Njengoba izimoto ezintsha zamandla zisheshisa ukuthuthuka kwazo ekushajeni okusheshayo okunamandla aphezulu, ukushaja nokukhipha amandla okuya ezindaweni ezimbili, kanye nokuhlanganiswa okuphezulu, ubuchwepheshe be-OBC obusebhodini buthuthuka - uhlelo lukagesi olunamandla aphezulu lwe-800V luthuthukela ohlelweni lwe-1200V, kanti ukwakheka kwepulatifomu enamandla aphezulu kuba yisisekelo sokushaja okusheshayo.
01 Iyiphi indima ebalulekile edlalwa yi-capacitor ku-OBC esebhodini?
Kuhlelo lwebhethri olunamandla aphezulu, i-capacitor “iyisikhungo sokugcina amandla kanye nokuhlunga” se-OBC&DCDC, futhi ukusebenza kwayo kunquma ngqo ukusebenza kahle, ubuningi bamandla kanye nokuthembeka kohlelo – kungakhathaliseki ukuthi kungumthelela osheshayo wepulatifomu enamandla aphezulu, ukuguquguquka kwamandla aphezulu, noma izimo zokusebenza eziyinkimbinkimbi zokugeleza kwamandla okuqondiswa kwezinhlangothi ezimbili, i-capacitor iyadingeka ukuze igcine ukusebenza okuzinzile ngaphansi kwezindawo ezinamandla aphezulu, imvamisa ephezulu, kanye nokushisa okuphezulu. Ngakho-ke, ukukhethwa kwama-capacitor anamandla aphezulu kanye nokuqina kwamandla aphezulu kuyisici esibalulekile ekunqumeni ukusebenza kwe-OBC esebhodini.
02 Yiziphi izinzuzo zokusebenzisa ama-capacitor e-YMIN?
Ukuze kuhlangatshezwane nezidingo eziqinile ze-OBC&DCDC ngaphansi kwezinhlelo ze-high-voltage zama-capacitor ukuze amelane ne-voltage ephezulu, usayizi omncane, impilo ende, kanye nomsinga we-ripple ephezulu, i-YMIN yethule i-matrix yomkhiqizo we-capacitor osebenza kahle kakhulu ukuze kunikezwe amandla uhlelo lwe-OBC&DCDC lwezimoto ezintsha zamandla.
01I-capacitor ye-aluminium electrolytic yohlobo lophondo oluwuketshezi: "isivikelo esiqinisa amandla kagesi" sezimo ezinamandla aphezulu
· I-voltage ekwazi ukumelana nokushisa okuphezulu: Ukuphendula izinselele zokushintshashintsha kwe-voltage kanye nokuphakama kwe-voltage okuvame ukuhlangana nakho ku-OBC, i-CW3H series horn capacitor inomklamo we-voltage margin owanele ukunikeza ukwesekwa kwe-voltage eqinile kanye nokuvikelwa kwe-overvoltage. Idlula ezivivinyweni ezinzima zokuguga kwe-voltage ephezulu kanye nokuqina komthwalo ogcwele ngaphambi kokushiya ifektri ukuqinisekisa ukuzinza kwayo kwesikhathi eside kanye nokuthembeka okuphezulu kuzinhlelo zokusebenza ze-OBC.
· Ukumelana nogesi ophezulu we-ripple current: Uma i-OBC isebenza, ugesi we-surge ukhiqizwa ngenxa yokuguqulwa kwamandla njalo. Uma i-capacitor ye-aluminium electrolytic capacitor yohlobo lwe-liquid horn-type isetshenziswa nge-ripple current ephindwe ka-1.3, ukunyuka kwezinga lokushisa kuhlala kuzinzile futhi ukusebenza komkhiqizo kuzinzile.
· Ubuningi bomthamo ophezulu: Inqubo ekhethekile yokugoqa i-riveting ithuthukisa ngempumelelo ubuningi bamandla. Umthamo uphakeme ngo-20% kunemboni ngevolumu efanayo. Ngomthamo ofanayo we-voltage kanye nomthamo, inkampani yethu incane ngobukhulu, isindisa isikhala sokufaka futhi ihlangabezana nokunciphisa komshini wonke.
02I-capacitor ye-aluminium electrolytic ehlanganisiwe yoketshezi: "Ukuphumelela kahle" ekushiseni okuphezulu kanye nendawo encane
Uchungechunge lwe-LKD lwe-aluminium electrolytic capacitor oluyi-plug-in lungashintshwa ukuze luhambisane nesisombululo esingenakusebenzisa ama-capacitor e-liquid horn ngenxa yokulinganiselwa kwevolumu. Luyisinqumo esifanele sokuhlunga okusebenzayo kakhulu kanye nezidingo zokugcina amandla ezithembekile ze-OBC efakwe emotweni ezindaweni ezinama-voltage aphezulu, ama-frequency aphezulu kanye nezimo ezinzima.
· Ukumelana nokushisa okuphezulu: Ukufinyelela izinga lokushisa lokusebenza elingu-105℃ ephaketheni elincane, elidlula kakhulu ama-capacitor ajwayelekile anokumelana nokushisa okungu-85℃, okunikeza isivikelo esithembekile ezindaweni zokusetshenziswa ezishisa kakhulu.
· Ubuningi be-capacitance ephezulu: Ngaphansi kwe-voltage efanayo, umthamo ofanayo kanye nemininingwane efanayo, ububanzi nokuphakama kochungechunge lwe-LKD kuncane ngo-20% kunemikhiqizo yezimpondo, futhi ukuphakama kungaba kuncane ngo-40%.
· Ukusebenza kahle kakhulu kukagesi kanye nokuvala: Ngenxa yomklamo wokumelana nokushisa okuphezulu, i-ESR incishisiwe kakhulu, futhi inamandla okumelana namanje aqinile. Izinto zokuvala ezihlukile kanye nobuchwepheshe benza ukungabi nomoya kwe-LKD kube ngcono kune-capacitor ye-horn, kuyilapho kwandisa ngempumelelo impilo yesevisi, engahlangabezana nezidingo zamahora angu-105℃ angu-12000.
03 I-capacitor ehlanganisiwe eqinile: “ibhuloho elihamba ngezindlela ezimbili” phakathi kokusebenza kahle okuphezulu nokuqina
· Ubuningi be-capacitance ephezulu: Uma kuqhathaniswa nama-capacitor anomthamo ofanayo emakethe, i-capacitance yeAma-capacitor e-hybrid e-YMIN aqinile-amanziikhuphuka ngaphezu kuka-30%, futhi inani le-capacitance lizinzile ngaphakathi kobubanzi obungu-±5% ebangeni lokushisa elibanzi. Ngemva kokusebenza isikhathi eside, inani le-capacitance lizinzile ngaphezu kuka-90%.
· Umsinga wokuvuza ophansi kakhulu kanye ne-ESR ephansi: Umsinga wokuvuza ungalawulwa ngaphakathi kwe-20μA, kanti i-ESR ingalawulwa ngaphakathi kwe-8mΩ, futhi ukuvumelana kwalokhu okubili kuhle. Ngisho nangemva kwenqubo yokugoqa kabusha kwe-soldering engu-260℃ yokushisa okuphezulu, i-ESR kanye nomsinga wokuvuza zihlala zizinzile.
04 Ama-capacitor efilimu: “isithiyo sokuphepha” sokuphila isikhathi eside nokuthembeka okuphezulu
Uma kuqhathaniswa nama-capacitor e-electrolytic, izinzuzo zokusebenza kwama-capacitor efilimu zibonakala ku-voltage ephezulu yokumelana, i-ESR ephansi, i-non-polarity, ukusebenza okuzinzile, kanye nokuphila isikhathi eside, okwenza ukwakheka kohlelo lokusebenza kube lula, ukumelana nokugeleza okukhulu, futhi kuthembeke kakhulu ezindaweni ezinzima.
· I-voltage yokumelana ephezulu kakhulu: ukubekezelela i-voltage ephezulu engaphezu kuka-1200V, asikho isidingo sokuxhumeka ochungechungeni, futhi ingamelana ne-voltage yokusebenza elinganisiwe izikhathi eziyi-1.5.
· Amandla e-Super ripple: Ukubekezelela i-ripple okungu-3μF/A kungaphezu kokuphindwe ka-50 kune-capacitor ye-electrolytic yendabuko.
· Isiqinisekiso sokuphila komjikelezo wokuphila ogcwele: amahora angaphezu kuka-100,000 okuphila kwesevisi, uhlobo olomile kanye nesikhathi sokuphila esingenashelufu. Ngaphansi kwezimo ezifanayo zokusebenzisa,ama-capacitor efilimubangagcina ukusebenza kwabo isikhathi eside.
Esikhathini esizayo, i-YMIN izoqhubeka nokuphenya ngokujulile ubuchwepheshe be-capacitor obunamandla aphezulu kanye nobuchwepheshe obuhlanganisiwe ukuze inikeze amandla asebenza kahle futhi athembekile ezinhlelweni ze-OBC&DCDC zezimoto ezintsha zamandla!
