Izizathu kunye neendlela zonyango overcurrent xa izixhobo zokufudumeza eziphezulu ivuliwe

Izizathu zexesha elidluleyo ekuqaleni:

1. Ukuqhekeka kwe-IGBT.

2. Ibhodi yokuqhuba iphosakele.

3. Ibangelwa yibhalansi yeringi encinci yamagnetic.

4. Ibhodi yesekethe imanzi.

5. Umbane webhodi yabaqhubi awuqhelekanga.

6. Inzwa ifutshane-ijikelezwe.

Indlela yokucubungula i-overcurrent ekuqaleni:

1. Faka indawo yebhodi yokuqhuba kunye ne-IGBT, susa i-ring magnetic encinci kwi-lead, khangela umzila wamanzi kunye nokuba ibhokisi yamanzi ivaliwe, vuthela ibhodi esetyenzisiweyo ngesomisi seenwele, kwaye ulinganise i-voltage;

2. I-Overcurrent emva kokusetyenziswa kwithuba lexesha emva kokuqalisa: Isizathu ngokubanzi kukuchithwa kakubi kobushushu bomqhubi. Indlela yonyango: Faka kwakhona igrisi ye-silicone; khangela ukuba indlela yamanzi ivaliwe na.
