Description

Chopper electronic stabilizer for magnetic electric motor

The utility model is used for motorcycle and the tractor by the magneto power supply, with the magneto output voltage stabilization, belongs to the traffic technical field of electric appliances.

Existing chopped mode magneto pressurizer, the circuit structure complexity, the load characteristic rotary speed property is poor, adjusts difficulty, and the production difficulty is big.

The purpose of this utility model provides that a kind of circuit is simple, performance good, adjust and be easy to chopped mode magneto electronic voltage regulator.

The utility model is made of bidirectional triode thyristor, sample circuit, circuits for triggering three parts.It is characterized in that sample circuit is made up of the partial pressure type current rectifying and wave filtering circuit, circuits for triggering are made up of a voltage stabilizing didoe.Below in conjunction with drawings and Examples its operation principle is described.

Accompanying drawing 1 is one of no storage battery vehicle pressurizer embodiment;

Accompanying drawing 2 is two of no storage battery vehicle pressurizer embodiment;

Accompanying drawing 3 is that storage battery vehicle pressurizer embodiment is arranged;

Pressurizer shown in Figure 1, BCR forms chopper circuit by bidirectional triode thyristor; D ₁, R ₁, R ₂, C ₁Form the partial pressure type current rectifying and wave filtering circuit; Voltage stabilizing didoe D ₂, R ₃Form circuits for triggering.Operation principle is as follows:

When 2. the magneto output voltage is rectified for 1. end is negative, D ₁Conducting is through R ₁, R ₂, C ₁After the dividing potential drop sampling filtering, 3. producing a pulsating dc voltage, when this voltage during greater than the trigger voltage sum of voltage-stabiliser tube puncture voltage and BCR, the BCR conducting that is triggered, 1. 2. both end voltage by copped wave, form bigger chopper current in magneto and BCR loop, energy mainly consumes on magneto.After this, D ₁End C ₁Pass through R ₂And D ₂Discharge.During magneto output voltage zero passage, BCR ends.1. the magneto output voltage becomes rectifies when 2. end is negative D ₁Still end, because of C ₁Two ends still have certain voltage, therefore when 1. 2. the both end voltage value is higher than a certain numerical value, and the BCR conducting that is triggered again, 1. 2. both end voltage like this, is gone round and begun again again by copped wave, and 1. 2. two ends are output as positive-negative half-cycle all by the voltage of copped wave.The magneto output voltage is high more, C ₁It is fast more to charge, and the BCR ON time is long more, and 1. 2. the positive-negative half-cycle pulse duration of two ends output is narrow more; Otherwise the voltage pulse output width is wide more.Its effect is to make 1. 2. that the two ends average value of output voltage keeps relative stability.

No storage battery vehicle pressurizer shown in the accompanying drawing 2 is on the basis of Fig. 1, seals in resistance R in the capacitor C loop ₄, R ₄Effect be the rotary speed property that improves pressurizer.

Shown in the accompanying drawing 3 storage battery vehicle pressurizer being arranged, is to have increased D on the basis of Fig. 1 ₃, D ₄, D ₅Series connection rectification charging diode and current-limiting resistance R ₅, D ₃, D ₄, D ₅A plurality of diode series connection, the one, being used for controlling initiation of charge voltage headlight when guaranteeing night has enough rated voltages (present the storage battery vehicle to be arranged, the magneto high-voltage output terminal is the charging output, low-voltage output connects headlight), the 2nd, utilize the non-linear restriction charging current of diode.R ₅Also be used for limiting charging current, prevent that storage battery from overcharging.During production, can be according to the performance and the charging requirement of magneto, D ₃, D ₄, D ₅Optional one, two or three, R ₅Optional zero Europe is to 1 Europe.

R shown in the dotted line among Fig. 3 ₄Also be used for improving the rotary speed property of pressurizer, can determine to insert or do not insert according to actual conditions during production.
