Description

Automatic excitation regulated generator

The utility model belongs to generator, particularly a kind of automatic magnetic exciting stable-voltage generator.

Existing commercially available alternator for vehicle, all be to control its output voltage at the equipped adjuster in the outside of generator, the line of generator and adjuster will increase to the failure rate and the maintenance difficulty of car load like this, and the easy short circuit of magnetic field line, cause adjuster easily to burn, unstable properties, recently also there is external car to use the generator of interior dress adjuster, but it also needs ignition switch, at first provide an initial exciting curent generator ability operate as normal to generator, generator is can operate as normal when the lead that initial exciting curent is provided breaks down, and wastes electric energy like this.

The purpose of this utility model is to provide the automatic magnetic exciting stable-voltage generator of a kind of simple in structure, stable performance, energy-conservation, interior dress adjuster.

Technical solution scheme of the present utility model is such, adjuster is housed in generator, adjuster comprises by amplifying circuit, composite switch circuit, voltage stabilizing regulating circuit, output cathode after the rectification of circuit anode sending and receiving motor, the circuit signal input connects arbitrary phase coil of generator, be connected in series an electric capacity maintenance between a phase coil and the ground in addition in generator triggering signal is provided.Field coil just has exciting curent to pass through when having only generator operation, and generator does not have exciting curent when not turning round, and generator does not generate electricity, thereby plays the voltage stabilizing regulating action.If when using with the automobile assembling that ammeter is arranged, only need connect line of generator armature gets final product operate as normal, therefore, simplifies circuit, reduces fault.

The utility model has the advantages that circuit is simple, energy-conservation, stable performance, cost be low.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the electrical schematic diagram of the utility model adjuster.

Fig. 2 is the electrical schematic diagram of another embodiment of the utility model adjuster.

Among Fig. 1, rectifying tube D1, resistance R 2-R6, triode T1-T5, capacitor C 1, voltage-stabiliser tube W, diode D2, coil LF.Rectifying tube D1, resistance R 1 is serially connected with the T1 base stage, the C utmost point of T1 meets base stage and the R2 of T2, the C utmost point of T2 meets R3, R4, R4 one end connects capacitor C 1 and T3 base stage, T1, the e utmost point ground connection of T2, the e utmost point of T3 connects the T4b utmost point, e utmost point ground connection, T3, the T4C utmost point connects diode D2, coil LF and R6 ground connection, the resistance R 5 of voltage stabilizing regulating circuit, voltage-stabiliser tube W, the T5b utmost point, in the e utmost point sequential circuit, the C utmost point of T5 connects the b utmost point of T3, and the B point connects arbitrary phase of generator in the circuit, and the A point connects the generator commutation output cathode, in addition, electric capacity of serial connection keeps providing triggering signal between the arbitrary phase and ground in generator.

In electrical schematic diagram shown in Figure 1, R6 provides a very little electric current to make it produce a very little magnetic field at first for generator field coil LF, when generator operation, on its armature coil, will produce a very faint electric current, this electric current is through the D1 rectification, deliver to the base stage of T1 by R1, (metering function when R1 mainly is used as normal power generation), make the T1 conducting, T2 ends, the T2 collector voltage raises, the voltage that raises also raises the T3 base voltage through R4, T3 and T4 compound this moment, the T4 conducting, the accumulator positive electrode current is by the C of A point process field coil LF to T4, the e utmost point arrives negative pole again, coil LF has electric current to make generator for electricity generation by producing magnetic field, when the voltage that is sent when the voltage or the generator itself of storage battery is elevated to 14 volts of rated values or 28 volts, electric current will puncture voltage stabilizing didoe W through R5, thereby make T5 base voltage rising T5 conducting, make the T3 base voltage equal zero, T3, T4, cut-off magnetic field coil LF does not have electric current, generator does not generate electricity, and so just plays the voltage stabilizing regulating action.

In another embodiment of Fig. 2, resistance R 1-R6, rectifying tube D1, filter capacitor C1, amplifier pipe ICA, ACB, capacitor C 2, diode D2, D3, triode T1, T2, coil LF.Resistance R 1 in the circuit, D1 are serially connected with amplifier pipe ICA electrode input end, output connecting resistance R2 and capacitor C 2 are to ground, positive pole and D2 that R2 meets ICB arrive ground, negative pole connection divider resistance R3 and R4 at ICB are serially connected with in the circuit, the output termination R5 of ICB and the triode T1b utmost point, the T1e utmost point connects the T2b utmost point, T2e utmost point ground connection, and the C utmost point of T1, T2 meets diode D2, coil LF and arrives ground to positive pole and R6.

Its operation principle shown in Figure 2: when generator operation, the faint alternating current that armature produced is through the D1 rectification, C1 is filtered into normal phase input end that direct current is added to amplifier pipe ICA, and to make its output be high potential, this high potential obtains the reference voltage of a 0.7V through resistance R 2 and diode D2, be added to the normal phase input end of amplifier pipe ICB, because the bleeder circuit that R3 and R4 formed is not when rated voltage has superelevation, the current potential of the inverting input of ICB is lower than the current potential of reference voltage 0.7V, at this moment the output of amplifier ICB is high voltage output, the combination switch pipe conducting that T1 and T2 form, generator for electricity generation, when voltage is higher than rated value, the dividing point that R3 and R4 formed is higher than 0.7 volt of reference voltage, and the anti-skill of amplifier pipe ICB is transferred out electronegative potential, and T1 and T2 end, generator does not generate electricity, thereby plays the voltage stabilizing regulating action.
