Bahanga mu by’ubwubatsi, ese mwigeze muhura n’ubu bwoko bw’ikosa rya “fantom”? Irembo ry’amakuru ryakozwe neza ryageragejwe neza muri laboratwari, ariko nyuma y’umwaka umwe cyangwa ibiri ryoherejwe mu buryo bwinshi no mu bikorwa byaryo, amatsinda runaka yatangiye gutakaza paki mu buryo butangaje, umuriro ubura, ndetse no kongera gutangira. Itsinda rya porogaramu ryasuzumye neza iyo kode, maze itsinda rya hardware rigenzura kenshi, amaherezo rikoresha ibikoresho bigezweho kugira ngo rimenye nyirabayazana: urusaku rwinshi ku muhanda w’amashanyarazi.
Igisubizo cya YMIN Multilayer Capacitor
- Isesengura ry’Ubuhanga bw’Inkomoko y’Impamvu – Reka twige mu buryo bwimbitse “isesengura ry’indwara.” Ikoreshwa ry’imbaraga za CPU/FPGA chips mu nzira zigezweho rihindagurika cyane, rigatanga harmonics nyinshi za high-frequency current. Ibi bisaba ko imiyoboro yazo yo gukuraho ingufu, cyane cyane capacitors nyinshi, igira ubushobozi bwo kudahuza ingufu (ESR) n’ubushobozi bwo gukurura umuvuduko mwinshi. Uburyo bwo gutsindwa: Mu gihe kirekire cy’ubushyuhe bwinshi n’umuvuduko mwinshi w’amashanyarazi, electrolyte-electrode interface ya capacitors zisanzwe za polymer ikomeza kwangirika, bigatuma ESR yiyongera cyane uko igihe kigenda gihita. Ubwiyongere bwa ESR bugira ingaruka ebyiri zikomeye: Kugabanuka k’ubushobozi bwo kuyungurura: Dukurikije Z = ESR + 1/ωC, ku miyoboro miremire, impedance Z igenwa cyane na ESR. Uko ESR yiyongera, ubushobozi bwa capacitor bwo guhagarika urusaku rwa high-frequency buragabanuka cyane. Ubwiyongere bw’ubushyuhe: Ripple current ikora ubushyuhe muri ESR (P = I²_rms * ESR). Uku kwiyongera k’ubushyuhe kwihutisha gusaza, bigatuma habaho uburyo bwiza bwo gusubiza ibintu mu buryo butuma capacitor inanirwa vuba. Ingaruka: Capacitor yananiwe ntabwo ishobora gutanga charge ihagije mu gihe cy'impinduka z'umuzigo w'agateganyo, cyangwa ngo ishobore gushungura urusaku rwinshi ruterwa n'amashanyarazi ahindagurika. Ibi bitera imbogamizi no kugabanuka k'amashanyarazi ya chip, bigatera amakosa ya logic.
- Ibisubizo bya YMIN n'Ibyiza by'Uburyo bwo Gutunganya – Capacitors za YMIN zo mu bwoko bwa MPS series multilayer solid-state zagenewe izi porogaramu zikomeye.
Uburyo bwo gutera imbere mu miterere: Uburyo bwo guteranya ibice byinshi bito bya capacitor bihuza ibice byinshi bito bya capacitor bihurira hamwe mu ipaki imwe. Iyi miterere ikora ingaruka ya impedance ihuriranye ugereranije na capacitor imwe nini, bigabanura ESR na ESL (inductance ingana n'iyindi) ku rwego rwo hasi cyane. Urugero, capacitor ya MPS 470μF/2.5V ifite ESR iri munsi ya 3mΩ.
Ingwate y'ibikoresho: Sisitemu ya polymeri ikomeye. Ikoresheje polymeri ikomeye iyobora amashanyarazi, ikuraho ibyago byo kuva amazi kandi itanga imiterere myiza y'ubushyuhe. ESR yayo iratandukanye gato mu bushyuhe bwinshi (-55°C kugeza +105°C), by'umwihariko ikemura imbogamizi z'ubuzima bwa capacitors za electrolyte zikozwe mu mazi/gel.
Imikorere: ESR iri hasi cyane bivuze ubushobozi bwo gucunga umuyoboro w'amashanyarazi urimo amajwi menshi, bigabanya ukwiyongera k'ubushyuhe bw'imbere, kandi bikongera uburyo bwo gukoresha umuvuduko w'amashanyarazi (MTBF) (igihe kiri hagati y'igihe cyo gucika intege). Igisubizo cyiza cyane cya frequency yo hejuru gikemura neza urusaku rwo guhinduranya amashanyarazi mu rwego rwa MHz, bigatanga voltage nziza kuri chip.
Twakoze ibizamini byo kugereranya kuri motherboard y'umukiriya yari ifite ikibazo:
Igereranya ry'imiterere y'umuraba: Mu gihe cy'umutwaro umwe, urusaku rw'umuraba w'amashanyarazi wa mbere rwageze kuri 240mV. Nyuma yo gusimbuza capacitors za YMIN MPS, urusaku rwagabanutseho kugeza kuri 60mV. Ishusho y'umuraba wa oscilloscope igaragaza neza ko imiterere y'umuraba wa voltage yabaye nziza kandi ihamye.
Ikizamini cyo kwiyongera k'ubushyuhe: Mu gihe cy'umuvuduko wuzuye w'amazi (hafi 3A), ubushyuhe bw'ubuso bwa capacitors zisanzwe bushobora kugera kuri dogere selisiyusi zirenga 95, mu gihe ubushyuhe bw'ubuso bwa capacitors za YMIN MPS ari hafi dogere selisiyusi 70 gusa, kugabanuka k'ubushyuhe kuri dogere selisiyusi zirenga 25. Ikizamini cyo kwihutisha ubuzima: Ku bushyuhe bwa dogere selisiyusi 105 n'umuvuduko w'amazi, nyuma y'amasaha 2000, igipimo cyo kugumana ubushobozi cyageze kuri >95%, kirenze cyane urugero rw'inganda.
- Imiterere y'ikoreshwa n'ibyitegererezo by'ikoreshwa - YMIN MPS Series 470μF 2.5V (Ingano: 7.3 * 4.3 * 1.9mm). ESR yabo iri hasi cyane (<3mΩ), amashanyarazi menshi, hamwe n'ubushyuhe bwinshi bwo gukora (105°C) bituma iba ishingiro ryizewe ry'ibishushanyo mbonera by'amashanyarazi mu bikoresho by'itumanaho byo ku rwego rwo hejuru, seriveri, sisitemu zo kubika, na motherboards zo mu nganda.
Umwanzuro
Ku bakora ibikoresho biharanira kwizerwa cyane, gukuraho ingufu z'amashanyarazi ntibikiri ikibazo cyo guhitamo agaciro gakwiye k'ubushobozi; bisaba kwitabwaho cyane ku bipimo bihindagurika nka ESR ya capacitor, umuyoboro wa ripple, n'ubudahangarwa bw'igihe kirekire. Capacitors za YMIN MPS, binyuze mu ikoranabuhanga rigezweho ry'imiterere n'ibikoresho, ziha injeniyeri igikoresho gikomeye cyo guhangana n'ibibazo by'urusaku rw'amashanyarazi. Twizeye ko iri sesengura ryimbitse rya tekiniki rizaguha ubumenyi. Ku bibazo byo gukoresha capacitor, reba YMIN.
