Njengoba izimoto zamandla amasha zisheshisa ukuvela kwazo ekushajeni okushesha ngamandla, ukushaja okuphindwe kabili nokudedelwa, kanye nokuhlanganiswa okuphezulu, ukuthuthukiswa kobuchwepheshe be-OBC ebhodini - uhlelo lukagesi olunamandla kagesi angu-800V luthuthukela ohlelweni lwe-1200V, kanye nesakhiwo sepulatifomu samandla kagesi aphezulu siba yisisekelo sokushaja ngokushesha.
01 Iyiphi indima ebalulekile edlalwa i-capacitor ku-OBC esebhodini?
Kusistimu yebhethri lamandla kagesi aphezulu, i-capacitor "iyindawo yokugcina amandla kanye nokuhlunga" ye-OBC&DCDC, futhi ukusebenza kwayo kunquma ngokuqondile ukusebenza kahle, ukuminyana kwamandla nokuthembeka kwesistimu - kungakhathaliseki ukuthi umthelela osheshayo weplathifomu yamandla kagesi aphezulu, ukushintshashintsha kwamandla emvamisa ephezulu, noma izimo zokusebenza eziyinkimbinkimbi zokugeleza kwamandla okusebenza okudingekayo, ukugeleza kwamandla okusebenza ngaphansi kokuqondisa. high-voltage, high-frequency, kanye nezindawo ezishisa kakhulu. Ngakho-ke, ukukhethwa kwe-high-voltage resistant kanye ne-high-capacity-density capacitor kuyisici esibalulekile ekunqumeni ukusebenza kwe-OBC ebhodini.
02 Yiziphi izinzuzo zohlelo lokusebenza lwe-YMIN capacitor?
Ukuze ubhekane nezidingo eziqinile ze-OBC&DCDC ngaphansi kwezinhlelo zamandla kagesi aphezulu ukuze ama-capacitor akwazi ukumelana nogesi ophezulu, usayizi omncane, impilo ende, kanye namandla amanje anyakazayo, i-YMIN yethule i-matrix yomkhiqizo we-capacitor esebenza kahle kakhulu ukuze inikeze amandla uhlelo lwe-OBC&DCDC lwezimoto zamandla amasha.
01I-aluminium electrolytic capacitor yophondo oluwuketshezi: "i-voltage stabilizing guard" yezimo zamandla aphezulu
· Amandla kagesi amelana aphezulu: Ekuphenduleni izinselele zokuguquguquka kwamandla kagesi kanye nokunyuka kwamandla kagesi okuvame ukubhekwana nazo ku-OBC, i-CW3H series horn capacitor inomklamo owanele wemajini kagesi ukuze inikeze ukusekela kwamandla kagesi okuqinile kanye nokuvikela ukugcwala ngokweqile. Ibhekana nokuhlolwa okuqinile kokuguga kwe-high-voltage nokuqina komthwalo ogcwele ngaphambi kokushiya ifekthri ukuze kuqinisekiswe ukuzinza kwayo kwesikhathi eside nokwethembeka okuphezulu ezinhlelweni ze-OBC.
· Ukumelana okuphezulu kwe-ripple kwamanje: Uma i-OBC isebenza, amandla akhuphukayo akhiqizwa ngenxa yokuguqulwa kwamandla kaningi. Uma i-aluminium electrolytic capacitor yohlobo lwe-aluminiyamu yophondo oluwuketshezi isetshenziswa izikhathi ezingu-1.3 kunamanje olinganisiwe, izinga lokushisa lihlala lizinzile futhi nokusebenza komkhiqizo kuzinzile.
· Umthamo omkhulu wokuminyana: Inqubo ekhethekile yokuvunguza i-riveting ithuthukisa ngempumelelo ukuminyana kwamandla. Umthamo uphakeme ngo-20% kunemboni ngevolumu efanayo. Ngamandla kagesi afanayo kanye nomthamo, inkampani yethu incane ngosayizi, yonga indawo yokufaka futhi ihlangabezana ne-miniaturization yomshini wonke.
02I-Liquid plug-in aluminium electrolytic capacitor: "Ukuphumelela ngempumelelo" kumazinga okushisa aphezulu kanye nesikhala esihlangene
I-liquid plug-in aluminium electrolytic capacitor LKD series ingashintshwa ukuze ikwazi ukusebenzisa ama-capacitor ophondo oluwuketshezi ngenxa yokulinganiselwa kwevolumu. Kuyinketho ekahle yokuhlunga okusebenza kahle kakhulu kanye nezidingo zokugcina amandla ezinokwethenjelwa ze-OBC egibele imoto ku-high-voltage, imvamisa ephezulu nezimo ezinonya.
· Ukumelana nezinga lokushisa eliphezulu: Ukuzuza izinga lokushisa elisebenzayo elingu-105℃ kuphakheji elihlangene, elidlula kude ama-capacitor avamile anokumelana nezinga lokushisa elingu-85℃, okuhlinzeka ngokuvikeleka okuthembekile kwezindawo zokufaka izicelo ezisezingeni eliphezulu.
· High capacitance density: Ngaphansi kwe-voltage efanayo, umthamo ofanayo kanye nokucaciswa okufanayo, ububanzi nokuphakama kochungechunge lwe-LKD kuncane ngo-20% kunemikhiqizo yezimpondo, futhi ukuphakama kungaba ku-40% kuncane.
· Ukusebenza kahle nokubekwa uphawu kukagesi: Ngenxa yomklamo wokumelana nezinga lokushisa eliphezulu, i-ESR inciphe kakhulu, futhi inamandla okumelana ne-ripple yamanje. Izinto eziyingqayizivele zokuvala nobuchwepheshe zenza i-LKD airtightness iphakame kune-horn capacitor, kuyilapho ilula ngokuphumelelayo impilo yesevisi, engahlangabezana nezidingo zamahora angu-105 ℃ 12000.
03 I-Solid-liquid hybrid capacitor: "ibhuloho lezindlela ezimbili" phakathi kokusebenza kahle okuphezulu nokuzinza
· High capacitance density: Uma kuqhathaniswa nama-capacitor evolumu efanayo emakethe, amandlaI-YMIN solid-liquid hybrid capacitorinyuswe ngaphezu kuka-30%, futhi inani le-capacitance lizinzile ngaphakathi kwebanga elingu-±5% ebangeni elibanzi lokushisa. Ngemuva kokusebenza isikhathi eside, inani le-capacitance lizinzile ngaphezu kuka-90%.
· I-ESR evuzayo ephansi kakhulu nephansi kakhulu: Ukuvuza kwamanje kungalawulwa ngaphakathi kwe-20μA, futhi i-ESR ingalawulwa ngaphakathi kwe-8mΩ, futhi ukuvumelana kwakho kokubili kuhle. Ngisho nangemva kwenqubo yokudayiswa kwe-high-temperature reflow soldering engu-260℃, i-ESR kanye nokuvuza kwamanje kuhlala kuzinzile.
04 Ama-Film capacitor: "isithiyo sokuphepha" sempilo ende nokuthembeka okuphezulu
Uma kuqhathaniswa nama-electrolytic capacitor, izinzuzo zokusebenza zama-capacitor wefilimu zibonakala ku-voltage ephezulu yokumelana, i-ESR ephansi, i-non-polarity, ukusebenza okuzinzile, nempilo ende, okwenza ukwakheka kwesistimu yayo yohlelo lokusebenza kube lula, ukumelana nokugeleza okukhulu, nokwethenjelwa kakhulu ezindaweni ezinokhahlo.
· I-Ultra-high ukumelana ne-voltage: ukubekezelela i-voltage ephezulu engaphezu kuka-1200V, asikho isidingo sokuxhuma kochungechunge, futhi ingamelana izikhathi ezingu-1.5 zevolthi yokusebenza elinganiselwe.
· I-Super ripple capability: Ukubekezelela kwe-ripple okungu-3μF/A kungaphezu kokuphindwe ka-50 kunama-electrolytic capacitor endabuko.
· Isiqinisekiso sempilo yomjikelezo wempilo egcwele: amahora angaphezu kuka-100,000 wempilo yesevisi, uhlobo olomile futhi akukho kuphila kweshalofu. Ngaphansi kwezimo ezifanayo zokusetshenziswa,ifilimu capacitorsbangagcina ukusebenza kwabo isikhathi eside.
Ngokuzayo, i-YMIN izoqhubeka nokujula kubuchwepheshe obunamandla kagesi kanye nokuhlanganiswa kwe-capacitor ukuze inikeze amandla asebenza kahle futhi anokwethenjelwa ezinhlelweni ze-OBC&DCDC zezimoto zamandla amasha!
