Ukushintsha ama Amandla Supply - welungelo onokwethenjelwa zobuchwepheshe

Cishe noma yimuphi zikagesi kudinga ukusetshenziswa segezi. Iqiniso lokuthi voltage supply ngokuvamile kakhulu akufani yini edingekayo amadivayisi kakhulu, kulapho badinga ukuqinisekisa ukuqhubeka futhi ungaphazanyiswa ugesi. Incane kakhulu noma high voltage kuzuba ngokushesha okukhipha kunethiwekhi kusukela kunoma yikuphi ukwehluleka imishini. Isixazululo sale nkinga, itholwe isikhathi eside - ukusebenzisa amandla supply olulawula voltage ivikela idivayisi.

Namuhla ukusetshenziswa lwento kanye ukushintsha ukuphakelwa kukagesi. Okokuqala Ngithole ukusabalala ngenxa bemsulwa, impendulo esheshayo kunoma ushintsho umthwalo nokuzinza. Kodwa zikhona nemiphumela ethile engathandeki: kahle ongaphakeme, bulkiness we transformer, nokuzwela voltage input bese ukushabalalisa ukushisa. Ngenxa yalezi zizathu, komugqa segezi kancane esikhundleni wuhlelo ishayela, okuyinto abe ukusebenza okungcono elithe.

Esikhathini sethu, kukhona miniaturization we-apharathasi, ngakho amandla transformer supply wesifunda ingahle yisikhathi. Ukushintsha ama ugesi has lenqwaba izinzuzo, phakathi okuyinto ivelele emazombezombe ukonga impahla, futhi lokhu kuncipha izindleko zedivayisi ngokwayo, Ubukhulu wekugcina, ukuthembeka, ububanzi yokusebenza ububanzi. Lezi zimfanelo ngeke zinganakwa ngomsakazo nayizimfundamakhwela kanye ochwepheshe. Nokho, kukhona ethile: ngisho elula inkinobho imodi ugesi ine uhlelo sendlu ukuze babuthane bese usethe, kodwa leli qiniso akagcini amakhosi zangempela.

UPS yize eqolo ngaphezu kwanoma amabhlogo ezivamile, kodwa hhayi kuphela etholwe futhi zinamandla Lidlulisela ukuthengisela, kodwa uhlaliseke ngokuvikela uqobo futhi izigaba enkingeni. Manje asetshenziswa kabanzi ukushintsha ukuphakelwa kukagesi yomsindo imvamisa amplifier, amadivayisi microcontroller-based, ezishintshayo kusho omunye apharathasi ahlukahlukene. Babeqale elisetshenziswa amathelevishini nama ahlukahlukene okokusebenza kwevidiyo.

Ukushintsha ama ugesi isungule kakade ngokwaso njengoba idivayisi ukonga, onokwethenjelwa futhi kulula ukuyisebenzisa. Manje abakhiqizi bekwi ukuguqulwa onobuhle ekhona ngokuya miniaturization base isici, futhi uthuthukise ukuthembeka kudivayisi.

Ziningi-UPS izikimu, kodwa ukusebenza cishe ku isimiso esifanayo. Single shot generator feeds kakade kuyalungiswa amapayipi voltage, a transformer ishayela umthwalo yesibili kuyinto rectifier, futhi ukusuka lapho bondliwa abathengi. Kuye imodeli, generator kungenzeka yangaphandle noma self-isiqalo. Transistor generator usebenza mode usuke. Uma ivaliwe, konke amandla okungena umthwalo, futhi uma ivulwa - kokushaya transformer amandla agcinwe.

Ukushintsha ama ugesi kuzole futhi oguqula amandla kagesi kusukela kunethiwekhi AC ukuze amandla awadingayo amandla imishini ehlukahlukene. Operating voltage AC, okuyinto asifanele kumadivayisi amaningi futhi ukunciphisa ukusetshenziswa kwabo isikhathi. Amandla Iyunithi enikeza ivikela imishini, wedlula voltage zamukelwa kuphela ngaphandle kokuya ngalé kwemingcele.
