Nekukura kuri kuita simba reAI computing, zvinodiwa kuti DC-DC converter yema server motherboards iwane simba rakasimba zviri kuramba zvichiwedzera kuomarara.
Kukura kwakanyanya kwezvinodiwa pakugadzirisa data reAI kunoita kuti pave nekudiwa kwakanyanya pamodule yekutonga simba rema server motherboards. Sechikamu chekushandura simba guru, DC-DC converter inofanira kushandura nemazvo 12V high-voltage DC power kuita low-voltage power (yakadai se1V, 1.2V) inodiwa nezvikamu zvakaita seCPU neGPU. Kugadzikana kwayo kunotarisa zvakananga kuvimbika kweAI computing power.
Yongming Electronics' NPC series yema multilayer polymer solid aluminum electrolytic capacitors, ane ESR values dzawo dzakaderera, anonyatsoenderana nezvinodiwa zve server motherboard DC-DC converters.
01 Ultra-Low ESR: Dombo rekona reAI Server Kugadzikana
Simba remuchina mumwe chete rinogadzirwa neseva panguva yekushanda rinogona kusvika pamusoro pe130A. Panguva ino, ma capacitor anofanira kuita basa rakakosha mukuchengetedza uye kusefa simba.
ma capacitor e-ymin, ane resistance yakaderera kwazvo ye equivalent series (ESR), anogona kukurumidza kupindura kune shanduko dzinoitika panguva imwe chete kubva kumachipisi eAI, zvichiita kuti magetsi abude zvakanaka kunyangwe paine mitoro inochinja-chinja.
ESR yakaderera haingodzikisi chete kurasikirwa kwemagetsi uye inovandudza mashandiro ekushandura magetsi asiwo inoderedza kugadzirwa kwekupisa, zvichiita kuti sevha ishande zvakanaka uye nguva dzose pasi pemitoro yakawanda uye nzvimbo dzakaoma dzekushandisa.
02 Kushivirira Kwenguva Inoyerera: Kiyi Yekubata Mitoro Isingatarisirwi
Kana mutoro wemakombiyuta weAI servers uchichinja-chinja pakati pema "peaks" nema "troughs", sisitimu yemagetsi inoda simba rakasimba rekukwanisa kudzoreredza data nekukurumidza.
Ma capacitor eYMIN ane simba rakanaka rekutsungirira ma ripple current; capacitor imwe chete inogona kutsungirira ma inrush currents makuru kwazvo anodarika 20A, zvichibatsira sevha kugadzirisa matambudziko ekuremerwa zvakanyanya uye kudzivirira kusagadzikana kwesystem kunokonzerwa nekuchinja kwe current kamwe kamwe.
Kushivirira kwakasimba kweripple current kunoita kuti ma capacitor ashande zvakanaka uye zvakavimbika munzvimbo dzakaoma, achidzivirira kukuvara kwekushushikana kunokonzerwa nekuchinja kwemagetsi kamwe kamwe uye kuwedzera hupenyu hwesevha.
03 Mhinduro Dzediki Dzenzvimbo Dzinopisa Zvakanyanya
Kuti zvikwanisike kuwedzera kwehuwandu hwesimba reAI servers, YMIN capacitors inoshandisa dhizaini diki, ichipa kugona kukuru kwekuchengetedza simba munzvimbo diki.
Dhizaini yacho inoenderana nemaitiro ekuva nemasevha matete, zvichichengetedza nzvimbo inokosha mu chassis yemasevha ane huwandu hwakawanda.
Ma capacitor e ymin anochengetedza hupenyu hurefu hwemaawa anopfuura 3000 kunyangwe pa105℃, achisvika pahurefu hwemaawa 2000 pa125℃, uye achigonesa kushanda kwemaawa 24/7 pasina kukanganiswa.
Hunhu uhwu hunobvumira ma capacitor kutsungirira mamiriro ekupisa kwepamusoro-soro enzvimbo dzedata, zvichiita kuti sisitimu ishande zvakanaka kwenguva refu.
Kuwanda kwema "miniaturization", huwandu hwe "capacitance density", "low ESR", uye hupenyu hurefu hwema "YMIN capacitors" zvinoita kuti ive sarudzo yakakodzera kune vanoshandura ma "DC-DC" pama "AI server motherboards". Nekushandiswa kwakapararira kwezvinhu zve "semiconductor" zvechizvarwa chechitatu, simba re "server" rinoda ma "capacitors" anoshanda zvakanyanya.
Ma capacitor eYMIN anoshandiswa zvinobudirira mukupa simba remagetsi epasi rose re4.5kW ne8.5kW, zvichiita kuti kushanda zvakanaka kupfuure 97%, zvichipa rutsigiro rwakavimbika kune simba riri kukura reAI data centers.
