Shamwari mainjiniya, wakambosangana nerudzi urwu rwekukundikana kwe "phantom"? Iyo yakanyatsogadzirwa data data gedhi yakaedzwa zvakakwana mulabhu, asi mushure megore rimwe kana maviri rekuiswa kwevanhu vakawanda uye kushanda kwemunda, mabheti chaiwo akatanga kusangana nekurasikirwa kwepaketi kusingatsananguriki, kudzimwa kwemagetsi, uye kunyange kutangazve. Chikwata chesoftware chakanyatso ongorora kodhi, uye timu yehardware yakadzokorodza kutarisa, pakupedzisira ichishandisa zviridzwa zvakaringana kuziva akonzeresa: ruzha-ruzha pane njanji yemagetsi.
YMIN Multilayer Capacitor Solution
- Root Cause Technical Analysis - Ngationgororei zvakadzama mukati me "pathology analysis." Iko kushandiswa kwesimba kweCPU / FPGA machipisi mumagedhi emazuva ano anochinja zvakanyanya, achigadzira akawanda akakwira-frequency ikozvino harmonics. Izvi zvinoda simba ravo rekubvisa network, kunyanya macapacitor akawanda, kuve neakanyanya kuderera akaenzana akateedzana kuramba (ESR) uye yakakwirira ripple ikozvino kugona. Kutadza mashandiro: Pasi pekushushikana kwenguva refu kwekushisa kwakanyanya uye yakakwira ripple ikozvino, iyo electrolyte-electrode interface yeakajairika polymer capacitor inoramba ichidzikisira, zvichiita kuti ESR iwedzere zvakanyanya nekufamba kwenguva. Kuwedzera kweESR kune mhedzisiro mbiri dzakakomba: Kudzikira kusefa kushanda: Zvinoenderana neZ = ESR + 1/ωC, pakakwirira frequency, impedance Z inonyanya kutsanangurwa neESR. Sezvo ESR ichiwedzera, kukwanisa kwe capacitor kudzvinyirira ruzha rwepamusoro-soro kunoderera zvakanyanya. Kuwedzera kuzvipisa: Ripple ikozvino inogadzira kupisa mhiri kweESR (P = I²_rms * ESR). Iyi tembiricha inokwira inomhanyisa kuchembera, ichigadzira yakanaka mhinduro loop iyo inozopedzisira yatungamira kune premature capacitor kutadza. Mhedzisiro: Iyo yakakundikana capacitor array haigone kupa yakakwana kuchaja panguva yekuchinja kwemutoro wenguva pfupi, uye haigone kusefa kunze kwepamusoro-frequency ruzha rwunogadzirwa nemagetsi ekuchinja. Izvi zvinokonzeresa glitches uye kudonha muiyo chip's supply voltage, zvichitungamira kune logic kukanganisa.
- YMIN Solutions uye Maitiro Mabhenefiti - YMIN's MPS akateedzana multilayer solid-state capacitors akagadzirirwa aya anodiwa maapplication.
Kubudirira kwemaitiro: Iyo multilayer maitiro inobatanidza akawanda madiki akasimba-state capacitor machipi akafanana mukati mepakeji imwe. Ichi chimiro chinogadzira parallel impedance mhedzisiro kana ichienzaniswa neiyo hombe capacitor, ichideredza ESR uye ESL (yakaenzana akatevedzana inductance) kusvika kumazinga akaderera zvakanyanya. Semuenzaniso, iyo MPS 470μF/2.5V capacitor ine ESR yakaderera sepasi pe3mΩ.
Chigadzirwa Chevimbiso: Solid-state polymer system. Uchishandisa yakasimba conductive polymer, inobvisa njodzi yekudonha uye inopa yakanakisa tembiricha-frequency maitiro. ESR yayo inosiyana zvishoma pane yakafara tembiricha renji (-55°C kusvika +105°C), zvichinyatsogadzirisa zvipimo zveupenyu zvemvura/gel electrolyte capacitors.
Kuita: Ultra-yakaderera ESR inoreva yakakura ripple ikozvino kubata kugona, inoderedza mukati tembiricha kukwira, uye inovandudza system MTBF (kureva nguva pakati pekutadza). Yakanakisa yakakwirira-frequency mhinduro inosefa kunze kweMHz-level switching ruzha, ichipa yakachena voltage kune chip.
Isu takaita bvunzo dzekuenzanisa pabhodhi remutengi rakashata:
Waveform kuenzanisa: Pasi pemutoro mumwechete, iyo peak-to-peak ruzha nhanho yeyakatanga musimboti njanji yakasvika pakukwirira se240mV. Mushure mekutsiva YMIN MPS capacitors, ruzha rwakadzvanywa kusvika pasi pe60mV. Iyo oscilloscope waveform inoratidza zvakajeka kuti voltage waveform yave yakatsetseka uye yakagadzikana.
Tembiricha yekukwira bvunzo: Pasi pemutoro wakazara ripple ikozvino (ingangoita 3A), tembiricha yepasi peyakajairika capacitor inogona kusvika pamusoro pe95 ° C, nepo tembiricha yeYMIN MPS capacitors inongotenderedza 70 ° C, kudzikiswa kwekushisa kweinopfuura 25 ° C. Kukurumidza kuyedza hupenyu: Payero yakayerwa tembiricha ye105 ° C uye yakayerwa ripple ikozvino, mushure memaawa 2000, chiyero chekuchengetedza simba chakasvika> 95%, ichipfuura zvakanyanya chiyero cheindasitiri.
- Mamiriro Ekushandisa uye Yakakurudzirwa Models - YMIN MPS Series 470μF 2.5V (Dimensions: 7.3 * 4.3 * 1.9mm). Yavo yekupedzisira-yakaderera ESR (<3mΩ), yakakwira ripple ikozvino rating, uye yakakura yekushanda tembiricha renji (105 ° C) inovaita hwaro hwakavimbika hwemagadzirirwo emagetsi emagetsi epamusoro-yekupedzisira network yekutaurirana michina, maseva, masisitimu ekuchengetedza, uye maindasitiri ekudzora mamabhodhi.
Mhedziso
Kune vagadziri vehardware vanovavarira kuvimbika kwekupedzisira, kupatsanurwa kwemagetsi haisisiri nyaya yekusarudza iyo chaiyo capacitance kukosha; inoda kutarisisa zvakanyanya kune zvine simba paramita senge capacitor's ESR, ripple ikozvino, uye kugadzikana kwenguva refu. YMIN MPS multilayer capacitors, kuburikidza nehunyanzvi hwekuita uye matekinoroji, inopa mainjiniya chishandiso chine simba chekukunda matambudziko eruzha rwemagetsi. Tinovimba iyi yakadzama ongororo yehunyanzvi ichakupa iwe ruzivo. Kune matambudziko ekushandisa capacitor, tendeukira kuYMIN.
