Buna ziua. In link-ul de mai sus, imaginea nr.28, se da schema unui incarcator de baterie,dar nu se spune nimic despre aceasta schema.va rog,sa puneti adresa linku-lui,pentru o mai buna intelegere

Schema la care faceti referire este modernizata si descrierea este urmatoarea:

Here are the adjustable type car battery charger, rechargeable 6V ~ 50V adjustable voltage, maximum charge current up to 20A.

Suitable for 12V, 24V, 36V, and other specifications of the car battery. How it works: As shown above, connect the power,

the AC through the transformer primary winding, R1, RP, and R2 to the capacitor C2 charging,

when the voltage on C2 to trigger the two-way turn-on voltage of diode ST, C2 and two-way through the ST SCR BCR discharge,

and trigger the BCR conduction, so that the transformer primary current flows through T, in the alternating current zero crossing,

BCR off, C2 begins charging, repeat the process. Adjustment potentiometer RP, changing the charging time constant of C2,

which changed the triac conduction angle, play the role of electronic voltage regulation, while the secondary voltage

of the transformer T, a corresponding change, changing the charging voltage and charging current.

Circuit, L, C1 SCR pulses to eliminate interference. Transformer T selected power of about 250W. L with a long 30cm,

6mm ferrite cores with? 0.8mm magnet wire around a total of 100 three-point turn.

TRIAC 8A/600V BCR used, equipped with 2mm x 140mm x 80mm aluminum heat sink.

Ammeter A selection of TV range is the 59L1-A-type 20A. Table V voltage range is 50V used TV?s 59C2-V type.

The remaining components of models as shown.

Ca observatie, este singurul tip de schema la care comanda la tiristori sau triaci se face in primarul transformatorului

 si la care este pericol de electrocutare daca nu se utilizeaza potentiometri speciali care rezista la 1000V,

 tensiune de izolatie. Deasemenea este pericol si la masuratori si eventualele reglaje.
