Njengoba ubuchwepheshe buthuthuka, isidingo semishini kagesi siyaqhubeka sikhula. Ekuhlangabezaneni nalezi zidingo, amandla kagesi e-DC ashintsha imvamisa ephezulu abe ubuchwepheshe obubalulekile. Kusukela kumishini yezokuxhumana kuye kumishini yezokwelapha, kusukela kuzilawuli zezimboni kuya kugesi womuntu siqu,high frequency switching DC amandla kagesizingene kuzo zonke izici zokuphila kwethu. Ngakho-ke, yini ngempela i-high frequency switching DC power supply, futhi isebenza kanjani?
Okokuqala, masiqonde izimiso zayo eziyisisekelo. Ukunikezwa kwamandla kwe-DC okushintsha imvamisa ephezulu kuwuhlelo lwamandla olungaguqula amandla okufaka ashintshayo wamanje (AC) abe okukhipha amandla kagesi amanje aqondile (DC) aqinile. Uma kuqhathaniswa nabalawuli bomugqa bendabuko,imvamisa ephezulu yokushintsha amandla kagesi we-DCzinikeza ukusebenza kahle okuphezulu nosayizi omncane, okwenza zisetshenziswe kabanzi kumishini ehlukahlukene ye-elekthronikhi.
Ukusebenza kweimvamisa ephezulu yokushintsha amandla kagesi we-DCngokuyinhloko isekelwe ezingxenyeni ezimbili ezibalulekile: isilawuli esishintshayo kanye nesifunda sokulawula. Isilawuli esishintshayo silawula i-voltage ephumayo yomthombo wamandla sisebenzisa amadivaysi okushintsha ama-high-frequency (njengama-MOSFET), kuyilapho isifunda sokulawula siqapha i-voltage ephumayo futhi silungisa isilawuli sokushintsha ukuze sigcine i-voltage ephumayo ezinzile.
Kule nqubo, amandla e-AC okokufaka aqale alungiswe abe amandla e-DC ngesilungisi, bese alawulwa isilawuli esishintshayo, futhi azinziswe ngesekhethi yokulawula. Le nqubo esebenza kahle yokuguqula amandla inika amandlaimvamisa ephezulu yokushintsha amandla kagesi we-DCukunganikezi kuphela amandla okukhipha amandla azinzile kodwa futhi uzuze ukuguqulwa kwamandla asebenza kahle kakhulu ngaphansi kwezimo ezihlukene zomthwalo.
Izicelo zeimvamisa ephezulu yokushintsha amandla kagesi we-DCzihlukahlukene kakhulu. Emkhakheni wemishini yezokuxhumana, banganikeza amandla azinzile futhi athembekile ukuze kuqinisekiswe ukusebenza okuvamile kwamadivayisi okuxhumana. Emishinini yekhompuyutha, banganikeza ukusekela kwamandla okuzinzile ezingxenyeni ezifana nama-CPU namakhadi ezithombe. Emkhakheni wemishini yezokwelapha, bangahlinzeka ngokukhipha amandla okunembile kwemishini yezokwelapha ukuze kuqinisekiswe ukusebenza kahle kokwelashwa.
Ngokufigqiwe,imvamisa ephezulu yokushintsha amandla kagesi we-DCzisebenza kahle, zizinzile, futhi zithembekile ubuchwepheshe bokuguqula amandla osebuyingxenye ebalulekile yezinto zesimanje zikagesi. Ngokuthuthuka kobuchwepheshe obuqhubekayo, kukholakala ukuthi ugesi we-DC oshintshashintsha kakhulu uzodlala indima ebaluleke nakakhulu esikhathini esizayo, ulethe ukunethezeka okukhulu kanye namathuba ezimpilweni zethu.
