regulator tip shunt pentru instalatii eoliene,solare, etc

Recommended Posts

va propun o schema simpla pentru reglarea tensiunii pentru acumulator de 12V.am montat-o la o instalatie eoliana si functioneaza perfect de 3 luni de zile.dupa cum se observa in schema,avem un zener de precizie TL431 si un 555 care scoate un semnal pwm.intr-un domeniu de 0,5V de la tensiunea reglata,avem intreaga tensiune disipata pe rezistenta Rschema se poate inbunatatii prin montarea unui driver de mosfet si legarea mai multora in paralel,daca se doreste reglarea unor curenti curenti mai mari.personal,am folosit o rezistenta de 15A la 12V.recomand si montarea unei diode paralel pe rezistenta daca aceasta va fi bobinata(si cred ca va fi)
