I-PCIM Keynote
IShanghai, mhla zingama-25 kuMandulo 2025—Ngo-11:40 ekuseni namuhla, e-PCIM Asia 2025 Technology Forum eHholo N4 leShanghai New International Expo Center, uMnu. Zhang Qingtao, iPhini likaMongameli weShanghai YMIN Electronics Co., Ltd., wethule inkulumo eyinhloko enesihloko esithi “Izicelo Ezintsha Zama-Capacitors Ezixazululweni Ezintsha Ze-Third-Genuine Semiconductor.”
Inkulumo igxile ezinseleleni ezintsha ezibangelwa ubuchwepheshe be-semiconductor besizukulwane sesithathu njenge-silicon carbide (SiC) kanye ne-gallium nitride (GaN) yama-capacitor ngaphansi kwezimo zokusebenza ezimbi kakhulu njengemvamisa ephezulu, i-voltage ephezulu, kanye nokushisa okuphezulu. Inkulumo yethule ngokuhlelekile impumelelo yezobuchwepheshe yama-capacitor e-YMIN kanye nezibonelo ezisebenzayo ekufinyeleleni ubuningi be-capacitance ephezulu, i-ESR ephansi, impilo ende, kanye nokuthembeka okuphezulu.
Amaphuzu Ayinhloko
Ngokwamukelwa okusheshayo kwamadivayisi e-SiC ne-GaN ezimotweni ezintsha zamandla, isitoreji samandla se-photovoltaic, amaseva e-AI, izinsiza zamandla ezimboni, kanye neminye imikhakha, izidingo zokusebenza zama-capacitor asekelayo ziya ngokuya ziba nzima kakhulu. Ama-capacitor awaseyona nje imisebenzi yokusekela; manje aseyi-"injini" ebalulekile enquma ukuzinza, ukusebenza kahle, kanye nobude besikhathi sohlelo. Ngokusungula izinto ezintsha, ukwenza ngcono isakhiwo, kanye nokuthuthukiswa kwenqubo, i-YMIN ifinyelele ukuthuthuka okuphelele kuma-capacitor kuzo zonke izilinganiso ezine: ivolumu, umthamo, izinga lokushisa, kanye nokuthembeka. Lokhu kube yinto ebalulekile ekusetshenzisweni kahle kwezinhlelo zokusebenza ze-semiconductor zesizukulwane sesithathu.
