Ukuhlakaza Ama-Capacitor Aqinile e-YMIN Aphansi e-ESR: Kusukela Ezinzuzweni Zepharamitha Kuya Ekusebenzeni Kwangempela, Ungawupholisa Kanjani Futhi Uthuthukise Ukusebenza Kahle Kumklamo Wokunikezwa Kwamandla?

Isingeniso

Onjiniyela abathandekayo bokuhlinzeka ngogesi, wake wakhathazwa yi-ripple ephezulu njalo kanye nama-capacitor ashisa kakhulu lapho ulungisa ama-prototypes? Ikakhulukazi ekufuneni kwanamuhla amandla aphezulu, i-ESR kanye namakhono wamanje we-ripple wama-capacitor abe yizithiyo ezingabonakali ezinquma impumelelo noma ukwehluleka komklamo. Lesi sihloko sizothatha uchungechunge lwe-VPX/VPT lwe-YMIN njengesibonelo sokuhlaziywa kobuchwepheshe okujulile, okubonisa ukuthi luxazulula kanjani la maphuzu obuhlungu ngedatha eqondile.

Isixazululo kanye nezinzuzo ze-YMIN

Uma sithatha ishaja esheshayo ye-65W 2C2A GaN njengesibonelo, idinga ukusingatha amaza okushintsha afinyelela kumakhulu amaningana e-kHz endaweni evalekile. Uma kusetshenziswa ama-capacitor aqinile ajwayelekile (i-ESR cishe i-40mΩ), ukulahlekelwa kwawo kumaza aphezulu akufanele kuthathwe kancane. Sibonile ukuthi ngaphansi kokukhishwa komthwalo ogcwele, izinga lokushisa eliyinhloko lama-capacitor anjalo lingadlula u-85℃, okungagcini nje ngokubeka izingozi zokuphepha kokushisa kodwa futhi okubangela ukubola kwe-capacitance kanye nokwanda kwe-ESR ngenxa yokushisa okuphezulu, okuphakamisa imibuzo mayelana nokuthembeka kwesikhathi eside.

Inkinga eyinhloko iku-ESR. Ukulahlekelwa amandla P_loss = I_rms² × ESR. Lapho imvamisa yokushintsha ikhuphuka iye ku-100kHz, i-capacitive reactance (Xc) iyancipha kakhulu, futhi i-ESR iba yingxenye eyinhloko ye-impedance. Uma kuthathwa i-capacitor ene-ESR engu-40mΩ ephethe ugesi we-2A njengesibonelo, ukulahlekelwa kwayo yiseli elilodwa kuphakeme njengo-0.16W. Esikhaleni esincane, lokhu kushisa kunzima kakhulu ukukuchitha.Isixazululo sika-YMINkunciphisa i-ESR ibe ngu-20mΩ, kwehlisa ukulahlekelwa kube ngu-0.08W ngaphansi kwezimo ezifanayo, kunciphisa ngokuqondile ukukhiqizwa kokushisa ngesigamu futhi kuxazulule ngokuyisisekelo inkinga yokwenyuka kwezinga lokushisa.

- Isixazululo se-YMIN kanye nezinzuzo zenqubo: Ukuqamba Okubili Kwezinto Ezisetshenziswayo Nesakhiwo -

I-ESR ephansi ye-YMIN ayiyona ingozi, kodwa umphumela wobunjiniyela obuhlelekile:

Ukusungula Izinto Ezintsha Nge-Electrolyte: Kusetshenziswa i-polymer ene-patent high-conductivity polymer, i-ionic conductivity ikhuliswa ngaphezu kuka-30%, okuqinisekisa ukuthi i-ion migration impedance iphansi kakhulu kuma-frequency aphezulu.

Ukuthuthukiswa Kwe-Anode Foil: Ngokusebenzisa i-electrochemical etching, kwakheka isakhiwo esifana ne-tunnel esinezimbobo, okwandisa indawo esebenzayo futhi kuthuthukiswe ukushaja okusheshayo.

Ukwakhiwa kokumelana okuphansi kwangaphakathi: Umklamo okumelana okuphansi kuyo yonke inqubo, kusukela ebhokisini le-aluminium kanye nepulaki yerabha kuya kuma-lead, kunciphisa ukumelana okungadingekile kwezinambuzane kanye nokungena.

- Isitatimende sokuqinisekiswa kwedatha kanye nokuthembeka: Vumela idatha izikhulumele -

Siqhathanise idatha yokuhlola yama-capacitor aqinile e-YMIN VPX 25V 100μF ngaphambi nangemva kokugoqa kabusha. Izinga lokushintsha kwe-ESR lilonke lalilawulwa ngaphakathi kobubanzi obuthile. Ukwenyuka kwenani layo le-ESR kwaba ngu-15.1% kuphela Lokhu kubonisa ukuzinza kokushisa okuhle kakhulu komkhiqizo kanye nokuthembeka kwenqubo, okuqinisekisa ukusebenza okuzinzile kukagesi ngisho nangemva kokuhlanganiswa kwe-SMT.

Izibonelo zezinhlelo zokusebenza zangempela

Isibonelo, ishaja esheshayo ye-Baseus 65W GaN isebenzisaUchungechunge lwe-YMIN VPX,ukushabalalisa ukushisa okuphumelelayo kanye nokukhipha okuzinzile okuhlanganisa kahle la mapharamitha okusebenza kumkhiqizo wokugcina.

Isiphetho

Kwabonjiniyela abaphishekela ukusebenza okuphezulu, inani le-ESR le-capacitor eyodwa lingaba yisici esinqumayo ekusebenzeni kohlelo lonke. I-YMIN Electronics iyaqonda kahle lokhu, kanye nokubekwa kwayo kokuthi “Ngezinhlelo zokusebenza ze-capacitor, phendukela ku-I-YMIN yezixazululo"I-" isekelwe ekhonweni layo lokuxazulula izinkinga zobuchwepheshe eziyinkimbinkimbi. Ngokuhlinzeka ngemikhiqizo ephezulu ene-ESR ephansi njenge-20mΩ, i-YMIN iqhubeka nokufeza umgomo wayo womkhiqizo "wokufaka esikhundleni sabancintisani bamazwe ngamazwe nokuba uphawu oluhamba phambili," ihlinzeka abaklami bamandla basekhaya ngezixazululo zezingxenye ze-chip ezikhiqizwa ngaphakathi ezweni ezisezingeni eliphezulu nezithembekile.
