- the switching means as transistors are exemplary embodiments educated.
- the control connections of the switching means are applied by the control 100 with control signals.
- the second connections of the consumers are in each case via at least one diode with the first connection of a other consumer in connection.
- the second stands Connection of the consumer EV1 via a diode D12 with the first connection of the consumer EV2 in connection.
- the second connection of the second stands accordingly Consumer EV2 via the diodes D23 and D24 with the first Connection of the third or fourth consumer in Contact.
- the second connection of the third consumer EV3 is connected via diodes D31 and D34 to the first connection of the first consumer EV1 and the fourth consumer EV4 in Contact.

It can also be provided that the second connection of each consumer via diodes with the first connections of all other consumers in Connection is established.
- FIG 2 there are various signals over time t applied.
- part figure 2a) is the control signal for the Transistor T1
- in the second sub-figure 2b) is the through the first consumer EV1 flowing current I1
- in partial figure 3c) is the control signal for the switch T2 and in Part 2d) the flowing through the second consumer Current I2 plotted.
- FIG. 1 The mode of operation of FIG. 1 is described below illustrated embodiment with reference to FIG. 2 clarifies. For simplification, it is provided that the Consumers only via one diode with another Communicate with consumers.
- consumer EV2 takes over Energy storage for the fourth consumer EV4.
- To the Time t6 then becomes the next consumer in particular EV4 switched on. It is particularly advantageous that a suitable cascading of the output stages one or several consumers are storing energy for others takes over.
- FIG. 1 In this embodiment shown in Figure 1 is used one or more consumers each as energy storage for another consumer.
- Figure 3 is an embodiment shown in which an additional inductance is provided, which serves as an energy store.
- the single ones Consumers EV1 to EV4 each have a switching device T1 to T4 connected to ground.
- the first connections of the Consumer EV1 to EV4 stand with the cathode of a diode D11 and a second terminal of a capacitor C11 in Connection.
- the anode of the diode D11 and the first connection of the capacitor C11 are at a supply voltage Ubat in contact.
- the Ubat supply voltage is via an inductor I10 and a switching means T10 connected to ground.
- the Switching means T10 is also controlled by the controller 100 controlled.
- the connection point between the switching means T10 and the inductance I10 are connected via a diode D10 the common connection of all consumers EV1 to EV4 and the diode D11 and the capacitor C11 in contact.
- the inductance I10 is designed to be very quickly, for example within a millisecond, can store enough energy to make a quick To enable switching of a consumer.
- diode D10, D11 and the capacitor C11 together with the inductance I10 and the switching means T10 combined to form a memory module be marked with a dashed line is.
- the switching means T10 Before one of the consumers is to be controlled the switching means T10 closed, so that in the inductance I10 the current increases and is stored in energy. To the Time at which the consumer is switched on the switching means T10 is in its locked state transferred and the energy from the inductor I10 commutates to the capacitor C11 and increases the Supply voltage briefly so that the consumer opens faster. Since only one consumer is controlled a memory module can be used by all consumers supply.
- the consumer I10 for can be energized for a longer period of time and thereby absorbs more energy than a consumer at Embodiment according to FIG. 1.
- FIG. 1 Another embodiment of a circuit is shown in FIG shown for fast and precise control of power amplifiers.
- the coils of the injection valves are again with EV1, EV2 and Designated EV3.
- EV1, EV2 and Designated EV3 In the illustrated embodiments only three consumers are shown. The The procedure according to the invention is, however, for everyone any number of consumers can be used.
- the second Connections of the consumers are each via a Switching means T1, T2 and T3 connected to ground.
- the Switching means T1, T2 and T3 are the same as in Figure 3 acted upon by control 100 with control signals.
- connection point between the consumer EV1 and the first switching means T1 is connected to a via a diode D2C first connection of a capacitor C1 in connection, the second connection is connected to earth.
- the first The capacitor C1 is connected via a switching means TB in contact with the first connection of the consumer EV1.
- a voltage divider consisting of resistors R10 and R11 exists, switched.
- the connection point of the two Resistors are in contact with controller 100, which too controls the switching means TB.
- the switching means are shown in the Embodiment shown as transistors. Instead of the transistors can also use other switching elements in particular field effect transistors or thyristors be used.
- a Intermediate store provided in the form of a capacitor, in where the energy released when switching off is stored and at the start of control via a switching device Consumer is fed.
- This facility works as follows. As long as the Consumer EV1 to EV3 can not be controlled clocked at high frequency on and off. The shutdown energy comes from consumers EV1 to EV3 thereby via the diodes D1C, D2C and D3C into the capacitor C1. The voltage at the first terminal of capacitor C1 will by means of the voltage divider consisting of the resistors R10 and R1 detected and from the controller to one specified value.
- the consumer EV1 should now be controlled are, the switching means T1 and the Switching means TB transferred to the closed state. This has the consequence that a voltage of 80 volts is present. This leads to a very quick one Current rise and thus to a quick switching process of the Consumer.
- the starting current and / or the holding current can be controlled of the switching means T1 can be regulated to predetermined values.
- Charging the capacitor C1 is problematic.
- the current, with which consumers are charged must be sufficient be high so that a fast charging process can be achieved can.
- the current may have a certain value do not exceed, otherwise the consumer will Switching state changes.
- FIG. 5 a circuit arrangement according to FIG. 5 is special advantageous. Such an arrangement is usually called Designated H-bridge circuit.
- the exemplary embodiment is only a consumer EV1 shown.
- the consumer is on with his first connection Switching means T15 with a first connection of a Capacitor C1 connected.
- the first connection is also available of the consumer EV1 via a switching device T45 with mass in Connection.
- the second connection of the consumer EV1 is via a switching device T25 with ground and via a Switching means T35 with a supply voltage Ubat in Connection.
- the supply voltage Ubat is also via a diode D1B in contact with capacitor C1.
- the cathodes of the diodes D1B and D1C are each connected to the first port of the Capacitor C1 connected.
- the second connection of the Capacitor C1 is in contact with ground.
- the switching means T35 and T45 corresponds to its function Switching means T1 in the embodiment according to FIG. 4.
- a particularly advantageous embodiment results if the diode D1B corresponding to that in Figure 4 between the Supply voltage and the first connection of the consumer is arranged.
- a shared memory can be used for all consumers
- an injection occurs when the controlling solenoid valve closed is.
- the overclocking takes place such that the valve is in its open position remains or moves to its open position. This means the overclocking takes place so that the current flow Converts consumers to a safe state.
- the flow of electricity through the consumer is at times when he is controlled so that he is in a safe Condition, released and interrupted several times, the one that is released when the current flow is interrupted Energy is stored in a capacitor.
- the flow of electricity will release such that the consumer in his safe condition Remains. This means control is so short that it is not sufficient for switching, or the Electricity flows in a direction that the consumer in his holds a secure position.
