Ngophuhliso lwamaxesha, ukutshaja okukhawulezayo kweefowuni eziphathwayo kunye neencwadana zamanqaku kuye kwaduma, kwaye amandla okutshaja okukhawulezayo amakhulu eewatts azise iimfuno eziphezulu zeetshaja. Ngo-2021, umgangatho wokutshaja okhawulezayo we-USB PD3.1 uya kuzisa uhlaziyo lwamva nje. Umgangatho omtsha we-USB PD3.1 wokutshaja ngokukhawuleza uya kuxhasa ukuphuma kwe-voltage ukuya kwi-48V, kwaye amandla okutshaja aya kwandiswa ngaxeshanye ukuya kwi-240W. Itekhnoloji yokutshaja ngokukhawuleza iyaqhubeka nokuphuhlisa ngokukhawuleza. Phakathi kwabo, u-Anker, inkampani ehamba phambili ye-e-commerce kwishishini lokutshaja ngokukhawuleza, liya kusungula itshaja ye-150W yosapho lwe-GaN ngo-2022, ukuzisa i-GaN yokutshaja ngokukhawuleza kwelinye inqanaba.
1.Ukutshaja ngokukhawuleza kwe-Dinghaishen inaliti-capacitor
Kuphando kunye nophuhliso lwetshaja, i-capacitor ibaluleke kakhulu. I-capacitor ehambelanayo idlala indima yokucoca kwitshaja, kwaye ithatha impembelelo yangoku ukuqinisekisa ukuba isixhobo asiyi konakala ngenxa yempembelelo. Kwangaxeshanye, ngenxa yobuncinci beetshaja ze-GaN kwimarike, kukho ingxaki yokunyuka kwamaqondo obushushu aphezulu, kwaye ii-capacitors ezinobuxhakaxhaka bokumelana nobushushu ziyafuneka ukuba zisebenzisane, ukuze kuphunyezwe injongo yokwandisa ubomi benkonzo. yetshaja. Okwangoku, isizukulwana esitsha sokutshaja okukhawulezayo sineempawu zamandla aphezulu, ujongano oluninzi, kunye nobukhulu obuncinci, kunye neemfuno zamacandelo angaphakathi e-elektroniki nazo ziya zinyuka ngokunyuka.
I-2.Ymin entsha ye-high-voltage ukumelana ne-ultra-encinci ye-KCM uthotho olukhokela indlela
Ngamandla akhulayo okutshaja okukhawulezayo, i-Ymin iphuhlise kwaye yavelisa uthotho lwe-KCM ye-lead aluminium electrolytic capacitors enevoltage ephezulu yokumelana kunye ne-ultra-encinci yevolumu ngokwesiseko sothotho olukhoyo lwe-KCX lweemveliso zokutshaja ngokukhawuleza. Iimveliso zigubungela ububanzi ukusuka kwi-8 ukuya kwi-18 ukuhlangabezana neemfuno ezahlukeneyo zokutshaja ngokukhawuleza. Ngokukodwa kwiimveliso zokutshaja ezikhawulezayo ezinamandla angaphezu kwe-120W, sibonelela ngeemveliso ze-capacitor eziphezulu ze-voltage ezinobubanzi obuyi-16 ~ 18mm kunye noluhlu lwe-voltage ye-420V ~ 450V ukuqinisekisa ukusebenza kakuhle kokutshaja kunye nokuthembeka.
Ukongezelela, kwimeko yomthamo olinganiselweyo, uchungechunge lwe-KCM lunokuthatha ngokupheleleyo ukuphazamiseka kwe-EMI kumgca phantsi kweemeko zokusebenza zokushisa okuphezulu, ukuphindaphinda okuphezulu kunye namandla aphezulu ngenxa ye-ultra-high-high density kunye ne-ultra-low ESR, ngaloo ndlela kuphuculwe amandla omgangatho wokuguqulwa komatshini wonke.
I-KCM ineempawu zomthamo omncinci, amandla ombane aphezulu okumelana, kunye nobuninzi bomthamo ophezulu. Kwangaxeshanye, ithathela ingqalelo iingenelo zokusebenza ezifana nokumelana nobushushu obuphezulu, ubomi obude, ukuxhathisa ukubetha kombane, ukuvuza okuphantsi kwangoku, ukuxhaphaka okuphezulu kunye nokuxhathisa okuphantsi, kunye nokuxhathisa okukhulu kwe-ripple. Isebenzisa amalungelo awodwa omenzi wechiza aqolileyo Inkqubo yeteknoloji, isebenzisa izinto ezintsha, ukuqhawula imiqobo yobugcisa be-capacitance, ukufezekisa ukuhambelana nokuthembeka. Xa kuthelekiswa nemveliso ye-capacitor ekhawulezayo yokutshaja kwishishini, phantsi kwengcaciso efanayo, uthotho lwe-Ymin KCM lungaphezulu kwama-20% ngaphantsi kunobude beshishini, kwaye imveliso egqityiweyo ukumelana nombane yi-30 ~ 40V ephezulu. Inika isiqinisekiso esilungileyo sokusebenza kwexesha elide elizinzileyo le-capacitor. Okwangoku, uthotho lwe-KCM luye lwaba ngumgangatho oqhelekileyo wevolumu yeemveliso ze-capacitor zokutshaja ngokukhawuleza, ekhokelela kuphuhliso lwe-GaN USB PD yokutshaja ngokukhawuleza kwe-capacitors.
Okwangoku, iimveliso ze-Ymin zasekhaya ze-capacitor zivunyiwe ngu-Anker, Baseus, Aneng Technology, Damai, Philips, Bulls, Huakesheng, Black Shark, Ji Letang, Jiayu, Jinxiang, Lulian, Lenovo, Nokia, SYNCWIRE, Iimpawu ezininzi ezifana neNetease Zhizao kunye ne-H3C bayamkele, kwaye ukusebenza kwayo okugqwesileyo kwemveliso kuye kwaqatshelwa kakhulu ngabathengi.
