Inqaku eliphambili lePCIM
IShanghai, nge-25 kaSeptemba, ngo-2025—Ngentsimbi ye-11:40 AM namhlanje, kwi-PCIM Asia 2025 Technology Forum eHolo N4 yeShanghai New International Expo Center, uMnu. Zhang Qingtao, uSekela Mongameli weShanghai YMIN Electronics Co., Ltd., unikele intetho ephambili enesihloko esithi “Izicelo ezintsha zeeCapacitors kwiZisombululo zeSemiconductor zeSizukulwana sesithathu.”
Le ntetho igxile kwimingeni emitsha ebangelwe ziiteknoloji ze-semiconductor zesizukulwana sesithathu ezifana ne-silicon carbide (SiC) kunye ne-gallium nitride (GaN) kwii-capacitors phantsi kweemeko zokusebenza ezinzima ezifana ne-frequency ephezulu, i-voltage ephezulu, kunye nobushushu obuphezulu. Le ntetho yazisa ngokucwangcisiweyo iimpumelelo zobuchwepheshe bee-capacitors ze-YMIN kunye nemizekelo esebenzayo ekufezekiseni uxinano oluphezulu lwe-capacitance, i-ESR ephantsi, ubomi obude, kunye nokuthembeka okuphezulu.
Amanqaku aphambili
Ngokwamkelwa ngokukhawuleza kwezixhobo zeSiC kunye neGaN kwizithuthi ezintsha zamandla, indawo yokugcina amandla ye-photovoltaic, iiseva ze-AI, izixhobo zamandla zoshishino, kunye nezinye iindawo, iimfuno zokusebenza zokuxhasa ii-capacitors ziya ziba nzima ngakumbi. Ii-capacitors azisekho nje iindima zokuxhasa; ngoku "ziinjini" ezibalulekileyo ezimisela uzinzo, ukusebenza kakuhle, kunye nobude bexesha lenkqubo. Ngokusebenzisa ubuchule bezinto, ukulungiswa kwesakhiwo, kunye nokuphuculwa kwenkqubo, i-YMIN ifikelele kuphuculo olupheleleyo kwii-capacitors kuzo zonke iinkalo ezine: umthamo, umthamo, ubushushu, kunye nokuthembeka. Oku kuye kwabaluleka kakhulu ekuphunyezweni ngokufanelekileyo kwezicelo ze-semiconductor zesizukulwana sesithathu.
