Ngokuthandwa kwezixhobo zombane, umbane wokutshintsha usetyenziswa kakhulu kubomi bethu bemihla ngemihla, kwaye yindlela eyimfuneko yokubonelela ngombane.Emva koko umhleli uyakwazisa unikezelo lwamandla okutshintsha kunye nemimandla yesicelo sakho kuwe.
Ngophuhliso olukhawulezayo lwetekhnoloji ye-elektroniki yamandla, ubudlelwane phakathi kwezixhobo ze-elektroniki zamandla kunye nomsebenzi wabantu kunye nobomi buye basondela ngakumbi, kwaye izixhobo ze-elektroniki azinakwahlulwa kumbane othembekileyo.Ngeminyaka yoo-1980, izixhobo zombane zekhompyuter zaqonda ngokupheleleyo ukutshintshwa kombane, kwaye zakhokela ekugqibezeleni uphuhliso lweekhompyuter.Ukutshintsha izixhobo zombane kungene kwiinkalo ezahlukeneyo zezixhobo zombane kunye nezombane ngeminyaka yoo-1990.Ukutshintsha izixhobo zombane kusetyenziswe ngokubanzi kwiiswitshi ezilawulwa yinkqubo, unxibelelwano, izixhobo zovavanyo zombane, kunye nolawulo lombane, oluye lwakhuthaza uphuhliso olukhawulezayo lokutshintsha iteknoloji yonikezelo lwamandla..Ukutshintsha unikezelo lombane lubonelelo lwamandla ombane olusebenzisa ubuchwephesha banamhlanje bamandla ombane ukulawula umlinganiselo wexesha lokutshintsha nokucima iitransistor ukugcina amandla ombane aphumayo azinzileyo.Ukuhanjiswa kwamandla ombane adityaniswe ngokubanzi ngokumodareyitha kobubanzi be-pulse (PWM) ii-ICs kunye nee-MOSFETs.Xa kuthelekiswa nonikezelo lwamandla ombane, iindleko zokutshintshela umbane zinyuka ngokunyuka kwamandla aphumayo, kodwa izinga lokukhula kwezi zibini lihlukile.Ixabiso lonikezelo lwamandla ombane liphezulu kunokutshintsha kombane kwindawo ethile yokuphuma kwamandla, okuyixabiso lokubuyisela umva.Ngophuhliso kunye nokuveliswa kobuchwephesha bombane we-elektroniki, ukutshintshela itekhnoloji yonikezelo lwamandla rhoqo, kwaye le ndawo yokubuyisela ixabiso iyanda ukuya kwisiphelo sombane esisezantsi, esibonelela ngoluhlu olubanzi lwendawo yophuhliso lokutshintsha unikezelo lwamandla.
Ukunikezelwa kwamandla okutshintsha kukusebenzisa izixhobo zombane zokutshintsha ezifana ne-transistors, i-transistors ye-field effect, i-thyristors, njl., ngokusebenzisa isiphaluka solawulo, ukwenza izixhobo zokuguqula i-elektroniki "zivule" kwaye "zicime" ngokuqhubekayo, ukwenzela ukuba izixhobo zokuguqula i-elektroniki zikwazi. phendula kwi-voltage yegalelo.Yenza uhlengahlengiso lwe-pulse ukuze uqonde uguqulo lombane lwe-DC/AC kunye ne-DC/DC, kunye nombane ohlengahlengiswayo ophumayo kunye nokuzinzisa umbane ozenzekelayo.Ukuhanjiswa kwamandla ombane adityaniswe ngokubanzi ngokumodareyitha kobubanzi be-pulse (PWM) ii-ICs kunye nee-MOSFETs.Ngophuhliso kunye nokuveliswa kweteknoloji yamandla e-elektroniki, umbane otshintshileyo ngoku usetyenziswa ngokubanzi phantse kuzo zonke izixhobo zombane ngenxa yobukhulu obuncinci, ubunzima bokukhanya kunye nokusebenza okuphezulu, kwaye ukubaluleka kwayo kuyabonakala.
Ukunikezelwa kwamandla okutshintshela okuphakamileyo okusemgangathweni yindlela yokuphuhliswa kwayo.I-High-frequency yenza ukunikezelwa kwamandla okutshintsha kuncinci kwaye kwenza ukuba unikezelo lwamandla lokutshintsha lufake uluhlu olubanzi lwezicelo, ngokukodwa kwintsimi ye-high-tech, ekhuthaza ukuchithwa kwe-miniaturization kunye nokukhanya kweemveliso eziphezulu.utshintsho.Ukongeza, uphuhliso kunye nokusetyenziswa kokutshintsha kombane kubaluleke kakhulu ekongeni umbane, ukonga izixhobo kunye nokukhusela okusingqongileyo.
Ukutshintsha kwabantu itekhnoloji yonikezelo lwamandla iphuhlisa izixhobo zombane zombane ezinxulumeneyo ngelixa kuphuhliswa itekhnoloji yokuguqula amaza.Ukukhuthazwa okufanayo kwezi zibini kukhuthaza ukunikezelwa kwamandla okutshintsha ukukhanya, amancinci, amancinci, aphantsi, ukuthembeka okuphezulu, kunye nezinga lokukhula kwamadijithi angaphezu kwamabini ngonyaka.Isikhokelo sophuhliso oluchasene nokuphazamiseka.Ukutshintsha unikezelo lwamandla lunokwahlulwa lube ngamacandelo amabini: AC/DC kunye neDC/DC.Abaguquleli be-DC/DC baye bahlengahlengiswa, kwaye iteknoloji yoyilo kunye nenkqubo yokuvelisa ikhulile kwaye isemgangathweni ekhaya nakwamanye amazwe, kwaye yaqatshelwa ngabasebenzisi, kodwa i-modularization ye-AC / DC, ngenxa yeempawu zayo, yenza ukuba idibane ngakumbi. Iingxaki ezinzima zobugcisa kunye nenkqubo yokwenziwa kwenkqubo kwinkqubo yokumodareyitha.Ubume kunye neempawu zeentlobo ezimbini zokutshintshwa kwamandla ombane zichazwe ngezantsi.
Ukutshintsha izixhobo zombane zisetyenziswa ngokubanzi kulawulo oluzenzekelayo kwimizi-mveliso, izixhobo zomkhosi, izixhobo zophando lwezenzululwazi, izibane ze-LED, izixhobo zolawulo lwamashishini, izixhobo zonxibelelwano, izixhobo zombane, izixhobo zonyango, ifriji yesemiconductor kunye nokufudumeza, izicoci zomoya, iifriji zombane, imiboniso yekristale yolwelo. , Izibane ze-LED , Izixhobo zoNxibelelwano, iimveliso ze-audio-visual, ukubeka esweni ukhuseleko, iingxowa zokukhanya ze-LED, iimeko zekhompyutha, iimveliso zedijithali kunye nezixhobo kunye nezinye iinkalo.
