecting point A.
- the negative pole of the operating voltage source 9 is connected to a series resistor 11, the further connection of which leads to the collecting point B.
- the procedure is such that the anodes of the diodes D 1 to D n are connected to the lines 2 and their cathodes to the collecting point C.
- the anode of the protective diode 10 stands with the plus pole of the operating voltage source 9 in connection, while the cathode leads to the collecting point A.
- the circuit arrangement works as follows:
- the circuit arrangement shown also makes it clear that by looping in the quenching capacitor C L between the collection points B and C, a corresponding quenching can be carried out when the individual solenoid valves MV 1 to MV n are switched off independently of one another.
- a corresponding quenching can be carried out when the individual solenoid valves MV 1 to MV n are switched off independently of one another.
- solenoid valves MV 1 to MV n only one extinguishing component is required.
- both the protective diode 10 and the series resistor 11 are used jointly for the large number of solenoid valves MV 1 to MV n , so that an optimal ratio with regard to the use of components is present, although individual circuit parts can still be controlled independently of other circuit parts.

Abstract
Des circuits électroniques servent à commander les enroulements excitateurs de composants électromagnétiques pourvus de connexions à des circuits complémentaires, notamment des circuits en régime libre; de préférence, ces composants sont des soupapes magnétiques (MV1 à MVn) et sont connectés en série à un élément réglable de commutation (3), ce qui permet d'obtenir un réglage flexible. Afin de réduire la quantité de circuits, le coût de fabrication et le volume, les bornes (1, 4) de cette connexion en série mènent directement à un point collecteur (A, B, C); de même, les connexions (2) entre les composants (MV1 à MVn) et les éléments de réglage (3) mènent également à ces points collecteurs (A, B, C), par l'intermédiaire de diodes (D1 à Dn). Un seul circuit complémentaire (TF, CL, 10, 11) commun à tous les composants est connecté à ces points collecteurs. Les éléments du circuit complémentaire sont ainsi utilisés de façons multiples, étant donné qu'ils sont à disposition de tous les composants électromagnétiques.Electronic circuits are used to control the excitation windings of electromagnetic components provided with connections to complementary circuits, in particular free-running circuits; these components are preferably magnetic valves (MV1 to MVn) and are connected in series to an adjustable switching element (3), which makes it possible to obtain flexible adjustment. In order to reduce the quantity of circuits, the manufacturing cost and the volume, the terminals (1, 4) of this series connection lead directly to a collecting point (A, B, C); similarly, the connections (2) between the components (MV1 to MVn) and the adjustment elements (3) also lead to these collecting points (A, B, C), by means of diodes (D1 to Dn). A single complementary circuit (TF, CL, 10, 11) common to all the components is connected to these collecting points. The elements of the complementary circuit are thus used in multiple ways, since they are available to all the electromagnetic components.
