Intshayelelo yeMveliso
1.I-Voltage uzinzile unikezelo lwamandla.
Ubonelelo lwamandla ombane ozinzileyo (ubonelelo lombane oluzinzileyo) sisixhobo sombane esinokubonelela ngombane ozinzileyo we-AC okanye we-DC kumthwalo, kubandakanywa unikezelo lwamandla ombane oluzinzileyo lwe-AC kunye nonikezelo lombane oluzinzileyo lwe-DC kwiindidi ezimbini.
2. Imfuneko yokusebenzisa izixhobo zombane ezilawulwayo.
Ngenkqubela phambili ekhawulezayo yoluntu, izixhobo ezisebenzisa umbane ziyanda imihla ngemihla.Nangona kunjalo, ukuguga kunye nophuhliso olusemva lwamaziko othumelo kunye nokuhanjiswa kwamandla, kunye noyilo olulambathayo kunye nokungonelanga kombane kubangela ukuba amandla ombane omsebenzisi wokugqibela abephantsi kakhulu, ngelixa abasebenzisi bentambo besoloko benombane ophezulu.Kwizixhobo ezisebenzisa amandla, ngakumbi izixhobo ezikumgangatho ophezulu kunye nezichanekileyo ezineemfuno ezingqongqo zombane, kuba ngathi azifakwanga kwi-inshorensi.
Amandla ombane angazinzanga anokubangela ukwenzakala okubulalayo okanye ukungasebenzi kakuhle kwezixhobo, okuchaphazela imveliso, kubangele ukulibaziseka kokuhanjiswa, umgangatho ongazinzanga, kunye nezinye ezininzi ilahleko.Ngelo xesha, ikhawuleza ukuguga kwezixhobo, ichaphazela ubomi bayo benkonzo, kwaye ide itshise izixhobo, ukwenzela ukuba umniniyo abhekane nengxaki yokufuna ukulungiswa okanye ukuhlaziya izixhobo kwixesha elifutshane, elichitha izixhobo;kwiimeko ezimandundu, iingozi zokhuseleko zide zenzeke, zibangele ilahleko engenakubalwa.
3. Unikezelo lombane olulawulwa yi-DC.
Ikwabizwa ngokuba yi-DC voltage regulator.I-voltage yayo yokubonelela ubukhulu becala yi-AC yombane, xa i-voltage ye-AC yonikezelo lombane okanye i-output load resistance resistance, i-voltage ephuma ngokuthe ngqo yomlawuli inokugcinwa izinzile.Iiparamitha zesilawuli sombane kukuzinza kwamandla ombane, i-ripple coefficient, kunye nesantya sokuphendula.Owokuqala ubonisa umphumo wenguqu kwigalelo lombane kwi-voltage ephumayo.I-coefficient ye-ripple ibonisa ubungakanani becandelo le-AC lombane wokuphuma phantsi kweemeko zokusebenza ezilinganisiweyo;okokugqibela kubonisa ixesha elifunekayo ukuze i-voltage ibuyele kwixabiso layo eliqhelekileyo xa i-voltage yegalelo okanye umthwalo utshintsha kakhulu.Umlawuli wombane we-DC wahlulwe ngokweendidi ezimbini: i-continuous conductive kunye nohlobo lokutshintsha.Eyangaphambili yi-frequency transformer ukuya kwisigaba esinye okanye kwisigaba sesithathu sombane we-AC ukuya kwixabiso elifanelekileyo, emva koko ilungiswe, ihluzwe, ukufumana amandla e-DC angazinzanga, kwaye emva koko nge-voltage regulator circuit ukufumana i-voltage ezinzileyo (okanye yangoku).Olu hlobo lomgca wokubonelela ngombane lulula, i-ripple incinci, ukuphazamiseka okulinganayo kuncinci, kodwa umthamo mkhulu, izinto ezisetyenziswayo zininzi, kwaye ukusebenza kakuhle kuphantsi (kaninzi ngaphantsi kwe-40% ukuya kwi-60%).Le yokugqibela ilawula i-voltage ephumayo ngokutshintsha umlinganiselo wokuvula/ucima wento yokulungelelanisa (okanye utshintshe) ukufezekisa ukulawulwa kwamandla ombane.Olu hlobo lonikezelo lwamandla lusebenzisa amandla amancinci kwaye lusebenza kakuhle malunga nama-85%.
Ukusetyenziswa kwe-4.DC yesilawuli sombane.
Isilawuli sombane we-DC sisetyenziswa ngokubanzi kukhuselo lwesizwe, uphando lwezenzululwazi, iiyunivesithi kunye neekholeji, iilabhoratri, amashishini oshishino kunye nemigodi, i-electrolysis, i-electroplating, izixhobo zokutshaja, kunye nolunye unikezelo lombane lweDC.
5.Inkcazo ye-LM5010A
I-LM5010Ax i-step-down switching regulator yinguqulelo ephuculweyo ye-LM5010 kunye noluhlu olusebenzayo lwegalelo olwandisiweyo ukuya kwi-6-V ubuncinane.I-LM5010Ax ifaka yonke imisebenzi efunekayo ukuphumeza umlawuli wexabiso eliphantsi, elisebenzayo, elinokubonelela ngokugqithiswa kwe-1-A yomthwalo wangoku.Lo mlawuli we-high-voltage udibanisa i-N-Channel Buck Switch, kwaye ifumaneka kwi-10-pin ephuculweyo ye-WSON kunye ne-14-pin ye-HTSSOP iiphakheji.Iskim solawulo lwe-ON-time eqhubekayo asifuni mbuyekezo ye-loop ekhokelela ekuphenduleni komthwalo okhawulezayo kunye nokuphunyezwa kwesekethe lula.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.
