Shamwari dzangu, makambosangana nedambudziko re "phantom" rakadai here? Gateway yedata center yakagadzirwa zvakanaka yakaedzwa zvakanaka murabhoritari, asi mushure megore rimwe kana maviri ekushandiswa kwakawanda uye kushanda mumunda, mapoka chaiwo akatanga kurasikirwa nemapaketi asinganzwisisike, kudzimwa kwemagetsi, uye kutotangazve. Chikwata chesoftware chakaongorora kodhi yacho zvakadzama, uye timu yehardware yakaongorora kakawanda, pakupedzisira ichishandisa zvishandiso zvine hungwaru kuona chikonzero: ruzha rwepamusoro-soro pachiteshi chemagetsi chepakati.
Mhinduro yeYMIN Multilayer Capacitor
- Root Cause Technical Analysis – Ngatinyatsoongororai "pathology analysis" iri pasi apa. Kushandiswa kwesimba reCPU/FPGA chips muma gateways emazuva ano kunochinja-chinja zvikuru, zvichigadzira ma high-frequency current harmonics akawanda. Izvi zvinoda kuti ma network avo e power disacoupling, kunyanya ma bulk capacitors, ave ne high equal series resistance (ESR) uye high ripple current capacity. Kukundikana: Pasi pekumanikidzwa kwenguva refu kwe high temperature uye high ripple current, electrolyte-electrode interface yema ordinary polymer capacitors inoramba ichiderera, zvichiita kuti ESR iwedzere zvakanyanya nekufamba kwenguva. Kuwedzera kweESR kune mhedzisiro miviri yakakosha: Kudzikira kwekushanda kwekusefa: Sekureva kwaZ = ESR + 1/ωC, pama frequency akakwira, impedance Z inonyanya kutsanangurwa neESR. Sezvo ESR ichiwedzera, kugona kwe capacitor kudzvinyirira high-frequency noise kunodzikira zvakanyanya. Kuwedzera kwe self-heat: Ripple current inogadzira kupisa muESR (P = I²_rms * ESR). Kukwira kwekushisa uku kunokurumidza kukwegura, zvichigadzira positive feedback loop iyo inozopedzisira yakonzera kukundikana kwe capacitor nguva isati yakwana. Mugumisiro wacho: Capacitor array yakakundikana haigone kupa chaji yakakwana panguva yekuchinja kwemutoro wenguva pfupi, uye haigone kusefa ruzha rwemafrequency akakwira rwunobva pakuchinja kwesimba remagetsi. Izvi zvinokonzera zvikanganiso uye kudzikira kwevoltage yesimba remachipu, zvichikonzera zvikanganiso zvelogic.
- Mhinduro dzeYMIN uye Mabhenefiti Emaitiro – YMIN's MPS series multilayer solid-state capacitors yakagadzirirwa mashandisirwo aya akaomarara.
Kubudirira kwechimiro: Maitiro e multilayer anobatanidza ma small solid-state capacitor chips akawanda ari pamwe chete mukati me package imwe chete. Chimiro ichi chinogadzira parallel impedance effect zvichienzaniswa ne capacitor hombe imwe chete, zvichideredza ESR ne ESL (equivalent series inductance) kusvika padanho rakaderera zvakanyanya. Semuenzaniso, MPS 470μF/2.5V capacitor ine ESR yakaderera kusvika pasi pe3mΩ.
Vimbiso yezvinhu: Sisitimu yepolymer yakasimba. Ichishandisa polymer yakasimba inofambisa mvura, inobvisa njodzi yekubuda kwemvura uye inopa hunhu hwakanaka hwekupisa-frequency. ESR yayo inosiyana zvishoma pamhando dzakasiyana dzekupisa (-55°C kusvika +105°C), ichigadzirisa zvakanyanya miganhu yehupenyu hwema capacitor emvura/gel electrolyte.
Kushanda: Ultra-low ESR zvinoreva kugona kukuru kwekubata ma ripple current, kunoderedza kukwira kwekupisa kwemukati, uye kunovandudza system MTBF (nguva iri pakati pekutadza kushanda). Mhinduro yepamusoro-soro inosefa ruzha rwekuchinja rweMHz-level, ichipa voltage yakachena ku chip.
Takaita bvunzo dzekuenzanisa pabhodhi reamai remutengi raive risina kunaka:
Kuenzanisa kweWaveform: Pasi pemutoro mumwe chete, ruzha rwepamusoro-soro rwesimbi yepakutanga yesimba remagetsi rwakasvika pa240mV. Mushure mekutsiva ma capacitor eYMIN MPS, ruzha rwakaderedzwa kusvika pasi pe60mV. Oscilloscope waveform inoratidza zvakajeka kuti voltage waveform yave yakatsetseka uye yakagadzikana.
Kuyedzwa kwekukwira kwekushisa: Kana paine simba rakazara rema ripple current (inenge 3A), tembiricha yepamusoro yema capacitor akajairwa inogona kusvika pamusoro pe95°C, nepo tembiricha yepamusoro yema capacitor eYMIN MPS iri pa70°C chete, kudzikira kwekupisa kwepamusoro kwe25°C. Kuyedzwa kwehupenyu hwakakurumidza: Patembiricha yakayerwa ye105°C uye yakayerwa ma ripple current, mushure memaawa 2000, chiyero chekuchengetedza kugona chakasvika >95%, chinopfuura zvakanyanya mwero weindasitiri.
- Maitiro Ekushandisa uye MaModheru Anokurudzirwa – YMIN MPS Series 470μF 2.5V (Zviyero: 7.3*4.3*1.9mm). ESR yavo yakaderera zvakanyanya (<3mΩ), high ripple current rating, uye wide operating temperature range (105°C) zvinoita kuti ive hwaro hwakavimbika hwekugadzira magetsi epakati mumidziyo yekukurukurirana yenetwork yepamusoro, maseva, masisitimu ekuchengetera, uye mamaboard ekutonga eindasitiri.
Mhedziso
Kune vagadziri vemidziyo yemagetsi vari kuedza kuvimbika zvakanyanya, kupatsanura magetsi hakusi kungosarudza kukosha kwe capacitance kwakakodzera; zvinoda kutarisisa zvakanyanya kune ma dynamic parameters akadai se ESR ye capacitor, ripple current, uye kugadzikana kwenguva refu. YMIN MPS multilayer capacitors, kuburikidza nehunyanzvi hwekuvaka uye matekinoroji, inopa mainjiniya chishandiso chine simba chekukunda matambudziko eruzha rwemagetsi. Tinovimba kuti ongororo iyi yakadzama yehunyanzvi ichakupa ruzivo. Kune matambudziko ekushandisa capacitor, shanyira YMIN.
