Thaum Lub Xya Hli 22, 2019, Runau tshaj tawm cov khoom tshiab: 5200V thyristor nrog 5 "chip tau tsim ua tiav thiab npaj los tsim khoom rau cov neeg siv khoom xaj.Cov cuab yeej siv thev naus laus zis tau siv, sib sib zog nqus optimization ntawm impurity diffusion txheej txheem, raug tsim ntawm lithography, nruj kev tiv thaiv technology ntawm mesa qauv, kom lub uniformity, repeatability, thiab controllability impurity diffusion kev ua tau zoo, nrog rau cov zoo heev thaiv cov yam ntxwv.Xws li kev ua haujlwm siab ntawm tam sim no & voltage nce tus nqi yog ua kom ntseeg tau.Nrog rau cov pov thawj pov thawj, qhov nruab nrab rau pem hauv ntej tam sim no tawm tsam 5200V tuaj yeem ncav cuag 4750A nrog qis qis hauv xeev voltage poob, VTM yog 1.5V ntxiv rau IT = 5000A, TJ = 25 ℃.Raws li kev tsim khoom ntiag tug, peb tau ua tiav kev txaus siab nrog kev tshawb fawb ywj pheej thiab kev tsim kho, ua rau engineering thiab kev lag luam kev daws teeb meem ntawm 500KV 3000MW HVDC lub zog xa hluav taws xob ua haujlwm tau hloov pauv thiab ua lag luam.
