Ukutshintshela Power Supply - okhuselayo ethembekileyo bezixhobo zombane

Phantse zonke izixhobo ze-elektroniki ifuna ukusetyenziswa zokuxhasa ngamandla. Isibakala sokuba ombane unikezelo kuvamile akufani noko eziyimfuneko izixhobo ezininzi, kokukhona kufuneka ukuqinisekisa okuqhubayo kunye ungaphazanyiswa supply namandla. ombane aphantsi kakhulu okanye phezulu utsiba ngokukhawuleza imveliso kwinethiwekhi nakweyiphi ukusilela izixhobo. Isisombululo sale ngxaki kwafunyanwa ixesha elide - kukuba ukusebenzisa unikezelo amandla olawula ombane kwaye ikhusela ifowuni.

Namhlanje ukusetyenziswa kumgama owazisayo kunye unikezelo lwamandla kokusebenzisa. Kuqala ndafumana ukusasazeka ngenxa eyeke umzimba, ukusabela ngokukhawuleza naluphi na utshintsho umthwalo kunye nozinzo. Kodwa kukho ethile: ukusebenza phantsi, bulkiness le transformer, lo kuvelana ombane igalelo ukusasaza ubushushu. Ngenxa yezi zizathu, unikezelo lombane yomgama ngokucotha zithathelwa indawo ukubetha, leyo ikwazi ukusebenza ethe ngcono.

Ekuhambeni kwexesha lethu, kukho miniaturization le apparatus, ngoko unikezelo sombane amandla yesekethe sele kuphelelwa. Ukutshintshela umbane kukho inani elikhulu yeenzuzo, simi phakathi apho phandle imali eziphathekayo jiko, yaye oku ukwehliswa kwamaxabiso isixhobo ngokwalo, imilinganiselo zicocekile, ukuthembeka, ngokubanzi uluhlu yokusebenza. Ezi mpawu ayikwazi ngoyaba yi amateurs koonomathotholo kunye neengcali. Noko ke, kukho into ethile, nokuba unikezelo lwamandla imo switch esilula icebo sendlu ukuze aqokelele aze kumisa, kodwa loo nto ayithethi ukunqanda iinkosi wokwenene.

UPS nangona ibiza ngaphezu iibhloko eqhelekileyo, kodwa azikho nje ifunyenwe kunye ombane samaza unikezelo, kodwa sazinza ngokukhusela ngokwawo kwaye zikumanqanaba ahlukeneyo lembandezelo. Ngoku ngokubanzi ukuguqukela unikezelo amandla ngombhobho frequency odiyo, izixhobo microcontroller-based, kunye esizisebenzelayo kuthetha ukuba ezinye izixhobo ezahlukeneyo. Ekuqaleni, ukuba zazisetyenziswa iiseti kamabonakude kunye nezixhobo ezahlukeneyo yevidiyo.

Ukutshintshela umbane sele lusekiwe ngokwalo njengoko isixhobo olunoqoqosho, ethembekileyo kwaye kulula ukuyisebenzisa. Ngoku abavelisi benza a loyamano imifuziselo ezikhoyo ngokwemigaqo miniaturization we kwisiseko element, kwaye kuphuculwe ukuthembeka kwefowuni.

Kukho amacebo UPS ezininzi, kodwa zisebenza phantse kumgaqo. Single shot generator feeds sele kuyalungiswa-mbane ombane, transformer ukubetha kunye nomthwalo zamabanga a rectifier, yaye ukusuka apho ifumana ngabathengi. Kuxhomekeka imodeli, umvelisi inokuba zangaphandle okanye self-lokuqala. transistor generator isebenza kwimo utshintshayo. Xa ivaliwe kuyo, zonke ezi amandla iya umthwalo, yaye xa kuvulwa - in ukubetha sombane amandla agciniweyo.

Ukutshintshela umbane omeleza kwaye esiguqula amandla ombane ukusuka kuthungelwano AC ukuya eneji efunekayo ukuze amandla izixhobo ezahlukeneyo. ombane zokusebenza AC, nto leyo ifanele izixhobo ezininzi nokunciphisa ukusetyenziswa kwabo kwexesha. Iyunithi unikezelo lwamandla sikhusela izixhobo, badlula ombane eyamkelekileyo kuphela ngaphandle kokuya ngaphaya kwemida.
