Ai masurat semnalul G-E de dupa driver, si igbt-urile ?

Aceiasi "orezarie" am si eu pe masa de lucru: Stern WM 185 INVA, problema a fost igbt-urile pocnite si un condensator devalorizat de pe placuta driver.

Aia da, insa eu am fost curios deoarece am schimbat o data in ceva SMPS in loc de unu pe celalalt si totul a fost OK.

Sa nu ma intrebati care pe care, a fost acu vreo 10 ani.

De aia am intrebat.

Sint convins ca fac indivizii minarii, la ala galben a meu au cam ras denumirea integratelor.

Cumva, cumva am deslusit codul lor.

Mai trist e cind gasesti rulmenti cu dimensiuni pe care doar la ei ii poti comanda...
