Izingxenye ze-elekthronikhi ezintsha nezangempela, ama-ICs okuphatha amandla ashisayo HTSSOP-14 LM5010 LM5010MHX/NOPB

incazelo emfushane:

Isilawuli sokushintshela phansi se-LM5010 sibonisa yonke imisebenzi edingekayo ukuze kusetshenziswe isilawuli esishibhile esinezindleko eziphansi, esisebenza kahle, esikwazi ukuhlinzeka ngokudlula komthwalo wamanje ongu-1-A.Lesi silawuli se-high-voltage siqukethe I-N-Channel Buck Switch, futhi sitholakala ngamaphakeji we-HTSSOP angu-10-pin athuthukiswe ngokushisa kanye nangama-HTSSOP angu-14.Isikimu sokulawula i-hysteretic asidingi isinxephezelo se-loop, okuholela ekuphenduleni kwesikhashana komthwalo osheshayo, futhi senza ukuqaliswa kokujikeleza kube lula.I-frequency yokusebenza ihlala ihambisana nokuhluka komugqa nomthwalo ngenxa yobudlelwane obuphambene phakathi kwe-voltage yokufaka kanye ne-ON-time.Ukutholwa komkhawulo wamanje esigodini kusethelwe ku-1.25 A. Izici ezengeziwe zifaka: Ukukhiya kwe-VCC undervoltage, ukuvala shaqa kwe-thermal, ukuvala i-gate drive undervoltage lockout, kanye nesikhawuli somjikelezo omkhulu wokusebenza.

Umsebenzi Oyinhloko

Umsebenzi oyinhloko we-voltage regulator.
1. Ukuqina kwamandla kagesi.
Lapho i-voltage yegridi ishintshashintsha ngaso leso sikhathi, isilawuli sikagesi sizonxephezela i-voltage amplitude ngesivinini sokuphendula esingu-10-30ms, siyenze izinze phakathi kuka-±2%.
2. Ukuvikelwa okuhlanganisiwe okunemisebenzi eminingi.
Isilawuli sikagesi ngaphezu kokuqiniswa okuyisisekelo komsebenzi kagesi kufanele futhi sibe nokuvikelwa kwe-voltage ngokweqile (ngaphezu kuka-+10% we-voltage ephumayo), ukuvikelwa ngaphansi kwe-voltage (ngaphansi kuka -10% we-voltage ephumayo), ukuvikela ukwehluleka kwesigaba. , ukuvikelwa kokulayishwa kwesekethe emfushane imisebenzi yokuvikela eyisisekelo kakhulu.
3. Ukucindezela kwe-spike pulse (kuyakhetheka).
Igridi yamandla kwesinye isikhathi iba ne-amplitude ephezulu kakhulu, ububanzi be-pulse iyi-spike pulse emincane kakhulu, futhi izodabula i-voltage ephansi imelane nezingxenye ze-elekthronikhi.Izingxenye ezimelene nokuhlinzwa zokunikezwa kwamandla okulawulwayo zingadlala indima enhle kakhulu ekucindezeleni ama-pulses abukhali kangaka.
4. ukuhlukaniswa kokuphazanyiswa kwe-electromagnetic conductive EMI (kuyakhetheka).
Imishini ye-CNC ngaphezulu kwe-AC/DC rectifier + PFC high-frequency power factor correction, ngokwayo inani elithile lokuphazamiseka ngesikhathi esifanayo umthombo wokuphazamiseka nawo unezidingo eziqinile.Izingxenye zokuhlunga zikagesi ezilawulwayo zingahlukanisa ngokuphumelelayo ukuphazamiseka kwegridi kumishini ngesikhathi esifanayo futhi zingahlukanisa ngokuphumelelayo ukuphazamiseka kwemishini kugridi.
5. ukuvikelwa kombani (ongakukhetha).
Kufanele ibe nekhono lokuvikela umbani.

Izigaba

I-DC voltage regulator ingahlukaniswa izigaba ezimbili.

1, ukushintsha uhlobo
Uhlobo oluhlukile lokunikezwa kwamandla okuzinzile kusukela kugesi olawulwayo olayini wuhlobo lokushintshwa kwamandla kagesi alawulwayo e-DC, enohlobo lwesekethe ye-flyback ene-single-ended, i-single-ended forward, i-half-bridge, push-pull kanye nebhuloho eligcwele.Umehluko obalulekile phakathi kwalokhu kanye nokunikezwa kwamandla kagesi ukuthi i-transformer ayisebenzi kumaza okusebenza kodwa amashumi e-kilohertz kuya kuma-megahertz ambalwa.Ishubhu elisebenzayo alisebenzi endaweni yokugcwala nendawo enqamuliwe okuyisimo sokushintshwa;ukushintsha ukunikezwa kwamandla okuqanjwe kanjalo.

2, Line
Isilawuli sikagesi esingumugqa sinesici esivamile ngokuthi ishubhu yesilawuli sedivayisi yaso samandla sisebenza endaweni yomugqa, sincike ekwehleni kukagesi phakathi kweshubhu lokulawula ukuze kuzinze okukhiphayo.Ngenxa yokulahleka okukhulu okumile kweshubhu lesilawuli, isinki esikhulu sokushisa sidinga ukufakwa ukuze kukhishwe ukushisa kuso.I-transformer nayo isindayo ngoba isebenza ku-50Hz.

Izinzuzo zalolu hlobo lokunikezwa kwamandla ukuzinza okuphezulu, i-ripple encane, ukuthembeka okuphezulu, kulula ukwenza okuningi, ukuphuma okuguquguqukayo okuqhubekayo komkhiqizo oqediwe.Okubi ukuthi makhulu, makhulu, futhi awasebenzi kahle.Lolu hlobo lokunikezwa kwamandla okuzinzile futhi kunezinhlobo eziningi, kusukela esimweni sokuphumayo kungahlukaniswa kugesi ozinzile kanye nogesi ozinzile wamanje kanye nesethi yokuqina kwamandla kagesi, ukuzinza kwamanje ku-voltage ezinzile, kanye nesimanje (i-dual-stable ) ukunikezwa kwamandla kagesi.Inani lokuphumayo lingahlukaniswa libe indawo yamandla ephumayo enamaphuzu angaguquki, ibhande elishintshekayo, kanye ne-potentiometer ehlala ilungiseka ngohlobo oluningana.Kusukela kokuphumayo, inkomba ingahlukaniswa ngohlobo lwenkomba yesikhombi kanye nohlobo lokubonisa lwedijithali, njalonjalo.三、

Ngenisa

Izinsiza zamandla ezishintshayo ze-DC.
Izinzuzo zokushintshwa kwamandla kagesi usayizi wawo omncane, ongasindi, ukuqina, nokuthembeka.Atholakala ezinhlotsheni zamandla ukusuka kuma-watts ambalwa ukuya kuma-kilowatts amaningana.Nazi izinto ezimbalwa zokushintsha amandla
1. Izimpahla zamandla okuxhumana
Ukunikezwa kwamandla okuxhumana empeleni kuwuhlobo lwamandla okuguqula i-DC/DC, kodwa ngokuvamile ugesi we-DC-48V noma -24V, kanye nebhethri eliyisipele likagesi we-DC, i-DC supply voltage ku-voltage yomsebenzi wesekethe, ngokuvamile ihlukaniswe phakathi nendawo yamandla kagesi, ukunikezwa kwamandla okugqinsiwe, kanye nokunikezwa kwamandla ebhodi elilodwa lesithathu, lesi sakamuva sinokwethenjelwa kakhulu.
2. AC/DC
Lolu hlobo lokuphakelwa kukagesi, olukwaziwa nangokuthi ukunikezwa kwamandla okuyinhloko, luthola amandla kugridi yamandla futhi luthola amandla kagesi aphezulu e-DC ngokulungiswa kwamandla kagesi aphezulu kanye nokuhlunga ukuze isiguquli se-DC/DC sithole i-DC/DC ezinzile eyodwa noma amaningana lapho kuphuma khona, amandla asukela kuma-watts ambalwa ukuya kuma-kilowatts amaningana.Kukhona ukucaciswa okubanzi kwemikhiqizo enjalo, kanye nokunikezwa kwamandla okuyisisekelo (okokufaka kwe-AC220, i-DC48V, noma ukuphuma kwe-24V) ekunikezeni amandla okuxhumana nakho kungalolu hlobo, kuye ngezidingo zomsebenzisi.
3. Ukunikezwa kwamandla kwe-modular
Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ukuthembeka kokunikezwa kwamandla, kanye nesilinganiso somthamo / umthamo siya ngokuya siphezulu, ukunikezwa kwamandla emojula kuya ngokuya kukhombisa ukuphakama kwawo, kusebenza ngemvamisa ephezulu, usayizi omncane, ukuthembeka okuphezulu, ukufakwa kalula. kanye nenhlanganisela yokwandisa, ngakho-ke kusetshenziswa kabanzi.Nakuba kukhona ukukhiqizwa kwemojula yasekhaya ehambisanayo, ngenxa yokuthi inqubo yokukhiqiza ayizange ifinyelele ezingeni lamazwe ngamazwe, izinga lokuhluleka liphezulu.
4. Ukunikezwa kwamandla omsakazo
Okokufaka kwamandla omsakazo we-AC220V/110V, okukhipha i-DC13.8V, amandla ngamandla esiteshi somsakazo, ama-amps ambalwa, namakhulu ama-amps ayatholakala.Ukuze uvimbele ukwehluleka kwamandla egridi ye-AC ukuthikameze umsebenzi womsakazo, futhi kudingeka ukuba nephakethe lebhethri njengesipele, ngakho lolu hlobo lokunikezwa kwamandla ngaphezu kokuphuma kwamandla kagesi angu-13.8V DC luphinde lube nomsebenzi wokuguqula okuzenzakalelayo oshaja ibhethri.
5. DC/DC
Ohlelweni lwezokuxhumana, olwaziwa nangokuthi ugesi wesibili, luwumthombo wamandla oyinhloko noma iphakethe lebhethri le-DC ukuze linikeze amandla kagesi okufakwayo e-DC, ngemva kokuguqulwa kwe-DC/DC ohlangothini olukhiphayo ukuze kutholwe amandla kagesi e-DC noma ama-voltage ambalwa e-DC.
Nakuba ukunikezwa kwamandla kwemojula ye-DC/DC kubiza kakhulu, ngokombono wezindleko eziphelele zomjikelezo omude wesicelo somkhiqizo, ikakhulukazi ngenxa yokungaphumeleli kwesistimu nezindleko eziphezulu zokugcinwa nokulahlekelwa kokuthakazelelwa, ukukhethwa kwemojula yamandla. isabiza kakhulu, futhi kufanelekile ukusho lapha i-Roche converter circuit, inzuzo yayo evelele isakhiwo esilula sesekhethi, ukusebenza kahle okuphezulu kanye nokukhishwa kwe-voltage kanye nenani le-ripple lamanje eliseduze no-zero.
6. Izimpahla ezikhethekile zamandla
Amandla kagesi aphezulu namandla aphansi amanje, amandla aphezulu amanje, okokufaka okungu-400Hz kagesi we-AC/DC, njll. kungahlukaniswa njengokunjalo futhi kungakhethwa ngokwezidingo ezikhethekile.
