Mfundo yogwirira ntchito ndi kugwiritsa ntchito katundu wamagetsi

Electronic load ndi mtundu wa chipangizo chomwe chimagwiritsa ntchito mphamvu yamagetsi poyang'anira mphamvu yamkati (MOSFET) kapena transistors 'flux (duty cycle).Imatha kuzindikira bwino mphamvu yamagetsi, kusintha momwe katunduyo alili, ndikutengera gawo lalifupi.Katundu woyerekedwayo ndi wotsutsa komanso wokwanira, komanso nthawi yokwera ya capacitive yomwe ikukwera.The debugging ndi kuyezetsa wa general switching magetsi n'kofunika.

mfundo yogwirira ntchito

Katundu wamagetsi amatha kutsanzira katundu m'malo enieni.Lili ndi ntchito za nthawi zonse, kukana kosalekeza, voteji nthawi zonse ndi mphamvu zokhazikika.Katundu wamagetsi amagawidwa kukhala DC electronic load ndi AC electronic load.Chifukwa cha kugwiritsa ntchito katundu wamagetsi, pepala ili limayambitsa katundu wamagetsi wa DC.

Katundu wamagetsi nthawi zambiri amagawidwa mumtundu umodzi wamagetsi ndi katundu wambiri wamagetsi.Gawoli limatengera zosowa za wogwiritsa ntchito, ndipo chinthu choyenera kuyesedwa ndi chimodzi kapena chimafunikira mayeso angapo nthawi imodzi.

Cholinga ndi ntchito

Katundu wamagetsi ayenera kukhala ndi chitetezo chokwanira.

Ntchito yodzitchinjiriza imagawidwa kukhala ntchito yoteteza mkati (yamagetsi) ndi ntchito yoteteza kunja (zida zomwe zikuyesedwa).

Chitetezo chamkati chimaphatikizapo: kutetezedwa kwamagetsi, kutetezedwa kwaposachedwa, kutetezedwa kwamagetsi, chitetezo chamagetsi chamagetsi komanso kuteteza kutentha.

Chitetezo chakunja chimaphatikizapo: chitetezo chapano, chitetezo champhamvu, mphamvu yamagetsi ndi chitetezo chamagetsi otsika.
