Isimame wamanje: isiqu, incazelo isikimu

Umuntu namuhla njalo lizungezwe lenqwaba zikagesi, kokubili ekhaya nasezimbonini. Kunzima ukucabanga ngokuphila kwethu ngaphandle amadivaysi kagesi, base wangena ngesinyenyela endlini. Ngisho sinemali uyohlale khona kumadivayisi ambalwa ezinjalo. Konke lokhu ubuchwepheshe for ukusebenza kwawo esitebeleni kudinga ukulokhu ugesi. Ngemva engahlelekile the amapayipi voltage zamanje avame imbangela yokwehluleka zedivayisi.

Ukuqinisekisa izinga ukunikezela imishini yezobuchwepheshe okungcono kakhulu esinakho iwukusebenzisa isimame zamanje. Uyokwazi isinxephezelo iyehla iyenyuka inethiwekhi futhi baphile isikhathi eside service.

isimame wamanje - idivayisi okuyinto igcina ngokuzenzakalela wamanje umthengi nge ngokunemba kusengaphambili. Ihlawula imvamisa we yokwanda kwama samanje inethiwekhi, ushintsho kwamandla umthwalo kanye lokushisa kuma. Ngokwesibonelo, okwandisa amandla sokudliwa idivayisi, izoshintsha wamanje okokufaka, okubangela voltage iconsi ngesikhathi ukumelana omthombo wiring ukumelana. Kukhula ukubaluleka ukumelana kwangaphakathi, voltage ngaphezulu zizoshintsha nge okwandisa umthwalo lamanje.

Isinxephezelo isimame lwamanje idivayisi ukuzilawula ngokuzenzekelayo, okuyindawo ehlanganisa uchungechunge impendulo engeyinhle. Ukuqina kufezwa ngokushintsha kwemigomo ilungu ukulungisa, esimweni ukuchayeka ishayela impendulo. Lokhu ipharamitha ibizwa ngokuthi umsebenzi wamanje okukhiphayo. Regulatory kusho compensatory stabilizers zamanje yilezi: okuqhubekayo, pulsed futhi edidayo.

Amapharamitha main:

1. Baqine isici ukubaluleka voltage okokufaka:

_St.t K = (ΔU _Rin / ΔI _H) * (mina _H / U _Bx), lapho

Mina _n, ΔI _n - Inani lamanje futhi ukubaluleka anyuswe we samanje umthwalo.

_St.t Coefficient K ebalelwa njalo umthwalo ukumelana.

2. Coefficient sinjalo uma ukumelana noshintsho:

K _{R H} = (ΔR _n / R _n) * (mina _H / ΔI _H ) = R _i / R _{H, lapho}

R _H , ΔR _n - kanye anyuswe we ukumelana ukumelana umthwalo;

r _i - ukubaluleka of yangaphakathi ukumelana isimame.

Coefficient K _{R H} ibalwa nge voltage okokufaka njalo.

3. Inani lokushisa Coefficient isimame: γ = ΔI _n / Δt _env.

Ukuze amandla imingcele stabilizers uyalandisa kahle: η = P _O / P _Rin.

Cabangela ezinye izikimu stabilizers.

A kakhulu ziyasatshalalaiswa isimame zamanje FET, lapho esangweni sesiwancamulile nomthombo, ngokulandelana, U = 0 _izibopho. I Transistor esifundeni ezifana ixhumeke uchungechunge ekumelaneni umthwalo. Amaphuzu ezimpambanweni zomgwaqo iqondile umthwalo okukhipha sici Transistor ukucacisa Inani lamanje ngesikhathi encane kunazo zonke futhi ukubaluleka elikhulu voltage input. Nge umthwalo ongako wesifunda yamanje kuyahlukahluka kancane nge ukushintshashintsha okuphawulekayo voltage input.

Ukushintsha ama Regulator litshwayo yalo iyona samanje Transistor - isilawuli esimweni usuke. Lokhu kwenza kube nokwenzeka ukuba ukwandisa nekusebenta idivayisi. Pulsed isimame lwamanje uhlobo Converter olulodwa ephelile imbozwe negative impendulo iluphu. Amadivayisi anjalo kuncike ukuqaliswa amandla iyunithi zingahlukaniswa zibe izinhlobo ezimbili: a uchungechunge uxhumano a mpintsha kanye Transistor; ne ukuxhumana serial kanye parallel inductor Regulator Transistor uxhumano.
