Izisombululo zePCB Zokulawula Amandla Okuzinzile Kwezogesi

Idizayini ye-PCB yokulawula amandla inquma ukuthi amasekhethi azwelayo athola amandla azinzile, angenamsindo noma ahlupheke ngenxa yokuyeka ukufunda, ama-oscillations, nokwehluleka ngaphambi kwesikhathi. Kusukela kuzilawuli ezilula zomugqa kuya ezinhlelweni eziyinkimbinkimbi zokuphatha amandla edijithali, ukuqaliswa okufanele kwe-PCB kwenza umehluko phakathi kokusebenza okucacisiwe nokusebenza kwangempela.

Isetshenziswa nini i-Linear vs Switching Regulator ku-PCB Design

Izilawuli zomugqa zibonakala zilula kodwa zidinga isakhiwo esicophelelayo ukuze sizinze. Izilawuli zokushintsha zinikeza ukusebenza kahle kodwa zidinga ukwakheka okuhlukile kwe-PCB.

Okubalulekile kwe-PCB yesilawuli sokulawula amandla:

• Ama-capacitor okokufaka/okukhiphayo ngaphakathi kuka-10mm wamaphini okulawula
• Indawo yethusi eyanele yokuqeda ukushisa
• Inzwa ka-Kelvin yokulawulwa kwe-voltage ekude
• Ukubekwa phansi kwenkanyezi kuvimbela izihibe zomhlabathi

Ukushintsha amaqiniso esilawuli:

• Ukubekwa kwengxenye kunquma ukusebenza kahle kanye ne-EMI
• Umzila wempendulo udinga amasu okuvikela umsindo
• Izindiza eziningi ezingaphansi komhlaba zidinga ukuxhumana okunesu
• Ukuphatha okushisayo kubalulekile naphezu kokusebenza kahle okuphezulu

Ukuze uthole amasekethe e-analog anembile, sivame ukuhlanganisa izindlela: ukushintsha i-pre-regulator ukuze kusebenze kahle kulandelwe i-linear post-regulation yomsindo ophansi. Le ndlela ehlanganisiwe isebenza kahle futhi kumadizayini kagesi e-Power Amplifier PCB.

Idizayini Yesekhethi Elandelanayo Yokunikezela Ngamandla ye-FPGA

Amasistimu esimanje adinga ama-voltage rails amaningi anezidingo ezithile zokulandelana. Ama-FPGA angase adinge i-core voltage ngaphambi kwe-voltage ye-I/O. Amasekhethi e-analog adinga ukulandela ngomkhondo kajantshi we-symmetric. Ukulandelanisa okungalungile kubangela ukulimala kwe-latch up noma ingxenye.

Ukulandelanisa amasu okusebenzisa:

• Ama-IC elandelanayo azinikele ahlinzeka ngokulibaziseka okuhlelekayo
• Amanethiwekhi e-RC anikeza isikhathi esilula kodwa esincike kuzinga lokushisa
• Ukulawulwa kwedijithali kunika amandla ukulandelana okunemibandela okuyinkimbinkimbi
• Ukuphatha amaphutha kufanele kuvalwe ngokuphephile ngokuhlehlisa

Kumiklamo ye-PCB yokulawula amandla eyinkimbinkimbi, sisebenzisa ukuqinisekiswa kokulandelana okungadingekile. Izinselele ezifanayo zokulandelana zivela ku -Power Electronics PCB yezinhlelo zokusebenza zokulawula izimoto.

Imihlahlandlela Yesakhiwo Sephoyinti Lokulayishwa Kwe-PCB

Ukusabalalisa i-voltage ephezulu kanye nokulawula endaweni yokulayisha kuthuthukisa ukusebenza kahle nokusabela kwesikhashana. Kodwa izilawuli ze-POL eduze namasekhethi azwelayo zidinga ukuhlanganiswa ngokucophelela ukuvimbela umjovo womsindo.

• Ukushintsha ukukhetha kwefrikhwensi kugwema ukuphazamiseka ekusebenzeni kokujikeleza
• Ukuhlunga okokufaka kuvimbela ukusakazeka komsindo okwenziwe
• Ukukhethwa kwe-capacitor okukhiphayo kulinganisa impendulo yesikhashana nokuzinza
• Ukuhlangana okushisayo phakathi kwezilawuli kubangela ukusebenzisana okungalindelekile

Imiklamo yakamuva yeprosesa isebenzisa abalawuli be-POL abangaphezu kuka-20. Imiklamo yethu isebenzisa ukuphathwa kokushisa okusekelwe endaweni ukuvimbela ukwehluleka kokushisa okukhuphukayo. Lawa masu okulawula okuningi asebenza nasezinhlelweni ze-PCB zamandla aphezulu.

Uyiklama kanjani i-DVS Circuit for Prosesa Power Supply

Amaphrosesa esimanje ayahluka i-voltage ngomthwalo wokusebenza ukuze kusetshenziswe amandla. Idizayini ye-PCB ithinta kakhulu impendulo yesikhashana.

• Nciphisa amandla okukhiphayo ukuze ushintshe i-voltage esheshayo
• Beka amanethiwekhi empendulo yokuvikeleka komsindo
• Sebenzisa izindlela ezihlukene zempendulo ye-AC ne-DC
• Sebenzisa inzwa eyirimothi ehlukile ukuze uthole ukunemba

Kuzinhlelo zokusebenza ze-PCB ze-DC-DC Converter zedivayisi yeselula , i-DVS yandisa impilo yebhethri ngo-30%.

Ukukhethwa kwe-LDO Capacitor Ukuvimbela Ukuguquguquka

Izilawuli ze-Low-dropout (LDOs) zinikeza ukulawulwa kwamandla ahlanzekile, anomsindo ophansi, kodwa ukukhethwa kwe-capacitor kubalulekile ekuzinzeni. I-ESR engalungile noma ukukhetha kwesakhiwo kungaholela ekwehleni nasekusebenzeni okonakele.

• Qinisekisa izimfuneko ze-ESR — amanye ama-LDO adinga ama-capacitor ngaphakathi kwebanga elincane le-ESR ukuze azinze
• Engeza i-resistor yochungechunge encane uma usebenzisa ama-ceramic capacitor e-ECR aphansi kakhulu ukuze uvimbele ukukhala
• Nciphisa i-PCB trace inductance endleleni yokuphumayo ukuze ulondoloze imajini yesigaba
• Qinisekisa idizayini efanelekile yokushisa kwama-LDO amanje ukuze ugweme ukuvala shaqa okushisayo

Ukukhetha inethiwekhi efanele ye-capacitor kusiza ukuvimbela ukudlidliza futhi kuqinisekisa ukulawulwa okuthembekile. Lezi zimiso zokuzinza ziyasebenza futhi ekunxephezelweni kwe -switch mode Power Supply PCB control loop, lapho ukukhethwa kwezingxenye kuthinta ngqo i-EMI kanye nokusebenza kahle.

Ukuqaliswa Kwe-PMBus ku-PCB Yokuhlinzeka Amandla Weseva

I-PMBus inika amandla ukuphathwa kwamandla edijithali nge-telemetry yesikhathi sangempela, ukugawulwa kwamaphutha, nokucushwa okukude—okubalulekile ekuthembekeni kwesikhungo sedatha. Ukuqaliswa ngempumelelo kudinga ihadiwe ecophelelayo kanye nomklamo we-PCB.

• Sebenzisa izindiza ezihlukene ze-analog nedijithali, ezixhunywe endaweni eyodwa ukuze ugweme ukuhlangana komsindo
• Sebenzisa ukuhlunga okunezigaba eziningi ukuze unikeze amandla ahlanzekile, azinzile esilawuli sedijithali
• Sebenzisa i-galvanic isolation yokuxhumana kwe-PMBus lapho unika amandla izinto ezintantayo
• Engeza i-watchdog kanye nokuvikela okungafuneki ukuze uvikele ukuvala i-firmware

Ukuhlanganiswa okufanele kwe-PMBus kuvumela ukuqapha okude, ukulungiswa kokubikezela, kanye nokusebenza kwesikhathi esingcono kwesistimu. Lawa masu okulawula edijithali awusizo ngokulinganayo ekwakhiweni kwe-PCB ye-Power Inverter , okwenza kube lula ukuxilongwa kwamaphutha okuhlakaniphile kanye nokusebenza kahle kwamandla okuthuthukisiwe.

I-Power Supply PCB Layisha Izindlela Zokuhlola Zesikhashana

Ukuhlolwa okuphelele komthwalo wesikhashana kubalulekile ukuze kuqinisekiswe ukuqina nokusebenza kwesiphakeli ngaphansi kwezimo zengcindezi yomhlaba wangempela ngaphambi kokukhiqizwa ngobuningi.

• Linganisa impendulo yesinyathelo sokulayisha ngamanani ahlukahlukene abulalayo ukuze uqinisekise idizayini yesinxephezelo
• Yethula amadiphu kagesi okokufaka kanye nokunyuka ukuze uqinisekise amandla okugibela
• Yenza ibhayisikili elishisayo ngenkathi ungaphansi komthwalo ogcwele ukuze uveze ubuthakathaka obuhlangene be-solder noma ingxenye
• Linganisa amamajini okuzinza kuwo wonke amazinga okushisa nokweqisa kokubekezelela ingxenye

Izinsizakalo zethu zokuhlanganisa i-PCB zihlanganisa ukuhlolwa kwesitimela sikagesi okuzenzakalelayo, okusiza ekubambeni izinkinga zesikhashana noma zokuzinza kusenesikhathi. Lokhu kuqinisekisa ukuthi ibhodi ngalinye lihlangabezana nezindinganiso zokusebenza ngaphambi kokuthunyelwa.
