Description

Voltage regulator permanent-magnet ac generator for automobile

The utility model relates to a kind of voltage regulator, particularly a kind of automobile permanent magnet alternator voltage regulator.

A kind of " silicon rectifier permanent magnet car generator voltage controller " disclosed in the Chinese patent (patent No. 92229405.4), it is to utilize existing electromagnetism shape mechanical oscillation adjuster improved, control the wherein break-make of a winding of alternator frame by the mechanical contact break-make, reach the purpose of control output of a generator.But it has the following disadvantages: control characteristic is poor during (1) this adjuster underloading, although wherein a winding is not worked, when generator speed is high, behind the two-phase voltage commutation still much larger than the voltage stabilizing value that is provided with; (2) during heavy load, wherein a winding mechanical contact flows through interrupted big electric current, and reliability and contact endurance are all low; (3) volume is big, can not make built-in type all-in-one car generator.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and the automobile permanent magnet that a kind of control performance is good, volume is little, circuit is simple and reliable alternator voltage regulator is provided.

The purpose of this utility model can reach by following measure: the utility model comprises sampling comparison circuit, storage battery, generator, housing, it is characterized in that: also have thyristor gating circuit, controllable silicon positive semi-controlled bridge rectifier circuit altogether, the output signal of sampling comparison circuit is delivered to thyristor gating circuit, the triggering signal of thyristor gating circuit output is delivered to controllable silicon positive semi-controlled bridge rectifier circuit altogether, and the controllable silicon output of positive semi-controlled bridge rectifier circuit altogether joins with generator and storage battery.

The purpose of this utility model can reach by following measure: electronic circuit board is housed in the housing, and its lead-out wire is drawn by wire hole.Emitter-base bandgap grading and the voltage-stabiliser tube DW1 of triode BG1 join in the sampling comparison circuit, collector electrode joins by triode BG2 base stage in resistance R 4 and the thyristor gating circuit, the emitter-base bandgap grading of BG2 and voltage-stabiliser tube DW2 join, collector electrode joins by resistance R 7 and triode BG3 base stage, the collector electrode of BG3 joins by the control utmost point of controllable silicon SCR 1～SCR3 in diode D1～D3 and the common positive semi-controlled bridge rectifier circuit of controllable silicon respectively, the negative electrode of SCR1～SCR3 and the winding of generator join, and join by diode D4～D6 and battery positive voltage respectively, the anode of SCR1～SCR3 joins, and joins with the negative pole of storage battery 4.

Fig. 1 is a functional-block diagram of the present utility model;

Fig. 2 is a contour structures schematic diagram of the present utility model;

Fig. 3 is an electrical schematic diagram of the present utility model.

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

Positive semi-controlled bridge rectifier circuit 1, thyristor gating circuit 2, sampling comparison circuit 3, storage battery 4, generator 5, housing 6 etc. are formed altogether by controllable silicon with reference to Fig. 1, Fig. 2 the utility model.Thyristor gating circuit 2, sampling comparison circuit 3 are loaded on the electronic circuit board, and electronic circuit board is loaded in the housing 6, wire hole 7 from housing 6 is drawn three lead-in wires, and the positive pole with the anode of controllable silicon SCR 1～SCR3, control grid and triode D1～D3 joins respectively.

With reference to Fig. 3, controllable silicon positive semi-controlled bridge rectifier circuit 1 altogether comprises controllable silicon SCR 1～SCR3, diode D1～D6 etc.; Thyristor gating circuit 2 comprises triode BG2, BG3, resistance R 4～R7, voltage stabilizing didoe DW2 etc.; Sampling comparison circuit 3 comprises triode BG1, resistance R 1～R3, voltage stabilizing didoe DW1 etc.

During initial condition, automobile storage battery 4 places in circuit, electric current flow through be knot, the DW2 of R3, R4, BG2, the BG2 conducting, the BG3 base stage obtains bias voltage, the BG3 conducting, and controllable silicon SCR 1～SCR3 grid obtains trigger voltage and conducting, bridge rectifier D4～D6 has voltage output, and storage battery 4 is recharged; Load is connected in parallel on storage battery 4 two ends, but also electricity consumption.If BG3 does not end, power output is carried out always.When the voltage charging of storage battery during to certain value, through R1, R2 sampling dividing potential drop, the voltage stabilizing value that the BG1 base potential is higher than be serially connected with voltage-stabiliser tube DW1 on the emitter, the BG1 conducting, the integrated electrode potential of BG1 is approximately equal to DW1 voltage stabilizing current potential; Again because of the voltage-stabiliser tube DW2 value that is serially connected in the BG2 emitter value greater than DW1, so BG2 ends during the BG1 conducting, BG3 also ends, and controllable silicon SCR 1～SCR3 turn-offs, D4～D6 no-output voltage.When the load electricity consumption makes that the terminal voltage of storage battery drops to certain value, BG1 can end again, BG2, BG3 conducting, D4～D6 has voltage output, to storage battery 4 chargings, go round and begin again, thereby make the voltage (being the load utilization voltage) of storage battery two ends be maintained at forever on the required voltage of setting.

The utility model has following advantage compared to existing technology: the control pressure regulating performance is good, and circuit is simple and reliable, and cost is lower, and volume is little, can be made into built-in type all-in-one car magneto.
