Sursa coboratoare de tensiune - chopper buck


Recommended Posts

Salutare...as vrea sa construiesc o sursa, cu cun controller PWM, sursa sa scoata undeva la 150V, din tensiunea redresata de la retea...partea de forta va fi cu un IGBT de 75A/600V, insa as vrea sa cer o parere in ceea ce priveste controllerul....Controllerul as vrea sa dispuna si de control curent, adica sa limiteze undeva la 20A....iar la un curent de 30A(asta daca se poate, daca nu o fac cu cu un operational sau comparator) sa intre in avarie...frecventa sa fie setabila(20KHz)...

Ca o completare....sursa va fi fara izolare galvanica, adica punte redresoare+condensatori....

Astept niste sugestii daca se poate....multumesc
