Definitions
- the invention relates to a device for controlling a consumer according to the preamble of claim 1.
- Such a device is known for example from DE-OS 38 05 031.
- a device for controlling a consumer in particular an electromagnetic consumer, is described.
- the current flowing through the consumer is measured and adjusted to a setpoint.
- av "in series is then driven to the consumer lying switch from the current flowing through the load current.
- Power transistors are preferably used as switches. If the current is set by means of an analog control, there is a very high power loss in the power transistor.
- the power consumption of transistors essentially depends on the maximum permissible temperature and the heat connection to the environment. Exceeds that Power loss the maximum power consumption of the transistor, a transistor with a higher maximum power loss is usually used and / or the power loss is divided over several transistors. These measures are often too expensive or are not sufficient.
- the invention has for its object to show a device for controlling a consumer of the type mentioned, how the power dissipation of the power transistor can be reduced.
- Figure 1 shows schematically the most important elements of the device according to the invention.
- Figure 2 shows various signals occurring in the device. Description of the exemplary embodiment
- the consumer is the coil of a solenoid valve, which influences the fuel metering in an internal combustion engine.
- a solenoid valve By triggering this solenoid valve, the start of injection, the end of injection and thus the amount of fuel injected can be controlled.
- the solenoid valve opens and / or closes at a defined point in time.
- the solenoid valve reaches its new end position as quickly as possible after the control signal is output.
- the electromagnetic consumer is designated with 100. This is connected to its one terminal with battery voltage. With its other connection it is connected to a control means 110.
- the control means 110 is preferably a transistor, in particular a field effect transistor.
- the second connection of the consumer is connected to the drain connection of the field effect transistor 110.
- the source connection of the transistor 110 is connected to a current measuring means 120 for detecting the current flowing through the consumer.
- the second terminal of the current measuring means 120 is connected to ground.
- connection point between the second connection of the consumer 100 and the control means 110 is connected to the first connection of a resistor 150.
- the second connection of the resistor 150 is connected to a switching means 140.
- a transistor, in particular a field effect transistor, is preferably used as switching means 140.
- the second terminal of resistor 150 is connected to the drain terminal of transistor 150.
- the source of transistor 140 is in contact with the connection point between control means 110 and current measuring means 120.
- the gate connection of transistor 140 and the gate connection of transistor 110 are acted upon by a control unit 130 with Ar control signals.
- the current measuring means 120 is preferably implemented as a resistor.
- the two connections of the resistor 120 are scanned by the control unit 130.
- the two voltage values are fed to a current detector 132, which provide an actual current value I s based on the voltage drop across resistor 120.
- This actual value Ii s t 133 is supplied to a controller as an actual value.
- the second connection of the controller 133 is connected to a setpoint input 131, which applies a setpoint I so n to the second input.
- the output of the controller 133 applies a corresponding signal to the gate of the transistor 110.
- control device 130 evaluates various output signals from sensors 135. The mode of operation of this device is described below with reference to FIG. 2.
- the control signal for the control means 110 in the second line the control signal for the switching means 140 and in the third line the current through the switching means 140 as a broken line and the total current flowing through the solenoid valve 100 as solid line.
- control means 140 and control means 110 are fully switched through.
- the current flowing through the solenoid valve increases to the desired value for the attracting current I so ll ⁇ to - the time T2 of the pull-in current is achieved.
- the resistance of the control means 110 is equal to or less than the resistance of the switching means 140 and the resistor 150. In this phase, most of the current flows through the control means 110 and only flows in small part by the switching means 140.
- the activation of the control means 110 is withdrawn from the time T2. This means that the resistance of the control means 110 increases. As a result, the current flowing through the switching means 140 increases.
- the setpoint for the current is lowered to its holding current level I so ll 2 . This means that the control for the control means 110 is further reduced. The resistance of the control means 110 and thus the current through the switching means 140 thereby increase.
- the activation of the solenoid valve ends at time T4.
- the resistor 150 is dimensioned such that the largest current component flows through the switching means 140 and the resistor 150 from the time T3. Only a small amount of current flows through the control means 110. This is achieved in that the branch consisting of the resistance means 150 and the switching means 140 has a smaller resistance than the control means 110 in the period between T3 and T4.
- the branch consisting of the resistance means 150 and the switching means 140 also absorbs most of the power loss.
- the control means is regulated back so far that the current flowing through the control means 110 now corresponds to the difference between the setpoint I so ll u 111 ⁇ the current flowing through the switching means 140.
- the switching means 140 is fully switched through and operates as a switch. Most of the current flows through the switching means 140.
- the branch consisting of resistor 150 and switching means 140 also absorbs most of the power loss.
- the control means 110 works as an analog current regulator. The control means 110 receives the differential current between the setpoint and the current flowing through the switching means 140.
- resistor 150 The major part of the energy loss is implemented in resistor 150 and not in a transistor. Resistors can be essential compared to transistors at the same cost higher temperatures can be designed. A good heat connection to the environment or to heat sinks can be achieved with little effort. The control of the output stages is simple in comparison to the circuitry required for the distribution of the power loss over several power transistors.
- the power resistor 150 need not have a narrow tolerance, since the control means 110 carries out a current regulation. Furthermore, the resistor 150 can be attached externally by the control device, for example in the vicinity of the consumer 100.
