Manjineli, ngaba nikhe nadibana nolu hlobo lokusilela "kwe-phantom"? Isango leziko ledatha eliyilwe kakuhle livavanywe kakuhle kwilebhu, kodwa emva konyaka omnye okanye emibini yokusasazwa okukhulu kunye nokusebenza kwintsimi, amaqela athile aqala ukulahleka kweepakethi ngendlela engaqondakaliyo, ukucima kombane, kunye nokuqalisa kwakhona. Iqela lesoftware liphande kakuhle le khowudi, kwaye iqela lehardware liyijongile ngokuphindaphindiweyo, ekugqibeleni lisebenzisa izixhobo ezichanekileyo ukuchonga unobangela: ingxolo ephezulu kwi-core power rail.
Isisombululo se-YMIN Multilayer Capacitor
- Uhlalutyo loBugcisa lweMpembelelo – Masijonge nzulu kwi-"pathology analysis" esisiseko. Ukusetyenziswa kwamandla okuguquguquka kweetships zeCPU/FPGA kwiindlela zanamhlanje kuyatshintshatshintsha kakhulu, kuvelisa iiharmonics ezininzi ze-high-frequency current. Oku kufuna ukuba iinethiwekhi zazo zokwahlulahlula amandla, ingakumbi ii-bulk capacitors, zibe nokumelana okuphantsi kakhulu kwe-equivalent series resistance (ESR) kunye nokukwazi kwe-high ripple current. Indlela yokusilela: Phantsi koxinzelelo lwexesha elide lobushushu obuphezulu kunye ne-high ripple current, i-electrolyte-electrode interface yee-polymer capacitors eziqhelekileyo iyaqhubeka nokonakala, nto leyo ebangela ukuba i-ESR inyuke kakhulu ngokuhamba kwexesha. Ukwanda kwe-ESR kunemiphumo emibini ebalulekileyo: Ukuncipha kokusebenza kokucoca: Ngokutsho kwe-Z = ESR + 1/ωC, kwii-frequency eziphezulu, i-impedance Z imiselwa kakhulu yi-ESR. Njengoko i-ESR isanda, amandla e-capacitor okunciphisa ingxolo ye-high-frequency ayancipha kakhulu. Ukwanda kokuzifudumeza: I-Ripple current ivelisa ubushushu kwi-ESR (P = I²_rms * ESR). Oku kunyuka kobushushu kukhawulezisa ukuguga, kudala i-feedback loop eyakhayo ekugqibeleni ekhokelela ekusileleni kwe-capacitor ngaphambi kwexesha. Isiphumo: I-capacitor array engasebenziyo ayinakubonelela ngetshaja eyaneleyo ngexesha lotshintsho lomthwalo wesikhashana, kwaye ayinakuhluza ingxolo ephezulu eveliswa lunikezelo lwamandla olutshintshayo. Oku kubangela iingxaki kunye nokwehla kwevolthi yonikezelo lwetshiphu, nto leyo ekhokelela kwiimpazamo zengqiqo.
- Izisombululo zeYMIN kunye neeNzuzo zeNkqubo – Ii-capacitor ze-MPS ze-YMIN ze-MPS series multilayer solid-state zenzelwe ezi zicelo zinzima.
Uphuhliso lwesakhiwo: Inkqubo ye-multilayer idibanisa ii-chips ezininzi ezincinci ze-solid-state capacitor ezihambelanayo ngaphakathi kwiphakheji enye. Olu lwakhiwo ludala isiphumo se-impedance esihambelanayo xa kuthelekiswa ne-capacitor enkulu enye, nto leyo enciphisa i-ESR kunye ne-ESL (i-equivalent series inductance) ukuya kumanqanaba aphantsi kakhulu. Umzekelo, i-MPS 470μF/2.5V capacitor ine-ESR ephantsi njenge-3mΩ.
Isiqinisekiso sezinto: Inkqubo yepolymer eqinileyo. Isebenzisa ipolymer eqinileyo eqhubayo, isusa umngcipheko wokuvuza kwaye inika iimpawu ezintle kakhulu zobushushu. I-ESR yayo iyahluka kancinci kuluhlu olubanzi lobushushu (-55°C ukuya ku-+105°C), ngokusisiseko ijongana nemida yobomi bee-capacitors ze-electrolyte ezingamanzi/ijeli.
Ukusebenza: I-ESR ephantsi kakhulu ithetha ukuba amandla okuphatha umbane we-ripple aphezulu, inciphisa ukunyuka kobushushu bangaphakathi, kwaye iphucula i-MTBF yenkqubo (ixesha eliphakathi phakathi kokusilela). Impendulo egqwesileyo ye-high-frequency ihluza ngokufanelekileyo ingxolo yokutshintsha ye-MHz, inika i-voltage ecocekileyo kwi-chip.
Senze uvavanyo oluthelekisayo kwibhodi yomama yomthengi eneengxaki:
Uthelekiso lwe-Waveform: Phantsi komthwalo ofanayo, inqanaba lengxolo ye-peak-to-peak ye-core power rail yokuqala ifikelele kwi-240mV. Emva kokutshintsha ii-capacitors ze-YMIN MPS, ingxolo yancitshiswa yaya ngaphantsi kwe-60mV. I-oscilloscope waveform ibonisa ngokucacileyo ukuba i-voltage waveform igudile kwaye izinzile.
Uvavanyo lokunyuka kobushushu: Phantsi komthwalo opheleleyo we-ripple current (malunga ne-3A), ubushushu bomphezulu wee-capacitors eziqhelekileyo bunokufikelela ngaphezulu kwe-95°C, ngelixa ubushushu bomphezulu wee-capacitors ze-YMIN MPS bumalunga ne-70°C kuphela, ukwehla kokunyuka kobushushu okungaphezulu kwe-25°C. Uvavanyo lobomi olukhawulezileyo: Kubushushu obulinganisiweyo be-105°C kunye nombane we-ripple olinganisiweyo, emva kweeyure ezingama-2000, izinga lokugcina amandla lifikelele ngaphezulu kwe-95%, lidlula kakhulu umgangatho woshishino.
- Imizekelo yoSetyenziso kunye neeModeli eziCetyisiweyo – YMIN MPS Series 470μF 2.5V (Ubukhulu: 7.3*4.3*1.9mm). I-ESR yazo ephantsi kakhulu (<3mΩ), umlinganiselo wamandla aphezulu, kunye nobubanzi bobushushu bokusebenza (105°C) zenza zibe sisiseko esithembekileyo soyilo lombane ophambili kwizixhobo zonxibelelwano zenethiwekhi eziphezulu, iiseva, iinkqubo zokugcina, kunye neebhodi zomama zolawulo lwemizi-mveliso.
Isiphelo
Kubayili bezixhobo zokusebenza abalwela ukuthembeka okuphezulu, ukwahlulahlula umbane akusekho nje ngumba wokukhetha ixabiso elifanelekileyo le-capacitance; kufuna ingqalelo enkulu kwiiparameter eziguqukayo ezifana ne-ESR ye-capacitor, i-ripple current, kunye nokuzinza kwexesha elide. Ii-capacitor ze-YMIN MPS ezininzi, ngokusebenzisa ubuchwepheshe obutsha bokwakha kunye nezinto, zibonelela iinjineli ngesixhobo esinamandla sokunqoba imingeni yengxolo yombane. Siyathemba ukuba olu hlalutyo lobuchwephesha olunzulu luya kukunika ulwazi. Ngemingeni yokusetyenziswa kwe-capacitor, jonga kwi-YMIN.
