M'kupita kwa nthawi, kulipiritsa mwachangu mafoni am'manja ndi zolemba zolembera kwakhala kotchuka, ndipo mphamvu yothamangitsa mwachangu ya ma watts mazana ambiri yabweretsanso zofunika zapamwamba za charger. Mu 2021, mulingo wa USB PD3.1 wothamangitsa mwachangu udzabweretsa kukweza kwaposachedwa. Muyezo watsopano wa USB PD3.1 wothamangitsa mwachangu umathandizira kutulutsa kwamagetsi mpaka 48V, ndipo mphamvu yolipirira idzawonjezeka nthawi imodzi mpaka 240W. Ukadaulo wothamangitsa mwachangu ukupitilira kukula mwachangu. Mwa iwo, Anker, kampani yotsogola ya e-commerce pamakampani othamangitsa mwachangu, adzakhazikitsa chojambulira cha 150W cha banja la GaN mu 2022, ndikubweretsa makampani othamangitsa a GaN pamlingo wina.
1.Kuthamanga mwachangu Dinghaishen singano-capacitor
Pakufufuza ndi chitukuko cha charger, capacitor ndi yofunika kwambiri. Capacitor yofananira imagwira ntchito yosefera mu charger, ndipo imatenga mphamvu yapano kuti zitsimikizire kuti chipangizocho sichidzawonongeka chifukwa champhamvu. Nthawi yomweyo, chifukwa chakuchepa kwa ma charger a GaN pamsika, nthawi zambiri pamakhala vuto la kukwera kwakukulu kwa kutentha, ndipo ma capacitor omwe ali ndi ntchito yabwino kwambiri yolimbana ndi kutentha amafunika kuti agwirizane, kuti akwaniritse cholinga chokulitsa moyo wautumiki. cha charger. Pakalipano, mbadwo watsopano wa kuthamangitsa mofulumira uli ndi makhalidwe amphamvu kwambiri, maulendo angapo, ndi kukula kochepa, ndipo zofunikira pazigawo zamagetsi zamkati zikukweranso.
2.Ymin's KCM's high-voltage resistant ultra-ang'onoting'ono KCM akutsogola
Ndi mphamvu yochulukirachulukira yakuchapira mwachangu, Ymin yapanga ndi kupanga ma KCM angapo a leaded aluminiyamu electrolytic capacitor okhala ndi magetsi olimba kwambiri komanso voliyumu yaying'ono kwambiri pamaziko a KCX mndandanda wazinthu zothamangitsa mwachangu. Zogulitsazo zimaphimba m'mimba mwake kuyambira 8 mpaka 18 kuti zikwaniritse zosowa zosiyanasiyana zolipira mwachangu. Makamaka pamakina othamanga kwambiri omwe ali ndi mphamvu yopitilira 120W, timapereka zida zamagetsi zamagetsi zokhala ndi mainchesi 16 ~ 18mm ndi ma voliyumu osiyanasiyana a 420V ~ 450V kuwonetsetsa kuti kuyendetsa bwino komanso kudalirika.
Kuphatikiza apo, pankhani ya voliyumu yocheperako, mndandanda wa KCM ukhoza kuyamwa kwathunthu kusokoneza kwa EMI ku mzere pansi pamikhalidwe yogwira ntchito ya kutentha kwambiri, ma frequency apamwamba komanso mphamvu yayikulu chifukwa cha kachulukidwe kopitilira muyeso komanso ESR yotsika kwambiri, potero kuwongolera mphamvu ya liwiro lonse makina kutembenuka.
KCM ili ndi mawonekedwe amtundu wocheperako, magetsi olimba kwambiri, komanso kachulukidwe kakang'ono. Panthawi imodzimodziyo, imaganizira ubwino wa ntchito monga kukana kutentha kwapamwamba, moyo wautali, kukana kugunda kwa mphezi, kutsika kwaposachedwa, kutsika kwafupipafupi komanso kutsika kochepa, ndi kukana kwakukulu kwa ripple. Amagwiritsa ntchito matekinoloje okhwima Njira zamakono, pogwiritsa ntchito zipangizo zatsopano, kudutsa zopinga zamakono za luso, kuti akwaniritse kusasinthasintha ndi kudalirika. Poyerekeza ndi zinthu zamakampani zomwe zimachapira mwachangu ma capacitor, molingana ndi zomwezi, mndandanda wa Ymin KCM ndiwotsika kuposa 20% kuposa kutalika kwamakampani, ndipo chomalizidwa chomwe chimatha kupirira magetsi ndi 30 ~ 40V apamwamba. Zimapereka chitsimikizo chabwino cha ntchito yokhazikika ya nthawi yayitali ya capacitor. Pakalipano, mndandanda wa KCM wakhala wofanana ndi voliyumu yamagetsi othamanga kwambiri, zomwe zikutsogolera chitukuko cha GaN USB PD yothamanga mofulumira.
Pakadali pano, zopangira zapakhomo za Ymin zavomerezedwa ndi Anker, Baseus, Aneng Technology, Damai, Philips, Bulls, Huakesheng, Black Shark, Ji Letang, Jiayu, Jinxiang, Lulian, Lenovo, Nokia, SYNCWIRE, Mitundu yambiri monga Nease Zhizao ndi H3C atengera izo, ndi ntchito yake yabwino mankhwala wakhala kwambiri anazindikira ndi makasitomala.
