Definitions
- the invention relates to a circuit arrangement as specified in the preamble of claim 1.
- Such a circuit arrangement is already known from DE-OS 2 043 423.
- the known circuit arrangement is a two-point controller, which is fed from a solar generator.
- the two-point controller is designed and dimensioned so that the current emitted by the solar generator is in a predetermined ratio to the short-circuit current of a reference solar generator.
- This ratio is determined using the characteristic field of the solar generator as the factor by which the short-circuit current is to be multiplied in order to obtain the current at the operating point of maximum power.
- a test cell belonging to the solar cell generator serves as the reference solar generator.
- the solar generator feeding the consumer and the solar generator whose short-circuit current is measured are therefore of the same design. In this way, the operating point of maximum power is achieved with good approximation in a large temperature range of the solar generator and this with relatively simple means.
- the circuit arrangement is used in particular to charge a battery or to feed consumers that are buffered with the aid of a battery.
- the proposed type of current adjustment can also be advantageous for other consumers if the greatest possible utilization of the solar generator is aimed for.
- the circuit arrangement can be part of a regulator or an arrangement for so-called forward regulation, in which the actuator is controlled in a predetermined dependence on the measured short-circuit current. Since the test cell is permanently loaded by a measuring resistor, it is not available for supplying the consumer. In addition, the measured value of the short-circuit current of the test cell, which serves as a criterion for the short-circuit current of the solar generator, is only an approximate value, since the properties of the test cell are used to infer that of the entire solar generator.
- a switching regulator is connected to a solar generator, with the aid of which the output voltage of the circuit arrangement is kept at a predetermined value. This is achieved in that the actual value input of the switching regulator is connected to the tap of a first voltage divider which is parallel to the output of the circuit arrangement.
- the switching regulator has another control input that is routed internally to a reference voltage source. This control input is due to a tap of a second voltage divider, which is connected to the solar generator.
- a photodiode is attached directly next to the solar generator and is arranged in parallel with a resistor of the second voltage divider.
- the solar generator is to be given a maximum of power in that the reference voltage effective in connection with a voltage regulation is correspondingly influenced by the photodiode when the light irradiation changes.
- the temperature in addition to the radiation density, the temperature also has a significant influence on the generator voltage at the operating point of maximum power.
- the latter is not taken into account in the known circuit arrangement.
- a typical characteristic field of a solar generator is e.g. from the brochure Solar Modules, Type Series SM36 from Interatom.
- a particularly simple type of adaptation would be to determine the current drawn for a frequent average radiation intensity.
- this would have the disadvantage that the possible higher current could not be used in the case of stronger radiation and the voltage would collapse in the case of weaker radiation and charging would no longer be possible.
- the object of the invention is to design a circuit arrangement of the type mentioned at the outset in such a way that it ensures, with comparatively little effort, that the solar generator operates at a working point which in a large working area largely comes close to the working point of maximum power.
- the object is achieved by the measures specified in the characterizing part of claim 1.
- the short-circuit current of the solar generator feeding the load is evaluated periodically.
- the short circuit current of the solar generator is measured particularly precisely and with particularly low power consumption.
- the circuit arrangement therefore works with a particularly good efficiency.
- circuit arrangement is expediently designed in the manner specified in the characterizing part of patent claim 2.
- the pulse-pause ratio of the pulse train that closes the first controllable switch can in particular be 1: 1000, so that the efficiency is practically not impaired.
- the battery 9 is fed from the solar generator 1 via a control device.
- the main circuit H runs from the positive pole of the solar generator 1 via the diode 31 which is polarized in the forward direction, the inductor 4 and the diode 5 which is polarized in the forward direction to the positive pole of the battery 9 and from the negative pole of the battery 9 via the measuring resistor 7 to the negative pole of the solar generator 1.
- a series connection of the electronic switch 24 controlled by the clock generator 21 and the short-circuit current measured value 2 is located in a first transverse branch.
- the resistor 22 can be arranged in a longitudinal branch between the solar generator 1 and the first transverse branch instead of in the first transverse branch. Lower losses result from an arrangement in the first transverse branch.
- the capacitor 32 lies between the connection point of the diode 31 with the inductor 4 on the one hand and the connection point of the resistor 7 and the load 9 on the other hand.
- the electronic switch 6 which is controlled by the control circuit 8, is located in a third transverse branch.
- the control circuit 8 is supplied with voltage from the solar generator 1 in a manner not shown.
- the negative pole of the battery 9 also serves as a ground connection or reference potential.
- the setpoint input 82 of the control circuit 8 is connected to the output of the sample and hold circuit 23 of the setpoint generator 2a.
- the actual value input 81 of the control circuit 8 is connected to the terminal of the current measuring resistor 7 facing away from the battery 9.
- the storage choke 4, the electronic switch 6 and the rectifier 5 represent the power components of a step-up converter known per se.
- the switch expediently consists of a semiconductor component.
- the converter charges the battery 9 from the solar generator 1.
- the control device or control circuit 8 compares the current of the solar generator measured at the measuring resistor 7 with the value of the short-circuit current measuring resistor 22 measured at the short-circuit current measuring resistor 22 and regulates the current to a predetermined fraction of the respective measured value of the short-circuit current.
- the regulated current results from the pulse-pause ratio of the pulses that close the second switch.
- the pulse-pause ratio can be achieved by pulse duration modulation for a fixed switching frequency or by varying the frequency for a fixed pulse duration.
- the capacitor 32 serves to provide the step-up converter with the necessary current pulses and also with a sufficient input voltage during the short periods in which the short-circuit current is measured.
- the diode 31 ensures that the capacitor 32 is not discharged when the electronic switch 24 is closed.
- control circuit 8 switches to voltage regulation and prevents a further rise in voltage or switches back to the lower value for trickle charging, as a result of which the current consumed can decrease.
- the productivity of the solar generator is then no longer fully utilized.
- the measuring resistor 7 measures the direct current output by the solar generator 1. If one arranges the measuring resistor in deviation from FIG. 1 between the capacitor 32 and the switch 6, a voltage corresponding to the direct current can be obtained by averaging or eliminating the alternating current component caused by the switch 6.
- a series circuit comprising the source-drain path of the field-effect transistor 24a and the short-circuit current measuring resistor 22 is connected in parallel to the 36-volt solar generator 1.
- the field-effect transistor 24a forms the electronic switch 24 1 and is periodically closed by clock pulses from the clock generator 21.
- the clock 21 consists of the clock module 21 a and the external circuit shown.
- the field effect transistor 24a is driven by the clock generator 21 via an inverter stage.
- the clock generator 21 emits pulses at intervals of 100 msec, the duration of each of which is 100 ⁇ sec.
- the pulse duty factor of the measuring pulses with which the short-circuit current of the solar generator 1 is measured is therefore 1: 1000.
- the time module 21 b derives sampling pulses from the 100 usec pulses of the clock module 21a, the duration of which is only about 85 to 90 usec, so that the last 10 to 15% of the pulse width of the measuring pulse is not evaluated.
- the sampling and holding circuit 23 is connected with its sampling pulse input c3 to the output b3 of the time module 21b. Since the scanning pulse always ends before the short-circuit current measuring pulse, decay processes of the measuring pulse cannot falsify the value to be stored in the scanning and holding circuit.
- the source electrode of the field effect transistor 24 connected to the measuring resistor 22 is connected to the measuring pulse input c7 of the sample and hold circuit 23.
- the sample and hold circuit 23 outputs a reference voltage proportional to the short-circuit current of the solar generator 1 at its output 82.
- FIG. 2 An embodiment of the device for measuring the solar generator short-circuit current with design information is shown in FIG. 2.
- connection number for the integrated circuit concerned.
- connection number is preceded by an “a” for the clock module 21 a and a “b” in the time module 21 b.
- the positive auxiliary voltage + U H and the negative auxiliary voltage -U H are, for example, ⁇ 12 V.
- the auxiliary voltages are generated using a conventional device, which is not shown in the figures.
- This device can contain a charging capacitor connected to the solar generator via a decoupling diode.
- a stabilization circuit with a transistor in the series branch and a Zener diode as a setpoint generator in the cross branch can be connected to the charging capacitor.
- a constant current diode is expediently located parallel to the base collector path of the transistor.
- the voltage stabilized in this way is expediently fed to a converter module which outputs the positive auxiliary voltage + U H and the negative auxiliary voltage -U H.
- An integrated circuit of type SI 7661 can be used as a converter module.
- FIG. 3 shows a control circuit for controlling a field effect transistor 6a, which forms the switch 6 of the circuit arrangement according to FIG. 1.
- the operational amplifier 84 is connected with its plus input to the output 82 of the sample and hold circuit 23 according to FIG. 1 or FIG. 2.
- the measuring resistor 7 is on one side at the reference potential of the operational amplifier 84.
- the other side of the measuring resistor 7 is connected to the minus input of the operational amplifier 84 via a further resistor.
- There is a voltage across the measuring resistor 7 which is proportional to the instantaneous value of the current which is taken from the solar generator.
- the residual ripple of the measuring voltage is reduced with the help of the RC element 7a.
- the output of the operational amplifier 84 is connected to the connection d5 of the pulse width modulator 87.
- the pulse width modulator 87 outputs permanently modulated control pulses for controlling the field effect transistor 6a at its output d7 as a function of the control deviation. This is achieved in that the variable supplied to the input d5 and proportional to the control deviation is compared with a sawtooth voltage supplied to the input d6.
- the sawtooth voltage is generated using the oscillator 85, the frequency of which is, for example, 50 kHz.
- the inverter 86 Between the output of the oscillator 85 and the input d5 of the pulse width modulator 87 there is the inverter 86, which distributes the edges of the output pulses of the oscillator 85. Between the output of the pulse width modulator 87 and the gate electrode of the field effect transistor 6a there is a chain circuit comprising the inverter 88, which also serves to increase the pulse edges, and the inverter 89, which serves as a driver.
- a voltage proportional to the control deviation is obtained from the reference voltage coming from the sample and hold circuit 23 and from the actual value measured at the measuring resistor 7.
- the value of the measuring resistor is e.g. 8 m S
- the short-circuit current measuring resistor 22 has e.g. a value of 6.8 m n.
- the resistance ratio of the resistors 7 and 22 is 0.85 in this case. This is the predetermined ratio of the current drawn from the solar generator to the measured short-circuit current of the solar generator.
- the storage capacitor 32 has e.g. a capacity of 8000 uF and forms a low-resistance voltage source for the charge controller connected to it.
- the rectifier 31 prevents the storage capacitor 32 from being able to discharge via the short-circuit current measuring resistor 22.
- FIG. 3 An embodiment of the control circuit with design information is shown in FIG. 3.
- An integrated module LM 393 serves both as oscillator 85 and as pulse width modulator 87.
- An integrated component 4049 B is used as the inverter 86 and 88 and as the driver 89, the driver being formed by four inverters connected in parallel.
- the designations of the connections of the oscillator 85 and the pulse width modulator 87 contain the connection numbers customary in the integrated modules LM 393. These connection numbers are preceded by a "d".
- the characteristic curve field of a solar generator shown in FIG. 4 shows characteristic curves for different radiation densities E as parameters.
- the voltage depends to a large extent on the temperature and the operating point of maximum power is therefore significantly influenced by the temperature of the solar generator.
- the influence of temperature on the current is comparatively small.
- an operating point is selected at which the load current in a predetermined ratio to. measured short-circuit current.
- the predefined ratio can be determined for the solar generator used in each case by dividing the current at the operating point of maximum power by the associated short-circuit current for the relevant characteristic curves and forming an average value from the quotients obtained in this way.
- Fig. 1 shows a preferred embodiment of the invention, which contains a step-up converter as a current regulator.
- the generator voltage is increased to the required charging or consumer voltage.
- step-up converters with exclusive regulation of the output voltage there is the advantage that the controller does not attempt to draw such a large current from the solar generator that the generator voltage breaks down.
- step-up converter instead of the step-up converter shown, other known control arrangements, in particular blocking and flow-through converters, can also be used in a corresponding manner. These are usually implemented with pulse width control and have a transformer.
- the current emitted by the solar generator is regulated.
- a commercially available controller module designed as an integrated circuit can serve as the control circuit 8.
- An advantageous modification of the circuit arrangement according to FIG. 1 consists in particular in that the load current measuring resistor 7 is replaced by a short circuit and the input 81 of the control circuit 8 is omitted.
- the control circuit 8 is designed as a so-called forward regulator, which specifies one for each measured value of the solar generator short-circuit current bene control variable for controlling the actuator 6 forms.
- the control circuit 8 expediently contains a comparator which compares a sawtooth voltage with the measuring voltage proportional to the short-circuit current or a voltage derived therefrom and switches the electronic switch 6, which was switched on at the beginning of the sawtooth, in the event of equality of voltages.
