Ukugcinwa kwamandla kubhekisela enkambisweni yokujikeleza yokugcina amandla ngokusebenzisa indlela noma idivayisi bese iwakhipha uma kudingeka esikhathini esizayo. Izinhlelo zokugcina amandla zidlala indima ebalulekile ezinhlelweni zamandla ezintsha zesimanje. Ama-inverter okugcina amandla adlala indima yokuguqulwa kwamandla, ukulawula kanye nokuxhumana ohlelweni, kanye nokushaja nokukhipha amandla ngezindlela ezimbili ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamandla.
Ama-converter okugcina amandla ngokuvamile aqukethe i-input end, i-output end kanye nesistimu yokulawula. Uma kusebenzisana negridi yamandla, ama-capacitor anomthamo omkhulu, ukumelana nokushaqeka okukhulu kwamanje, kanye ne-ESR ephansi asetshenziswa kakhulu ukwenza imisebenzi efana nokuzinza kwe-voltage kanye nokuhlunga, ukugcinwa kwamandla kanye nokukhululwa ukuze kube nokushaya kwe-DC okubushelelezi, ngaleyo ndlela kwandisa ukusebenza kahle kwe-converter kanye nokuqina kokusebenza kwesistimu yokugcina amandla, kanye nokuvikela i-converter lapho ihlangabezana nezimo zokusebenza ezingavamile.
1. Ubuningi be-capacitance ephezulu
Ama-capacitor efilimu ye-MDPzinezimpawu zobuningi be-capacitance ephezulu, okubalulekile ukuthi i-PCS igcine ukukhishwa kwe-voltage okuzinzile ngesikhathi sokuguqulwa kwamandla. Emithwalweni efana nama-motor, abhekene nesidingo samandla, ama-capacitor efilimu ahlinzeka ngesinxephezelo samandla asabelayo, aqinise i-voltage, futhi athuthukise ukusebenza kahle kwama-motor, ngaleyo ndlela athuthukise ukusebenza kahle kwamandla kanye nokuzinza kwezinhlelo zokugcina amandla.
2. Ukuthembeka okuphezulu nokuphila isikhathi eside
Uma kuqhathaniswa nama-capacitor e-aluminium electrolytic endabuko, ama-capacitor efilimu e-YMIN anempilo ende yesevisi kanye nokuthembeka okuphezulu. Akulula ukuguga, anokumelana okuhle nokushisa okuphezulu, futhi angasebenza ngokuzinzile isikhathi eside ngaphansi kwezimo zemvelo ezinzima. Lokhu kubaluleke kakhulu ekusebenzeni okuzinzile kwe-PCS ezindaweni ezahlukahlukene eziyinkimbinkimbi.
3. Ukumelana kwamanje okugobhozayo
Ama-capacitor efilimu ye-MDP angasetshenziswa ukuhlunga, ukunciphisa ububanzi bemvamisa yezibonakaliso noma ukunciphisa umsindo kumasignali. Ku-PCS, kusiza ukunciphisa umsindo wemvamisa ephezulu kanye ne-ripple ekhiqizwa ngesikhathi sokuguqulwa kwamandla, ukuthuthukisa ikhwalithi yamandla, futhi kungasetshenziswa njengedivayisi yokuxhumanisa ukudlulisa amasignali ahlukene kumasekethe ahambisanayo, ngaleyo ndlela kufezekiswe ukusebenzisana kwedatha kanye nokudluliswa kwamasignali. Ngaphezu kwalokho, ingasebenza futhi njengesekethe ye-buffer, imunce futhi icindezele ukuphazamiseka kwesikhashana kanye nomsinga womthelela kusekethe, ivikele ezinye izingxenye ze-elekthronikhi ekulimaleni.
02 Ukukhetha i-capacitor yefilimu okunconywayo
Imikhiqizo yephini evamile, i-ESR ephansi, imikhiqizo engu-105℃ engu-100000H
03 Isifinyezo
Ama-capacitor efilimu ye-YMIN MDPzinezinzuzo zobuningi bomthamo ophezulu, ukumelana nogesi ogelezayo, ukuthembeka okuphezulu, kanye nokuphila isikhathi eside. Zisiza abaguquli be-PCS ukuguqula i-AC ne-DC futhi ziqedele inqubo yokugeleza kwamandla okuqondiswa kabili. Ngesikhathi esifanayo, zinganciphisa iziqongo futhi zigcwalise izigodi ukuze kuthuthukiswe ukusebenza kahle kokusetshenziswa kwamandla, kuvinjelwe ukugcwala ngokweqile futhi kuqinisekiswe ukuphepha kohlelo. Zibaluleke kakhulu ekuthuthukiseni ukuphepha, ukuzinza kanye nokusebenza kahle kwezinhlelo zokugcina amandla. Ngokuthuthuka okusheshayo kwezinhlelo zokugcina amandla emkhakheni wamandla amasha, amathuba okusetshenziswa kwama-capacitor efilimu azoba maningi.
