Unikezelo lwamandla njengamacandelo okuhanjiswa kwezixhobo zombane, ukongeza kwiimpawu zokuqwalasela izibonelelo zenkqubo yokubonelela ngombane, amanyathelo alo okukhusela nawo abaluleke kakhulu.kubalulekile, njenge-over-current, over-voltage, over-temperature maintenance. Nje ukuba unikezelo lwamandla lungenayo inkqubo yoyilo lokhuseleko olugqithileyo, kwisiphumo sokungaphumeleli kwesekethe emfutshane okanye ukugcwala kuya kubangela umonakalo kunikezelo lwamandla, kodwa kunokwenzeka ukuba kubangele ngakumbi.intshabalalo yezixhobo ze-elektroniki, kwaye nokuba kubangele ukusebenza kwabasebenzi bengozi yombane kunye nomlilo kunye nezinye iingozi zokhuseleko, kunye nokhuseleko oludlulayo lonikezelo lombane ngokusetyenziswa kombane.Ii-MOSFETs ezinxulumene.
Ukuyibeka ngokungqongqo ukhuseleko lwe-overcurrent, lukwimveliso yeempazamo zesekethe ezimfutshane okanye umthwalo ogqithisiweyo kunikezelo lwamandla okanye ukugcinwa komthwalo, kweli nqanaba lonikezelo lwamandla okhuseleko lwe-overcurrent kukho iindlela ezahlukeneyo, ezinje ngokuqhubekayo-yangoku, ukuphuma rhoqo. uhlobo lwamandla, njl.njl., kodwa uphuhliso lwesekethe yokhuseleko lwe-overcurrent alunakwahlulwa kwi-MOSFET, i-MOSFETs ekumgangatho ophezulu inokuphucula indima yonikezelo lwamandla ukhuseleko olungaphaya.
