Kuyilo lwezixhobo ze-elektroniki, ukukhetha amandla okhuseleko kubalulekile, ngakumbi ingqalelo kufuneka ihlawulwe kwiindlela zabo zokungaphumeleli kunye nevoldage yokumelana nezalathiso.Eyona ndlela ixhaphakileyo yokuyeka amandla ezokhuseleko kukusilela kwi-voltage ephantsi, ehambelana kakhulu nomda wokhuseleko kwiyilo labo.Ukusuka kwimbonosela okhuselo, abaqulunqisi zihlala zithanda ukukhetha amandla kunye nomda omkhulu wokhuseleko kwithemba lokuba ukusilela kwethemba akuyi kukhokelela ekungaphumeleli ekuhlaleni.Nangona kunjalo, le ndlela inokuba neempazamo.
Iimpawu eziphambili zokungaphumeleli kwe-voltage ephantsi zibandakanya: Eyona voltage isetyenzisiweyo iphantsi kakhulu kunexesha elinqandisiweyo kwixabiso le-capacitor, ngesiqhelo kungekho ngaphezulu kwe-10% yexabiso elingaphezulu kwexabiso;I-capacitor ithambekele ekubeni ingaphumeleli emva kovavanyo olushushu noluHid okanye ukuqina komswakama;I-Capacitor ithambekele ekubeni singaphumeleli emva kovavanyo lobushushu obuphezulu okanye ukubhaka kwebhodi yesekethe.I-capacitor iya kubuyela esiqhelekileyo;Intsebenzo ye-capacitotor iya kubuyiselwa kwakhona emva kokuba isuswe kwiBhodi yeSiphaluka kunye ne-voltage ephezulu kune-voltage eqhelekileyo esetyenziswayo.Ezi zinto zibonisa ukuba ukusilela kwe-voltage ephantsi kwe-capecitors yezokhuseleko yingxaki efanele ukuhoywa.
Isizathu sokungaphumeleli kwe-voltage esezantsi kukuba i-Medium ekwi-Medium ekwimo yeCawa yoKhuseleko iqhutywa yi-Cheary, kwaye ezi zinto zingatywinwa zitywiniwe ngokupheleleyo, oko ke kubonelela ngethuba lokufumana umbandela wokufuma.Umzekelo, ukufumana i-Canocitor yokhuseleko kunye ne-voltage ye-50V, xa i-voltage ye-5V isetyenziswa kuzo zombini iziphelo, umswakama kwindlela ephakathi ye-leakege.Ngenxa ye-voltage ephantsi, ukuvuza okwangoku akuyonto kwaye amanzi engenakuchithe, ngaloo ndlela atshabalalisa iimpawu zokugcina amandla eCapacitoti.Nangona kunjalo, kumaqondo obushushu aphezulu okanye xa kusetyenziswa i-voltage ephezulu, i-vapor yamanzi ikhutshiwe, ebangela ukuvuza indlela yangoku yendlela yokuyinyamalala kunye nokunganyanzelekanga ukuba ibuyele kwisiqhelo.
Ke ngoko, xa ukhetha ii-candlacitors zezokhuseleko, i-Indertages ye-Indetsion akufuneki isekwe kakhulu.Eli lingo eliphambili elithambekele kwiingxaki ekukhetheni.Amandla okhuseleko asetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki, kunye nomgangatho wabo wemveliso ochaphazela umgangatho wethu wobomi kunye nokhuseleko.Xa ukhetha amandla okhuseleko, kuya kufuneka unikezele kwiimveliso zokwenene kumzi-mveliso wokuqala kwaye uqiniseke ukuba zineziqinisekiso zokhuseleko ezivela kumazwe ahlukeneyo ukuqinisekisa ukuba umgangatho wabo kunye nokhuseleko lwabo.
