    Three resistors (16, 17, 18) connect a point (19) to the output terminals of an alternator stator winding (10). The said point (19) is connected to the positive terminal of the battery (12) through a resistor (20) and to its negative terminal through a zener diode (34) and a resistor (35). A pair of comparators (21, 22) having their outputs connected to the base of a Darlington transistor (28, 30) detect if the voltage at the said point (19) is outside a predetermined range. The junction of the zener diode (34) and its associated resistor (35) is also connected to the base of the Darlington transistor (28, 30). A waning lamp (32) connected in tho collector circuit of the Darlington transistor is energised if the alternator does not produce an output or a malfunction occurs in the charging system.

    This invention relates to signal lamp devices for vehicle charging systems.
    The purpose of the invention is to expand the display range.
    FIG. 1 is an electrical diagram of a device for a charging system with a three-phase alternator, FIG. 2 is a diagram
    devices for charging system with a single-phase generator with a split winding.
    The device contains a resistor circuit, including resistors 1-3, connected at one end to a generator with a stator core 4 with a stator winding 4 and excitation winding 5, supplied from a regulator, which turns on and off the excitation current according to an instantaneous battery voltage battery 7 connected to winding 4 through a three-phase full-period rectifier consisting of diodes 8. The rectifier does not have the usual additional output tap to power the excitation winding 5, but it is connected to battery 7 9 ignition lock of the vehicle.
    The controller 6 is connected to the battery 7 via the lock 9, however, other connections can be used, for example, shown by the dotted line in FIG. one ,
    The other ends of the resistors 1 - 3 are interconnected and connected to the positive terminal of the battery 7 through the resistor 10. The resistances of the resistors 1 - 3 are equal, and the resistor 10 is selected as high-resistance and influential only in the mode when the generator does not produce a current, connection points of resistors 1 - 3 to the positive potential of the battery 7.
    The combined ends of the resistors 1 to 3 are connected to one of the inputs of one comparator 11 voltages and the input of the other comparator 12 of the comparator unit. A series of resistors 13-15 is connected in series between the positive terminal of the battery 7 and the ground, while the resistance value of the resistor 14 is greater than the resistors 13 and 15, the resistances of which are equal. The common point of resistors 13 and 14 is connected to another input of comparator 12. The outputs of both comparators are connected

    The anodes of the respective diodes 16 and 17, the cathodes of which are interconnected and connected through a resistor 18 to the transistor node 19, turn on 5 a signal lamp 20 connected in series with the resistor 21. The node 19 consists of darlington transistors. The emitter of the first transistor of this pair is connected to the base
    10 of the second transistor, the emitter of which is connected to ground. At the input of the node 19, there is a capacitor 22 connected between the cathodes of the diodes 16 and 17 and the ground.
    15 The common connection point of resistors 1 - 3 is connected to earth through a series-connected diode 23 and resistor 24. The diode 23 of the diode is also connected to the base of the first transistor of the node 19. The capacitor 22 can be completely discharged through resistors 18 and 24.
    In normal operation, the voltage at the junction of resistors 1 - 3
    25 varies between two third and one third voltage of battery 7 with a frequency dependent on the speed of rotation of the generator.
    Under these conditions, stress
    The JQ of this point is within the voltages set by the resistors 13-15, with the result that the comparator output voltages remain low.
    The voltage of the diode 23 is more than 2/3 of the battery voltage, therefore, it does not pass the current, and the capacitor 22 remains discharged and the node 19 is not turned on.
    If there is a break in one (or two) of the generator phases, the remaining phases will be broken and the voltage at the junction of resistors 1 - 3 will go beyond the specified limits. When it exceeds 2/3 of the battery voltage, or falls below 1/3 of this voltage, the voltage at the output of the corresponding parameter 1 1 or 12 will increase, charging the capacitor 22 and including node 19. The lamp 20 at the same time will be constantly lit, because the capacitor 22 is discharged relatively slowly through the resistor 18.
     If the generator does not produce a current, for example, when the engine is stopped or as a result of a break in the field winding,

    a brush or a regulator, the resistor 18 causes a voltage rise at the junction point of the resistors 1 to 3, including the comparator 12 and the ignition lamp 20.
    If a short circuit occurs in the controller 6, as a result of which the excitation current goes on continuously, the signal amplitude at the specified point will increase and the lamp 20 will turn on during half the period of the output voltage of the alternator and the diode 23 and resistor 24, however The lamp 20 will continue to burn, because in the absence of the excitation current, the generator does not produce a current and the transistors of the node 20 will be turned on through diode 23. If leakage of the battery current does not create big problems, the comparators 11 and 12 can be connected directly to the battery. ,
    The stator or root winding 4 (Fig. 2) consists of two parts, the common point of which is connected to the positive terminal of the battery 7, and the ends

    they are connected to the cathodes of diodes 25 and 26, the anodes of which are grounded.
    Resistors 1 and 2 are connected at one end with the anodes of the respective diodes 26 and 27, and their other ends are connected and connected via a diode 23 and resistor 24 to ground. In parallel with this circuit, a capacitor 28 is connected.
    The circuit of the resistors 13-15 creates the reference voltages for the comparators 11 and 12. In this case, the resistances of the resistors 13 and 15 are equal in magnitude.
    Any voltage deviation beyond the specified limits (Fig. 1) leads to an increase in one or the other of the comparator output voltage, as a result of which a light bulb is turned on. Capacitor 28 increases the noise immunity of the circuit, especially at low speeds, when the waveform at the junction of resistors 1 and 2 approaches sinusoidal.
