Ichi chinyorwa chinosuma mashandisirwo eSiC MOS

Sechinhu chakakosha chekusimudzira indasitiri yerudzi rwechitatu semiconductor, silicon carbide MOSFET ine yakakwira switching frequency uye tembiricha yekushandisa, iyo inogona kuderedza saizi yezvikamu zvakaita semainductors, capacitors, mafirita uye ekushandura, kuvandudza simba rekushandura simba re iyo sisitimu, uye kuderedza zvinodikanwa zvekupisa kupisa kweiyo thermal cycle.Mumagetsi emagetsi masisitimu, kushandiswa kwesilicon carbide MOSFET zvishandiso panzvimbo yechinyakare silicon IGBT zvishandiso zvinogona kuwana yakaderera switching uye-kurasikirwa, uku uine yakakwira blocking voltage uye avalanche simba, zvakanyanya kuvandudza kushanda kwehurongwa uye kuwanda kwesimba, nekudaro kuderedza mutengo wakakwana we hurongwa.

Kutanga, indasitiri yakajairika maapplication

Nzvimbo huru dzekushandisa dzesilicon carbide MOSFET dzinosanganisira: kuchaja murwi wemagetsi module, photovoltaic inverter, optical storage unit, new energy mota air conditioning, mota nyowani OBC, maindasitiri emagetsi, mota drive, nezvimwe.

1. Kuchaja murwi simba module

Nekubuda kwe800V papuratifomu yemotokari itsva dzesimba, iyo mainstream charge module yakagadziridzwa kubva kune yakambopfuura mainstream 15, 20kW kusvika 30, 40kW, ine inobuda voltage renji ye300VD-1000VDC, uye ine nzira mbiri yekuchaja yekusangana. zvinodiwa zvehunyanzvi zveV2G/V2H.

2. Photovoltaic inverter

Pasi pekusimudzira kwakasimba kwesimba rinowanikwazve pasi rose, iyo photovoltaic indasitiri yakawedzera nekukurumidza, uye yakazara photovoltaic inverter musika yakaratidzawo kukurumidza kusimudzira maitiro.

3. Optical kuchengetedza muchina

Iyo optical yekuchengetedza unit inotora magetsi emagetsi ekudzora tekinoroji kuti iwane kufambiswa kwesimba kuburikidza nehungwaru kutonga, kurongedza kutonga kwe photovoltaic uye simba rekuchengetedza mabhatiri, kutsetseka kwemagetsi kushanduka, uye kubuda AC simba remagetsi rinosangana nezvinodiwa zvakajairwa kupa simba kumutoro kuburikidza nekuchengetedza simba rekushandura. tekinoroji, kusangana neakawanda-scenario application kudivi remushandisi, uye inoshandiswa zvakanyanya mu-off-grid photovoltaic magetsi zviteshi, akagoverwa emagetsi ekuchengetedza magetsi, magetsi ekuchengetedza magetsi uye zvimwe zviitiko.

4. New simba motokari yemhepo air conditioning

Nekusimuka kwe800V papuratifomu mumotokari nyowani dzesimba, SiC MOS yave sarudzo yekutanga mumusika ine zvakanakira kudzvanyirira kwakanyanya uye kugona kwakanyanya, diki chip package saizi uye zvichingodaro.

5. High Power OBC

Iko kushandiswa kweiyo yepamusoro switching frequency yeSiC MOS mumatatu-chikamu OBC wedunhu kunogona kuderedza huwandu uye huremu hwemagineti zvikamu, kuvandudza kushanda uye simba remagetsi, nepo yakakwira system bhazi voltage inoderedza zvakanyanya huwandu hwemagetsi emagetsi, inofambisa dhizaini yedunhu, uye inovandudza kuvimbika.

6. Industrial power supply

Maindasitiri emagetsi emagetsi anonyanya kushandiswa mune akadai semagetsi ekurapa, laser magetsi, inverter welding muchina, yakakwirira-simba DC-DC magetsi emagetsi, track tirakita, nezvimwe, inoda yakakwira voltage, yakakwira frequency, yakakwirira-inoshanda mamiriro ekushandisa.
