Ukugcinwa kwamandla kubhekisa kwinkqubo ejikelezayo yokugcina amandla ngesixhobo okanye isixhobo kwaye siwakhuphe xa kufuneka kwixesha elizayo. Iinkqubo zokugcina amandla zidlala indima ebalulekileyo kwiinkqubo zamandla ezintsha zanamhlanje. Ii-inverters zokugcina amandla zidlala indima yokuguqulwa kwamandla, ulawulo kunye nonxibelelwano kwinkqubo, kunye nokutshaja nokukhupha amandla kwicala ngalinye ukuphucula ukusebenza kakuhle kwamandla.
Ii-converter zokugcina amandla zihlala ziquka isiphelo sokufaka, isiphelo sokukhupha kunye nenkqubo yokulawula. Xa kusebenzisana negridi yamandla, ii-capacitors ezinomthamo omkhulu, ukumelana noxinzelelo olukhulu lwamandla, kunye ne-ESR ephantsi zisetyenziselwa ikakhulu ukwenza imisebenzi efana nokuzinzisa i-voltage kunye nokucoca, ukugcinwa kwamandla kunye nokukhululwa kwi-DC pulsations egudileyo, ngaloo ndlela kwandisa ukusebenza kakuhle kwe-converter kunye nokuzinza kokusebenza kwenkqubo yokugcina amandla, kunye nokukhusela i-converter xa idibana neemeko zokusebenza ezingaqhelekanga.
1. Uxinano oluphezulu lwe-capacitance
Ii-capacitor zefilimu ze-MDPzineempawu zoxinano oluphezulu lwe-capacitance, nto leyo ibalulekileyo kwi-PCS ukugcina umbane ozinzileyo ngexesha lokuguqulwa kwamandla. Kwimithwalo efana neemoto, ezijongene nemfuno yamandla, ii-capacitors zefilimu zibonelela ngembuyekezo yamandla asabelayo, zizinzise i-voltage, kwaye ziphucula ukusebenza kakuhle kweemoto, ngaloo ndlela ziphucula ukusebenza kakuhle kwamandla kunye nokuzinza kweenkqubo zokugcina amandla.
2. Ukuthembeka okuphezulu kunye nobomi obude
Xa kuthelekiswa nee-capacitors ze-aluminium electrolytic zemveli, ii-capacitors zefilimu ze-YMIN zinobomi obude benkonzo kunye nokuthembeka okuphezulu. Akulula ukuguga, zinokumelana kakuhle nobushushu obuphezulu, kwaye zinokusebenza ngokuzinzileyo ixesha elide phantsi kweemeko ezinzima zendalo. Oku kubaluleke kakhulu ekusebenzeni okuzinzileyo kwe-PCS kwiindawo ezahlukeneyo ezintsonkothileyo.
3. Ukumelana nomsinga we-Ripple
Ii-capacitor zefilimu ze-MDP zingasetyenziselwa ukucoca, ukunciphisa uluhlu lwemvamisa yemiqondiso okanye ukunciphisa ingxolo kwiisignali. Kwi-PCS, inceda ukunciphisa ingxolo yemvamisa ephezulu kunye ne-ripple eveliswa ngexesha lokuguqulwa kwamandla, ukuphucula umgangatho wamandla, kwaye ingasetyenziswa njengesixhobo sokudibanisa ukuhambisa imiqondiso eyahlukeneyo kwiisekethe ezifanelekileyo, ngaloo ndlela ifezekisa ukusebenzisana kwedatha kunye nokudluliselwa kwesignali. Ukongeza, ingasebenza njengesekethe ye-buffer, ifunxa kwaye icinezele ukuphazamiseka okwethutyana kunye nomsinga wempembelelo kwisekethe, ikhusela ezinye izinto ze-elektroniki ekonakaleni.
02 Ukhetho olucetyiswayo lwe-capacitor yefilimu
Iimveliso zepini eziqhelekileyo, i-ESR ephantsi, iimveliso ze-105℃ ze-100000H
03 Isishwankathelo
Ii-capacitor zefilimu ze-YMIN MDPZineengenelo zobuninzi bomthamo ophezulu, ukumelana nombane ojikelezayo, ukuthembeka okuphezulu, kunye nobomi obude. Zinceda abaguquli be-PCS ukuguqula i-AC kunye ne-DC kunye nokugqibezela inkqubo yokuhamba kwamandla okuhamba ngamacandelo amabini. Kwangaxeshanye, zinokunciphisa iincopho kwaye zizalise iintlambo ukuphucula ukusebenza kakuhle kokusetyenziswa kwamandla, ukuthintela ukugqithisa kunye nokuqinisekisa ukhuseleko lwenkqubo. Zibaluleke kakhulu ekuphuculeni ukhuseleko, uzinzo kunye nokusebenza kakuhle kweenkqubo zokugcina amandla. Ngophuhliso olukhawulezileyo lweenkqubo zokugcina amandla kwicandelo lamandla amatsha, amathuba okusetyenziswa kwee-capacitors zefilimu aya kuba banzi.
