Wenn der Gene-Schalter 22 an der Batterie angeschlossen. 15 rator34 Spannung liefert, wird der Schalter, der In Fig. 2 liegt wiederum eine Batterie 33 des durch den Transistor 51 gebildet ist, geschlossen und Kraftfahrzeuges an zwei Klemmen 31, 32. An den auf diese Weise die Widerstände 38, 39 direkt an Klemmen 31, 32 liegt außerdem ein Generator 34. die Klemmen 31, 32 gelegt. Zur gleichen Zeit erlischt Verbraucher 35, die von der Batterie speisbar sind, die Kontrollampe 37, da sie kurzgeschlossen ist.

Ein Punkt zwischen den 25 Wenn jedoch die vorbestimmte Spannung erreicht Widerständen 38, 39 ist über eine Zenerdiode 41 mit ist, zündet die Zenerdiode 41 und leitet einen Basisder Basis eines n-p-n-Transistors 42 verbunden, strom an den Transistor 42, der hierdurch in den dessen Emitter an der Klemme 32 und dessen leitenden Zustand versetzt wird und der jetzt den Kollektor über einen Widerstand 43 in Reihe mit Basisstrom, der durch den Transistor 44 fließt, von dem Zündschalter 36 an der Klemme 31 liegt.

Der zweite 40 stimmt, der durch die Zenerdiode 41 fließt, so daß Teil 18 des in Fig. 1 beschriebenen Spannungsreglers je größer die Ausgangsspannung des Generators 34 ist in Fig. 2 durch den Stromkreis des Transistors 44 wird, um so weniger Strom durch die Wicklung 45 gebildet. Der Kollektor des Transistors 44 ist ferner fließt.feeds and lights up; the field winding of the genus at the star point or via a smoothing rator is also excited. As soon as the generator 16 circuit is executed at a phase point, provides an output voltage, the switch closes. The mode of operation of this circuit is as follows: 22. Now the part 17 of the voltage regulator is direct connected to battery 13- 5 power in any part of the circuit. When the closed (instead of the ignition switch 14). When the ignition switch 36 is closed, the control lamp 21 is switched to the conductive state via the resistor 43. State shifted and supplies current to the Feldwickln a modified embodiment (the lung 45th at the same time lights up due to the dashed lines is indicated) the IO current through the resistors 38, 39, the control switch 22 is still used to bypass the first part of the lamp 37 on. If necessary, a 17 of the voltage regulator can be used as long as the generator does not provide an output voltage with additional resistance in parallel with the resistors. The control lamp 38, 39 can be switched to increase the current, 21 is as long as the ignition switch 14 and the flow through the control lamp. When the gene switch 22 is connected to the battery. 15 rator34 supplies voltage, the switch, which in Fig. 2 is in turn a battery 33 formed by the transistor 51, is closed and the motor vehicle to two terminals 31, 32. In this way, the resistors 38, 39 are directly connected to terminals 31, 32 is also a generator 34. the terminals 31, 32 placed. At the same time, consumers 35 that can be fed by the battery go out, the control lamp 37 because it is short-circuited.
are connected to the battery in series with an ignition switch 20 as long as the output voltage of the generator 36 of the motor vehicle. is below a predetermined value, is on terminals 31, 32, in series with the ignition, the Zener diode 41 in a non-conductive state, switch 36, is also a potentiometer chain and the transistor 44 conducts continuously, so that the one permanently connected Control lamp 37 and a field current flowing through the field winding 45, stands 38,39 contains. A point between the 25, however, when the predetermined voltage is reached via a zener diode 41 with resistors 38, 39, the zener diode 41 ignites and conducts a base of the base of an npn transistor 42 connected to the transistor 42, which thereby turns into its Emitter at the terminal 32 and its conductive state is set and the collector is now connected via a resistor 43 in series with the base current, which flows through the transistor 44, from the ignition switch 36 to the terminal 31. The 30 derives from the resistor 43. The circuit arrangement collector of transistor 42 is also connected to the base voltage is therefore switched to a state in which a second npn transistor 44 is connected, of which transistor 42 is conductive and transistor 44 is emitter at terminal 32 and whose collector is non-conductive, so that no current through the field via the field winding 45 of the generator 34 in series winding 45 flows. As a result of the feedback with the ignition switch 36 connected to the terminal 31 via the capacitor 47 and which is closed. A diode 46 is connected in parallel to the field resistor 48, the circuit arrangement is connected in the winding and is used to derive the counter-electrical switching operation, so that a pulsating current in the motor force can be derived. The field winding 45 winding 45 flows. The periods of conductivity can also be connected directly to the terminal 31 (instead of via the transistors 44, 42 through the current through the ignition switch 36). The second 40 is correct, which flows through the Zener diode 41, so that part 18 of the voltage regulator described in Fig. 1, the greater the output voltage of the generator 34 is in Fig. 2 through the circuit of the transistor 44, the less current through the winding 45 formed. The collector of transistor 44 is also flowing.

The F i g. 3 shows an application of the present sator47 in series with a resistor 48 to an electromechanical voltage control regulator. The first part of the regulator is a voltage Em point between the control lamp 37 and the scanning coil 61, which is in series with a control lamp resistor 38 at the collector of a 62 and an ignition switch 63 on the battery 64 pnp transistor 51, whose emitter with the clamp lies.
