Ukutshintsha uNikezo lwaMandlaIchaziwe: Iingenelo kunye nezicelo
Ukutshintsha izixhobo zombane, okwaziwa ngokuba yi-switch modeizixhobo zombane (i-SMPS), zithandwa kakhulu kumashishini ahlukeneyo ngenxa yokusebenza kakuhle kunye nokuguquguquka kwazo. Ngenxa yokukwazi kwazo ukuguqula amandla ngempumelelo ukusuka kwenye indlela ukuya kwenye,umbane otshintshayoziye zaba sisisombululo esikhethwayo kwiintlobo ngeentlobo zezicelo ukusuka kwizixhobo ze-elektroniki zabathengi ukuya kwizixhobo zoshishino.
Kwizixhobo zombane zemveli ezithe ngqo, amandla alawulwa ngokukhupha amandla agqithisileyo ngendlela yobushushu, nto leyo ebangela ukusebenza okuphantsi. Nangona kunjalo,umbane otshintshayobaye baguqula ishishini ngokuhlanganisa ii-transistors zamandla ezinokutshintshwa ngokufanelekileyo phakathi kweemeko zokuvula nokuvala, nto leyo enciphisa ukulahleka kwamandla. Olu tshintsho lunyusa ukusebenza kakuhle kwaye lunciphisa ukuveliswa kobushushu, nto leyo eyenza ukuba ilungele ukusetyenziswa kwezicelo ezininzi.
Enye yezona nzuzo ziphambili zeumbane otshintshayoubukhulu bazo buncinci. Ukunciphisa ukulahleka kwamandla kuvumela ukusetyenziswa kwezinto ezincinci, okwenza ukuba zilungele usetyenziso olunesithuba esincinci njengezixhobo eziphathwayo. Ukongeza, xa kuthelekiswa nezixhobo zamandla ezithe ngqo, izixhobo zamandla ezitshintshayo zilula ngobunzima, zongeza ukuphatheka kwazo kunye nokulula kokusetyenziswa.
Ukutshintsha izixhobo zombaneKwakhona kubonelela ngoluhlu olubanzi lwe-voltage yokufaka, nto leyo eyenza ukuba zihambelane nemithombo eyahlukeneyo yamandla kwimimandla eyahlukeneyo. Olu tshintsho luqinisekisa ukuba izixhobo ze-elektroniki zinokusebenza kwihlabathi liphela ngaphandle kwesidingo see-adaptha ezongezelelweyo okanye utshintsho. Ukongeza, izixhobo zamandla ezitshintshayo zinokuphatha uluhlu olubanzi lwe-voltage yokuphuma, nto leyo evumela ukuba zinike amandla izixhobo ezahlukeneyo ezineemfuno ezahlukeneyo ze-voltage.
Ngokuphathelele ukuthembeka,umbane otshintshayozineengenelo ngaphezu kwezixhobo zamandla ezithe ngqo. Uyilo lwazo oluqinileyo lususa isidingo sezinto ezinkulu nezinokungaphumeleli ezifana neetransformers kunye nee-capacitors. Oku ekugqibeleni kwandisa ubomi benkonzo kwaye kuphucula ukuthembeka kwenkqubo iyonke.
Ukuguquguquka kweumbane otshintshayozifikelela kuluhlu olubanzi lwezicelo zazo. Ukususela ekunikezeni amandla kwi-elektroniki yabathengi njengee-smartphones, iilaptops, kunye nee-consoles zemidlalo, ukuya kwizicelo ezininzi zoshishino ezifana nonxibelelwano, i-aerospace, kunye nezixhobo zonyango, azinakuthelekiswa nazo ngokuziqhelanisa. Ukongeza, izixhobo zamandla ezitshintshayo zisetyenziswa rhoqo kwiinkqubo zamandla ahlaziyekayo ezifana neephaneli zelanga kunye nee-wind turbines ngenxa yokuguqulwa kwamandla aphezulu kunye nokusebenza kakuhle kolawulo.
Nangonaumbane otshintshayoZineengenelo ezininzi, zikwanazo nemida ethile. Umzekelo, zinokungenisa ukuphazamiseka kwe-electromagnetic (EMI) ngenxa yokusebenza kokutshintsha rhoqo. Ukunciphisa le ngxaki, kusetyenziswa izixhobo zokucoca ezongezelelweyo. Ukongeza, ukuyila nokuvelisa izixhobo zombane zokutshintsha kufuna ulwazi olukhethekileyo kunye nobuchule ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokhuseleko.
Ukuququmbela,umbane otshintshayoziye zaguqula ishishini lombane ngokusebenza kakuhle, ubungakanani obuncinci, kunye nokuguquguquka. Ukukwazi ukuguqula amandla ngokufanelekileyo kunye nobubanzi bevolthi yokufaka kunye neyokukhupha kubenza babe lukhetho lokuqala kwiintlobo ngeentlobo zezicelo. Njengoko itekhnoloji iqhubeka ihambela phambili,umbane otshintshayongokungathandabuzekiyo kuya kudlala indima ebalulekileyo ekunikeni amandla izixhobo neenkqubo zexesha elizayo.
