Likhatelopele tse peli tse kholo lefapheng la -bandgap semiconductors li sa tsoa phatlalatsoa Chaena: 15 kV bidirectional{2}}thibela sesebelisoa sa motlakase sa SiC se entsoeng ke sehlopha sa Dr. Xing Huang se Pinejade, le 10 kV SiC MOSFET e lokollotsoeng ka kopanelo ke Zhanxin Electronics le Univesithi ea Zhejiang.
Liphihlello tsena li tšoaea ho kena ha Chaena sehlopheng sa machaba se itlhommeng pele sa theknoloji ea kV-ea boemo ba SiC 'me ho lebeletsoe hore se tla potlakisa khoebo ea -li-state transformer (SSTs) tse matla, litsi tsa boitsebiso tsa AI, le lisebelisoa tsa matla tse tsosolositsoeng.
Ho Fetola Tekheniki ea Bottleneck ea-Voltage SSTs e Phahameng
E le-sesebediswa se latelang sa motlakase bakeng sa disistimi tsa kamoso tsa eneji, SSTs e tshepisa bokgoni bo hodimo, boholo bo kopaneng, le taolo ya matla e tenyetsehang. Leha ho le joalo, khōlo ea bona ea liindasteri haesale e hatelloa ke mefokolo ea ts'ebetso ea -lisebelisoa tse phahameng tsa motlakase.
Li-IGBT tsa setso tsa silicon ha li khone ho fihlela litlhoko tsa SST bakeng sa motlakase o phahameng, maqhubu a phahameng a ho fetoha, le tahlehelo e tlase. SiC, e nang le matla a silicon ka makhetlo a leshome le tahlehelo e tlase ea switching le conduction, e hlahile e le sesebelisoa se loketseng kV-class high{2}}voltage applications.
Diketso tsa moraorao disebedisweng tsa 10–15 kV SiC di kaonefatsa tshebetso ya SST haholo, di nolofatsa meralo ya seseteme, le ho fokotsa ditjeho{{2}ho rala motheo wa{3}}motlakase wa SST wa phepelo ya motlakase.
15 kV Bidirectional-Ho Thibela SiC Device ho Nolofatsa Mahare-Voltage Topologies
E thehiloe ke Dr. Xing Huang nakong ea mosebetsi oa hae FREEDM Systems Center, North Carolina State University, theSesebelisoa sa 15 kV SiCe shebane le{{0}liqholotso tsa nako e telele- tsa marang-rang a phano ea motlakase.
Lisebelisoa tsa Commercial SiC tse ka tlase ho 3 kV li hloka -litlhophiso tsa maemo a mangata a cascaded H{2}} ho hokela ho 10–35 kV grids. Sena se lebisa ho:
palo e kholo ea lisebelisoa,
ho rarahana ha taolo ho eketsehileng,
ho fokotsa ts'epahalo ea sistimi.
Sesebediswa se secha sa 15 kV-se nang le matla a nnete a ho thibela le 15 kV breakdown voltage{3}}se kgona ho hokahana ka kotloloho le{4}}voltage grid ntle le{5}}maqhubu a mangata, a fokotsa maemo a SST cascading ka 80%.
Moralo o mocha oa bidirectional terminal, o kopantseng le boithuto bo batsi ba-boitšoaro ba potoloho, ho senyeha ha lehloa, le botsofali bo phahameng-le thempereichara e phahameng, bo thusa batho ho tšepahala ka botlalo, 'me bo tšehetsa maemo a thata a kang DC fault isolation le lisebelisoa tsa HVDC.
10 kV SiC MOSFET: Large Chip Area, High Current, le Mass{1}}Production Reading
Ho ISPSD 2025, Zhanxin Electronics le Univesithi ea Zhejiang li hlahisitse 10 kV SiC MOSFET e sebetsanang le liqholotso tse peli tse kholo tsa indasteri: -ho etsa sebaka se seholo le tahlehelo e phahameng-ea motlakase oa motlakase.
Lintlha tsa bohlokoa tsa ts'ebetso:
boholo ba chip: 10 mm × 10 mm, e 'ngoe ea tse kholo ka ho fetisisa tse tlalehiloeng phatlalatsa;
conduction hona joale: ~ 40 A;
breakdown voltage: >12 kV;
ka ho khetheha ka-bohanyetsi (Ron.sp):<120 mΩ·cm², approaching theoretical SiC limits;
e entsoe ka sethala sa 6-SiC se nang le bokhoni ba ho hlahisa ka bongata.
Sesebelisoa se sebelisa-ho kenngoa ha aone ea matla le moralo o moqotetsane oa JFET ho rarolla khoebo-ho tloha lipakeng tsa motlakase o phahameng le o tlase, athe li-terminal tse ntlafalitsoeng li ntlafatsa poelo bakeng sa-lichipisi tse kholo.
Ho nolofalletsa Lintlafatso ho Li-grids tse bohlale, Litsi tsa AI tsa data, le tse nchafalitsoeng
Matla a matla a kV-mohlomong oa SiC a lebelletsoe ho potlakisa tšebeliso ea SST makaleng a mangata:
Li-grids tse bohlale
Li-SST tse sebelisang lisebelisoa tsa SiC tse mahareng-tse matla a motlakase li thusa ho fetoha ha AC-high{1}}frequency–DC, ho ntlafatsa ho tenyetseha ha marang-rang le ho kopanya matla.
AI Data Centers

Matla a-e le 'ngoe a ka fihla ho 1 MW.
PUE e ka theoha ka tlase ho 1.1.
Ho boloka matla ka selemo bakeng sa litsi tsa data tsa hyperscale ho ka fihla ho limilione tse mashome tsa kWh.
Matla a Tsosolositsoeng
Ka lebaka la -lisebelisoa tse holimo:
Li-inverters tsa PV le li-converter tsa moea li ka fokotsa boholo ba filthara ka 50%.
litšenyehelo tsa tsamaiso li fokotseha ka ~ 20%;
Ho tšepahala ho ntlafala tlas'a maemo a thata a tikoloho.
