Isilawuli sokushintshwa kwe-DC DC
Emhlabeni oguquguqukayo wama-elekthronikhi, isidingo sokuguqulwa kwamandla okusebenzayo nokuthembekile sihlala siyinkinga enkulu.Njengoba izinto zikagesi ziba nzima kakhulu futhi zilambe amandla, isidingo sezixazululo ezithuthukisiwe zokulawulwa kwamandla kagesi sicindezela kakhulu kunangaphambili.Kulapho izilawuli zokushintsha ze-DC DC zingena khona obala, zinikeza izixazululo zempumelelo ukuhlangabezana nezidingo ezihlala zishintsha zezinhlelo zokuguqula amandla zanamuhla.
I-DC DC switching regulator iyisiguquli samandla esisebenzisa isekethe yokushintsha ukuze ilawule kahle futhi iguqule i-DC voltage isuka kwelinye izinga iye kwelinye.Lobu buchwepheshe obuyingqayizivele buvumela ukusebenza kahle okuphezulu kanye nokulawulwa kwamandla kagesi okunembayo, okubenza bufaneleke ezinhlelweni ezisukela kuzinto zikagesi eziphathwayo zabathengi ukuya ezinhlelweni zezimboni eziyinkimbinkimbi.
Inzuzo eyinhloko yezilawuli zokushintsha ze-DC DC ukusebenza kwazo okuhle kakhulu.Izilawuli zomugqa zendabuko zihlushwa ukushabalala kwamandla okubalulekile, kodwa izilawuli ezishintshayo zenza lokhu ngokuvula nokuvala ngokushesha i-voltage yokufaka.Lobu buchwepheshe bunciphisa ukusetshenziswa kwamandla kuyilapho kugcinwa i-voltage ephumayo ezinzile, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwamandla nokunciphisa ukukhiqizwa kokushisa.Ngenxa yalokho, okokusebenza kwe-elekthronikhi okunikwa amandla yizilawuli ezishintshayo kuvame ukuhlala isikhathi eside futhi kusebenza ngokwethembeka.
Esinye isici esiphawulekayo sezilawuli zokushintsha ze-DC DC amandla azo okusingatha izinhlobonhlobo zama-voltages okufakwayo.Ngokungafani nezilawuli zomugqa, ezidinga amazinga kagesi okufakwayo asondele kakhulu ukuze kugcinwe ukulawulwa okunembile, izilawuli ezishintshayo zingamukela ububanzi obubanzi bamandla kagesi.Lokhu kuguquguquka kwenza kube nokwenzeka ukusebenzisa imithombo yamandla ehlukene, njengamabhethri, amaphaneli elanga, ngisho nezinhlelo zamandla ezimoto, ngaphandle kwesidingo sokujikeleza okwengeziwe.
Izilawuli zokushintsha ze-DC DC nazo zinhle ekunikezeni ukulawulwa kwamandla kagesi okuphumayo, ngisho nangaphansi kwezimo zomthwalo ezihlukene.Lokhu kufezwa iluphu yokulawula impendulo ehlala iqapha futhi ilungisa umjikelezo womsebenzi wesekethe yokushintsha.Umphumela uba ukuthi i-voltage ephumayo ihlala ingashintshile njengoba i-voltage yokufaka noma isidingo somthwalo sishintsha, kuqinisekisa ukusebenza okuhle nokwethembeka ngaso sonke isikhathi.
Ngaphezu kwezinzuzo zobuchwepheshe, izilawuli zokushintsha ze-DC DC kulula ukuzihlanganisa futhi zivumelana nezimo ekwakhiweni.Atholakala ngezindlela ezahlukahlukene zamafomu kanye nezinketho zokupakisha, eziwavumela ukuthi alingane ngaphandle komthungo ezinhlobonhlobo zemiklamo ye-elekthronikhi.Ukwengeza, usayizi wabo ohlangene nesisindo esilula kubenza balungele izinhlelo zokusebenza eziphathwayo nezinesikhala lapho imilimitha ngayinye ibala khona.
Sengiphetha, izilawuli zokushintshwa kwe-DC DC ziguqule umkhakha wobuchwepheshe bokuguqulwa kwamandla, zihlinzeka ngokusebenza kahle nokwethenjelwa komthetho kagesi wemishini yesimanje kagesi.Ngokusebenza kahle kwabo okuhle kakhulu, ububanzi bamandla kagesi okufakwayo, ukulawulwa okunembile kwamandla kagesi kanye nokuvumelana nezimo, sebephenduke isixazululo konjiniyela nabaklami abafuna ukuthuthukisa ukuguqulwa kwamandla emikhiqizo yabo.Njengoba ukuthuthuka kobuchwepheshe kanye nezimfuno zamandla ziqhubeka nokukhula, izilawuli zokushintsha ze-DC DC ngokungangabazeki zizodlala indima ebalulekile ekulolongeni ikusasa lezinhlelo zikagesi nezamandla.
