Kupu Matua PCIM
Shanghai, Mahuru 25, 2025—I te 11:40 AM i tēnei rā, i te Huinga Hangarau PCIM Asia 2025 i te Whare N4 o te Shanghai New International Expo Center, i whakapuaki a Mr. Zhang Qingtao, te Tumuaki Tuarua o Shanghai YMIN Electronics Co., Ltd., i tētahi whaikōrero matua ko "Ngā Whakamahinga Auaha o ngā Pūnga i roto i ngā Otinga Ārahi-ā-Iwi Hou o te Tuatoru o ngā Reanga."
I arotahi te whaikōrero ki ngā wero hou e pā ana ki ngā hangarau semiconductor o te whakatupuranga tuatoru pērā i te silicon carbide (SiC) me te gallium nitride (GaN) mō ngā pūnga i raro i ngā āhuatanga mahi tino kino pērā i te auau teitei, te ngaohiko teitei, me te pāmahana teitei. I whakaurua e te whaikōrero ngā whanaketanga hangarau o ngā pūnga YMIN me ngā tauira mahi hei whakatutuki i te kiato capacitance teitei, te ESR iti, te roa o te ora, me te pono teitei.
Ngā Kaupapa Matua
I te tere o te whakamahi i ngā taputapu SiC me GaN i roto i ngā waka hiko hou, te rokiroki hiko photovoltaic, ngā tūmau AI, ngā putunga hiko ahumahi, me ētahi atu mara, kei te kaha haere ngā whakaritenga mahi mō ngā pūnga tautoko. Kāore ngā pūnga e noho hei mahi tautoko noa iho; ko rātou inaianei te "mīhini" nui e whakatau ana i te pumau, te whai huatanga, me te roa o te ora o tētahi pūnaha. Mā te auahatanga rauemi, te arotautanga hanganga, me ngā whakapainga tukanga, kua tutuki i a YMIN ngā whakapainga whānui i roto i ngā pūnga puta noa i ngā taha e whā: te rōrahi, te kaha, te pāmahana, me te pono. Kua noho tēnei hei mea nui mō te whakatinanatanga whai hua o ngā tono semiconductor o te tuatoru o ngā whakatipuranga.
