Ingxenye yokulungiswa kwamandla idlala indima ebalulekile emishinini yokushisela indawo yokugcina amandla ngokuguqula amandla wamanje (AC) ashintshanayo asuke epayipini elihambisa amanzi abe namandla amanje aqondile (DC) afanele ukushaja isistimu yokugcina amandla. Lesi sihloko sinikeza ukubuka konke komsebenzi nokubaluleka kwesigaba sokulungiswa kwamandla emishini yokushisela indawo yokugcina amandla, igqamisa indima yayo ekuqinisekiseni ukusebenza kahle nokuthembekile.
- Ukuguqulwa kwamandla: Isigaba sokulungiswa kwamandla sinesibopho sokuguqula amandla e-AC abe amandla e-DC. Isebenzisa ama-rectifier circuits, afana nama-diode noma ama-thyristors, ukulungisa i-wave wave ye-voltage ye-AC engenayo, okuholela ku-pulsating DC waveform. Lokhu kuguqulwa kubalulekile ngoba isistimu yokugcina amandla ngokuvamile idinga amandla e-DC ukuze ishaje futhi ikhiphe imisebenzi.
- I-Voltage Regulation: Ngaphezu kokuguqula amandla e-AC abe yi-DC, isigaba sokulungisa amandla siphinde senze ukulawulwa kwamandla kagesi. Iqinisekisa ukuthi amandla kagesi alungisiwe e-DC ahlala ebangeni elifunekayo ukuze ahlangabezane nezimfuneko zesistimu yokugcina amandla. Ukulawulwa kwamandla kagesi kufinyelelwa ngezindlela zokulawula, njengamasekhethi empendulo kanye nezilawuli zikagesi, eziqapha futhi zilungise ugesi ophumayo ngokufanele.
- Ukuhlunga Nokusheshisa: I-waveform ye-DC elungisiwe ekhiqizwe yisigaba sokulungiswa kwamandla iqukethe i-ripple engafuneki noma ukuguquguquka. Ukuze kuqedwe lokhu kuguquguquka nokuthola ukuphuma okubushelelezi kwe-DC, kusetshenziswa izingxenye zokuhlunga nokushelela. Ama-Capacitor nama-inductors avame ukusetshenziselwa ukuhlunga izingxenye zamafrikhwensi aphezulu kanye nokunciphisa ukugeleza kwamandla kagesi, okuholela ekunikezeni kwamandla kagesi we-DC ozinzile nokuqhubekayo.
- Ukulungiswa kwe-Power Factor (PFC): Ukusetshenziswa kahle kwamandla kuyisici esibalulekile semishini yokushisela indawo yokugcina amandla. Isigaba sokulungiswa kwamandla ngokuvamile sihlanganisa amasu okulungisa isici samandla ukuze kuthuthukiswe ukusebenza kahle kwamandla nokunciphisa ukumoshakala kwamandla. Amasekhethi e-PFC alungisa isici samandla ngenkuthalo ngokulungisa i-waveform yamanje yokufaka, iqondanise ne-voltage waveform, kanye nokunciphisa ukusetshenziswa kwamandla okusebenzayo.
- Ukuthembeka Nokuphepha Kwesistimu: Isigaba sokulungiswa kwamandla sihlanganisa izici zokuphepha nezindlela zokuvikela ukuze kuqinisekiswe ukusebenza okuthembekile nokuphephile komshini wokushisela. Ukuvikelwa kwe-overvoltage, ukuvikelwa kwe-overcurrent, nokuvikelwa kwe-short circuit kuyasetshenziswa ukuze kuvikelwe izingxenye zokulungisa futhi kuvimbele ukulimala ohlelweni. Lezi zinyathelo zokuphepha zifaka isandla ekuthembekeni okuphelele nasekuphileni isikhathi eside kwemishini.
Ingxenye yokulungiswa kwamandla idlala indima ebalulekile emishinini yokushisela indawo yokugcina amandla ngokuguqula amandla e-AC abe amandla e-DC alawulwayo nahlungiwe ukuze ashaje isistimu yokugcina amandla. Ngokwenza ukuguqulwa kwamandla, ukulawulwa kwamandla kagesi, ukuhlunga, nokushelela, kanye nokuhlanganisa ukulungiswa kwezinto zamandla kanye nezici zokuphepha, lesi sigaba siqinisekisa ukusebenza kahle nokuthembekile komshini wokushisela. Abakhiqizi bayaqhubeka nokuthuthukisa ubuchwepheshe bokulungisa amandla ukuze kuthuthukiswe ukusebenza kahle kwamandla, ukuthuthukisa ikhwalithi yamandla, nokugcina izinga eliphezulu lokuphepha ezinhlelweni zokushisela indawo yokugcina amandla.
