Gukuraho Capacitors za YMIN zo hasi za ESR Solid: Kuva ku byiza bya Parameter kugeza ku mikorere nyayo, Nigute wa "gutuza no kunoza imikorere" mu gushushanya amashanyarazi?

Intangiriro

Bahanga mu by’amashanyarazi, ese wigeze uhura n’ibibazo byo gushyuha cyane no gushyuha cyane kwa capacitors mu gihe cyo gukosora prototypes? Cyane cyane mu gihe cyo gushakisha imbaraga nyinshi, ESR n’ubushobozi bwa capacitors bwa ripple byabaye inzitizi zitagaragara zigena intsinzi cyangwa gutsindwa kw’igishushanyo. Iyi nkuru izafata urukurikirane rwa YMIN rwa VPX/VPT nk'urugero rw’isesengura ryimbitse rya tekiniki, igaragaza uburyo rukemura izi ngingo z’ingorane hakoreshejwe amakuru afatika.

Igisubizo n'Ibyiza bya YMIN

Dufashe urugero rw'icyuma gisanzwe cya 65W 2C2A GaN gishyushya vuba, kigomba guhangana n'umuvuduko wo guhinduranya wa kHz magana menshi mu mwanya ufunze. Iyo hakoreshejwe capacitors zisanzwe zikomeye (ESR hafi 40mΩ), igihombo cyazo ku muvuduko wo hejuru ntabwo kigomba gusuzugurwa. Twabonye ko iyo umuvuduko wuzuye w'umutwaro, ubushyuhe bw'ibanze bwa capacitors nk'izo bushobora kurenza 85℃, ibyo bikaba bidateza gusa ingaruka mbi ku bushyuhe ahubwo binatera kwangirika kwa capacitors na ESR yiyongera bitewe n'ubushyuhe bwinshi, bigatera kwibaza ku bijyanye no kwizerana igihe kirekire.

Ikibazo nyamukuru kiri muri ESR. Ingufu zigabanuka P_loss = I_rms² × ESR. Iyo frequency yo guhindura izamuka ikagera kuri 100kHz, capacitive reactance (Xc) igabanuka cyane, maze ESR iba igice cy'ingenzi cya impedance. Dufashe capacitor ifite ESR ya 40mΩ itwara umuyoboro wa 2A ripple nk'urugero, igihombo cyayo cy'uturemangingo kamwe kiba hejuru ya 0.16W. Mu mwanya muto, ubu bushyuhe buragoye cyane kubukuraho.Igisubizo cya YMINigabanya ESR kugeza kuri 20mΩ, igabanya igihombo kugeza kuri 0.08W mu bihe bimwe, ikagabanya kabiri mu buryo butaziguye umusaruro w'ubushyuhe kandi igakemura ikibazo cy'izamuka ry'ubushyuhe.

- Ibisubizo bya YMIN n'Ibyiza by'Imikorere: Udushya Dubiri mu Bikoresho n'Imiterere -

ESR iri hasi ya YMIN si impanuka, ahubwo ni umusaruro w'ubuhanga busanzwe:

Udushya mu by'amashanyarazi: Hakoreshejwe polymer ifite ubushobozi bwo gutwara ibintu byinshi, ubwiyongere bw'ingufu za ioni bwiyongeraho hejuru ya 30%, bigatuma habaho impedance nke cyane yo kwimuka kwa ioni ku murongo wo hejuru.

Gutunganya Anode Foil: Binyuze mu gukata amashanyarazi, hakorwa imiterere imeze nk'imyenge y'umuyoboro, bigatuma ubuso burushaho kuba bwiza kandi bikanoza uburyo bwo gutanga amashanyarazi ako kanya.

Imiterere y’imbere idakomeye: Imiterere idakomeye mu gihe cyose cy’igikorwa cyose, kuva ku gasanduku ka aluminiyumu n’agapira k’icyuma kugeza ku byuma bigabanya ubushobozi bwo kurwanya udukoko no gukurura amazi mu buryo butari ngombwa.

- Itangazo ryo kugenzura amakuru no kuyashingiraho: Reka amakuru yivugire -

Twagereranije amakuru y’igerageza rya capacitors zikomeye za YMIN VPX 25V 100μF mbere na nyuma yo kongera gukoresha soldering. Igipimo rusange cy’impinduka za ESR cyagenzurwaga mu rugero runaka. Izamuka ry’agaciro ka ESR ryabaye 15.1% gusa. Ibi bigaragaza ko ubushyuhe buhamye kandi ko inzira zihamye, bigatuma amashanyarazi ahora ahindagurika ndetse na nyuma yo guteranya SMT.

Ingero z'ibikorwa bifatika

Urugero, Baseus 65W GaN fast charger ikoreshaUrukurikirane rwa YMIN VPX,uburyo bwo gukwirakwiza ubushyuhe neza n'umusaruro uhoraho bikubiyemo neza ibi bipimo by'imikorere mu musaruro wa nyuma.

Umwanzuro

Ku bahanga bakurikirana imikorere myiza, agaciro ka ESR ka capacitor imwe gashobora kuba ikintu cy’ingenzi mu mikorere rusange ya sisitemu. YMIN Electronics irabyumva neza, hamwe n’aho iherereye muri "Ku bijyanye n’ikoreshwa rya capacitor, reba kuriYMIN ku bisubizo"ishingiye ku bushobozi bwayo bwo gukemura ibibazo bikomeye bya tekiniki. Mu gutanga ibicuruzwa byo ku rwego rwo hejuru bifite ESR nkeya nka 20mΩ, YMIN ikomeje kugera ku ntego yayo y'ibicuruzwa yo "gusimbuza abanywanyi mpuzamahanga no kuba ikirango gikomeye," iha abashushanya ibikoresho by'amashanyarazi bo mu gihugu ibisubizo byiza kandi byizewe by'ibice bya chip bikorerwa mu gihugu.
