Izinto ezintsha kunye nezakuqala ze-elektroniki, ii-ICs zoLawulo lwaMandla ashushu HTSSOP-14 LM5010 LM5010MHX/NOPB

inkcazelo emfutshane:

Umlawuli we-LM5010 we-step-down switching regulator ubonisa yonke imisebenzi efunekayo ukuze kuphunyezwe umlawuli we-buck bias ophantsi kwexabiso eliphantsi, elisebenzayo, elikwazi ukubonelela ngaphezu kwe-1-A yangoku yomthwalo.Lo mlawuli we-voltage ephezulu uqulethe i-N-Channel Buck Switch, kwaye ifumaneka kwi-thermal ephuculweyo ye-10-pin ye-WSON kunye ne-14-pin ye-HTSSOP iiphakheji.Iskimu solawulo lwe-hysteretic asifuni mbuyekezo ye-loop, ekhokelela ekuphenduleni komthwalo okhawulezayo, kunye nokwenza lula ukuphunyezwa kwesekethe.I-frequency yokusebenza ihlala ihleli kunye nomgca kunye nokuhluka komthwalo ngenxa yobudlelwane obuphambeneyo phakathi kwe-voltage input kunye ne-ON-time.Ukubona umda wangoku kwintlambo ibekwe kwi-1.25 A. Iimpawu ezongezelelweyo zibandakanya: i-VCC undervoltage lockout, ukuvalwa kwe-thermal, i-gate drive undervoltage lockout, kunye ne-miniter duty cycle limiter.

Umsebenzi ongundoqo

Umsebenzi oyintloko we-voltage regulator.
1. Ukuzinziswa kwamandla ombane.
Xa i-voltage yegridi iguquguquka ngokukhawuleza, umlawuli we-voltage uya kuhlawulela i-voltage amplitude ngesantya sokuphendula se-10-30ms, esenza ukuba izinzile ngaphakathi kwe-± 2%.
2. ukhuseleko oludibeneyo olunemisebenzi emininzi.
Isilawuli samandla ombane ukongeza kowona uzinzo olusisiseko lomsebenzi wombane kufuneka kwakhona sibe nokhuseleko lokugqithiswa kwamandla ombane (ngaphezulu kwe-+10% yombane ophumayo), ukhuseleko olungaphantsi kwe-voltage (ngaphantsi kwe-10% yombane ophumayo), ukhuseleko lwesigaba sokungaphumeleli. , ukukhuselwa komthwalo omfutshane wesekethe eyona misebenzi yokhuseleko olusisiseko.
3. Uxinzelelo lwe-spike pulse (ukhetho).
Igridi yamandla ngamanye amaxesha ine-amplitude ephezulu kakhulu, ububanzi be-pulse yi-spike pulse emxinwa kakhulu, kwaye iya kugqobhoza kumbane osezantsi ukumelana nezinto ze-elektroniki.Amacandelo achasene nokunyuka kwamandla ombane alawulwayo angadlala indima entle kakhulu ekucinezeleni iipulse ezibukhali ngolo hlobo.
4. Ukwahlukaniswa kokuphazamiseka kwe-EMI electromagnetic conductive (ukhetho).
CNC izixhobo ngaphezulu AC/DC rectifier + PFC high-frequency amandla factor correction, ngokwayo isixa esithile sokuphazamiseka ngaxeshanye umthombo wophazamiseko uneemfuno ezingqongqo.Amacandelo okucoca unikezelo lwamandla alawulwayo anokwahlula ngokufanelekileyo uphazamiseko lwegridi kwisixhobo kwangaxeshanye anokwahlula ngokufanelekileyo uphazamiseko lwesixhobo kwigridi.
5. ukukhuselwa kombane (ukhetho).
Kufuneka ube namandla okukhusela ekubetheni kombane.

Iindidi

I-DC voltage regulator inokwahlulwa ibe ngamacandelo amabini.

1, uhlobo lokutshintsha
Uhlobo olwahlukileyo lonikezelo lwamandla oluzinzileyo oluvela kumbane olawulwa ngumgca luhlobo lokutshintshela umbane olawulwayo we-DC, onohlobo lwesekethe ye-flyback enesiphelo esisodwa, i-single-ended forward, i-half-bridge, push-pull and full-bridge.Umahluko osisiseko phakathi koku kunye nonikezelo lwamandla ombane kukuba isiguquli asisebenzi kumaza okusebenza kodwa amashumi ekilohertz ukuya kwiimegahertz ezininzi.Umbhobho wokusebenza awusebenzi kwindawo yokuzalisa kunye neyokunqunyulwa kwemeko yokutshintsha;ukutshintsha unikezelo lwamandla oluthiywe ngolo hlobo.

2,Umgca
Isilawuli sombane somgca sinento eqhelekileyo ekubeni ityhubhu yesilawuli sesixhobo samandla sisebenza kwindawo yomgca, sixhomekeke ekuhlalweni kombane phakathi kombhobho wokulawula ukuzinzisa imveliso.Ngenxa yelahleko enkulu ye-static yombhobho wokulawula, isitya esikhulu sokushisa kufuneka sifakwe ukukhupha ubushushu kuyo.I-transformer nayo inzima kuba isebenza kwi-50Hz.

Iingenelo zolu hlobo lonikezelo lwamandla luzinzo oluphezulu, i-ripple encinci, ukuthembeka okuphezulu, kulula ukwenza ezininzi, ukukhutshwa ngokuqhubekayo kokulungiswa kwemveliso egqityiweyo.Izinto ezingeloncedo kukuba zikhulu, zininzi, kwaye zingasebenzi kakuhle.Olu hlobo lonikezelo lwamandla oluzinzileyo kwaye kukho iintlobo ezininzi, ukusuka kubume bemveliso inokwahlulwa ibe yi-voltage ezinzile unikezelo lwamandla kunye nonikezelo lwangoku oluzinzileyo lombane kunye neseti yokuqina kwamandla ombane, uzinzo lwangoku kwi-voltage ezinzileyo, kunye neyangoku (ezimbini-ezizinzileyo. ) ukunikezwa Amandla.Ixabiso lemveliso linokwahlulwa libe yi-fixed-point output power supply, i-band switch-adjustable, kunye ne-potentiometer ngokuqhubekayo uhlobo oluhlengahlengiswayo oluninzi.Ukusuka kwimveliso, isalathiso sinokwahlulwa sibe luhlobo lwesalathisi kunye nohlobo lokubonisa idijithali, njalo njalo. 三、

Yazisa

Ukunikezelwa kwamandla okutshintsha kwe-DC.
Iingenelo zokutshintsha izixhobo zombane bubukhulu babo obuncinci, ubunzima, ukuzinza, kunye nokuthembeka.Zifumaneka kuluhlu lwamandla ukusuka kwiiwatts ezimbalwa ukuya kwiikilowathi ezininzi.Nazi izinto ezimbalwa zokutshintsha amandla
1. Izibonelelo zombane zonxibelelwano
Ubonelelo lwamandla onxibelelwano luluhlobo lombane loguqulelo lwe-DC/DC, kodwa ngokuqhelekileyo lubonelelo lwamandla lwe-DC-48V okanye -24V, kunye nebhetri egciniweyo yobonelelo lwamandla e-DC, umbane wobonelelo lwe-DC kumbane womsebenzi wesekethe, uqhelekile. yahlulwe kunikezelo lwamandla elisembindini, unikezelo lwamandla olunamaleko, kunye nonikezelo lombane lwebhodi enye ezintathu, le yokugqibela yeyona ithembekileyo.
2. AC / DC
Olu hlobo lonikezelo lwamandla, olukwabizwa ngokuba lubonelelo lwamandla oluphambili, lufumana amandla kwigridi yamandla kwaye lufumana amandla ombane aphezulu eDC ngokulungiswa kwamandla ombane aphezulu kunye nokuhluza isiguquli seDC/DC ukufumana enye okanye ezininzi ezizinzileyo zombane zeDC kwimveliso, amandla ukusuka kwiiwatts ezimbalwa ukuya kwikilowatts ezininzi.Kukho uluhlu olubanzi lweenkcukacha zeemveliso ezinjalo, kunye nonikezelo lwamandla oluphambili (igalelo le-AC220, i-DC48V, okanye i-24V yemveliso) kunikezelo lwamandla onxibelelwano luloluhlobo, ngokuxhomekeke kwiimfuno zomsebenzisi.
3. Ubonelelo lwamandla emodyuli
Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe, ukuthembeka konikezelo lwamandla, kunye nomthamo / umthamo womthamo uyanda, unikezelo lwamandla lwemodyuli luya lubonisa ukongama kwalo, lusebenza kwi-frequency ephezulu, ubungakanani obuncinci, ukuthembeka okuphezulu, ukufakwa lula. kunye nendibaniselwano yokwandiswa, ngoko ngakumbi nangakumbi kusetyenziswa ngokubanzi.Nangona kukho imveliso yemodyuli yasekhaya ehambelanayo, ngenxa yokuba inkqubo yokuvelisa ayizange ibanjwe kwinqanaba lamazwe ngamazwe, izinga lokungaphumeleli liphezulu.
4. Ubonelelo lwamandla kanomathotholo
Igalelo lombane werediyo i-AC220V/110V, imveliso ye-DC13.8V, amandla ngamandla esikhululo sikanomathotholo, ii-amps ezimbalwa, kunye namakhulu ee-amps akhoyo.Ukuthintela ukusilela kombane wegridi ye-AC ukuchaphazela umsebenzi kanomathotholo, kwaye kufuneka ube nepakethi yebhetri njengogcino, ke olu hlobo lonikezelo lwamandla ukongeza kwimveliso yombane we-13.8V DC lukwanalo nebhetri etshaja umsebenzi woguqulo oluzenzekelayo.
5. DC/DC
Kwinkqubo yonxibelelwano, ekwabizwa ngokuba lunikezelo lombane lwesibini, lunikezelo lwamandla oluphambili okanye ipakethe yebhetri yeDC ukubonelela ngegalelo lombane weDC, emva kokuguqulwa kweDC/DC kwicala lemveliso ukuze kufumaneke umbane weDC okanye iivolthi ezininzi zeDC.
Nangona unikezelo lwamandla kwimodyuli yeDC/DC lubiza kakhulu, ukusuka kwindawo yokujonga ixabiso elipheleleyo lomjikelo wesicelo omde wemveliso, ngakumbi ngenxa yokungaphumeleli kwenkqubo kunye neendleko eziphezulu zokugcinwa kunye nokulahleka kobubele, ukhetho lwemodyuli yamandla. iseyindleko esebenzayo, kuyafaneleka ukukhankanya apha i-Roche converter circuit, inzuzo yayo ebalaseleyo yisakhiwo esilula sesekethe, ukusebenza okuphezulu kunye nombane ophumayo kunye nexabiso le-ripple langoku elikufutshane ne-zero.
6. Izibonelelo zamandla ezikhethekileyo
Amandla ombane aphezulu kunye nombane ophantsi wangoku, izixhobo zombane eziphezulu zangoku, i-400Hz igalelo lombane we-AC/DC, njl njl.
