Ngokuthuthuka kwaleso sikhathi, ukushaja okusheshayo kwamafoni aphathwayo nama-laptop kuye kwaba yinto ethandwayo, futhi amandla okushaja okusheshayo amakhulu ama-watts nawo alethe izidingo eziphakeme zamashaja. Ngo-2021, indinganiso yokushaja okusheshayo ye-USB PD3.1 izothola ukuthuthukiswa kwakamuva, kanti indinganiso entsha yokushaja okusheshayo ye-USB PD3.1 izosekela ukuphuma kwamandla kagesi aphezulu angu-48V, okwandisa amandla okushaja abe ngu-240W ngesikhathi esifanayo. Ubuchwepheshe bokushaja okusheshayo buyaqhubeka nokukhula ngokushesha, kanti i-Anke, inkampani ehamba phambili kwezentengiselwano ze-e-commerce embonini yokushaja okusheshayo, yethule ishaja ephelele yomndeni we-gallium nitride engu-150W ngo-2022, okwenza imboni yokushaja okusheshayo ye-gallium nitride iye kwenye indawo ephakeme.
Ocwaningweni nasekuthuthukisweni kwamashaja, ama-capacitor abalulekile. Ama-capacitor ahambisanayo adlala indima yokuhlunga kushaja, aqinisekisa ukuthi amadivayisi awonakaliswa ngenxa yemithelela yokumunca imisinga ye-impulse. Ngesikhathi esifanayo, amashaja e-gallium nitride emakethe ngokuvamile anenkinga yokwenyuka kwezinga lokushisa eliphezulu ngenxa yobukhulu bawo obuncane, futhi adinga ama-capacitor anokusebenza okuhle kakhulu kokumelana nokushisa ukuthi abambisane, ukuze kufezwe umgomo wokwandisa impilo yesevisi yamashaja. Njengamanje, isizukulwane esisha sokushaja okusheshayo sinezici zamandla aphezulu, izixhumanisi eziningi, kanye nevolumu encane, futhi izidingo zezingxenye ze-elekthronikhi zangaphakathi nazo ziyanda.
Njengoba amandla okushaja okusheshayo ekhula, i-YMIN ithuthukise futhi yakhiqiza uchungechunge lwe-KCMi-capacitor ye-Electrolytic ye-aluminium leadnge-voltage ephezulu yokumelana kanye nevolumu encane kakhulu ngokusekelwe ochungechungeni olukhona lwe-KCX lwemikhiqizo ekhethekile yokushaja okusheshayo. Imikhiqizo imboza ububanzi obusukela ku-8 kuya ku-18 ukuze ihlangabezane nazo zonke izinhlobo zezidingo zokushaja okusheshayo. Ikakhulukazi emikhiqizweni yokushaja ngesivinini esiphezulu enamandla angaphezu kuka-120W, sinikeza imikhiqizo ye-capacitor enamandla aphezulu enobubanzi obungu-16-18, enobubanzi be-voltage obungu-420V-450V, okuqinisekisa ukusebenza kahle kokushaja kanye nokuthembeka.
Ngaphezu kwalokho, uma kunomthamo omncane, uchungechunge lwe-KCM, kanyeukuminyana kwamandla aphezulu kakhulufuthii-ESR ephansi kakhulu,ingamunca ngokuphelele ukuphazamiseka kwe-EMI kusekethe ngaphansi kwezimo zokusebenza ezishisa kakhulu, ezivame kakhulu, nezinamandla aphezulu, ngaleyo ndlela ithuthukise izinga lokuguqulwa kwamandla omshini wonke.
I-KCM inezici zomthamo omncane, ukumelana namandla aphezulu, kanye nobuningi bomthamo ophezulu, kuyilapho icabangela izinzuzo zokusebenza njengokumelana nokushisa okuphezulu, impilo ende, ukumelana nombani, ukuvuza okuphansi, ukumelana okuphansi kwemvamisa ephezulu, kanye nokumelana okukhulu kwe-ripple. Isebenzisa ubuchwepheshe benqubo obuvuthiwe obunelungelo lobunikazi, yamukela izinto ezintsha, futhi idlula ezithiyo zobuchwepheshe be-capacitor ukuze ifinyelele ukuvumelana nokuthembeka. Uma kuqhathaniswa nemikhiqizo ye-capacitor yokushaja okusheshayo embonini, ngaphansi kwemininingwane efanayo, uchungechunge lwe-KCM lwe-YMIN luphansi ngaphezu kuka-20% ngokuphakama kunomkhakha, futhi umkhiqizo oqediwe unokumelana kwamandla kagesi okungu-30-40V okuphezulu. Lokhu kunikeza iziqinisekiso ezinhle zokusebenza okuzinzile kwesikhathi eside kwama-capacitor. Njengamanje, uchungechunge lwe-KCM selube yi-Weather vane ejwayelekile yemikhiqizo ye-capacitor yokushaja okusheshayo, okuholela ekuthuthukisweni kwama-capacitor okushaja okusheshayo e-GaN USB PD.
Njengamanje, imikhiqizo ye-capacitor yasekhaya ye-YMIN isetshenziswe yimikhiqizo eminingi efana ne-Anke, i-Beisi, i-Anneng Technology, i-barley, i-Philips, i-Bull, i-Huakesheng, i-Black Shark, i-Jiletang, i-Jiayu, i-Jinxiang, i-Lvlian, i-Lenovo, i-Nokia, i-SYNCWIRE, i-NetEase Intelligent Manufacturing, kanye ne-Xinhua, futhi ukusebenza kwayo okuhle kakhulu komkhiqizo kuye kwaqashelwa kakhulu ngamakhasimende.
