Lesi sihloko sethula ukusetshenziswa kwe-SiC MOS

Njengento ebalulekile eyisisekelo ekuthuthukisweni kwemboni ye-semiconductor yesizukulwane sesithathu, i-silicon carbide MOSFET inemvamisa yokushintsha ephezulu kanye nezinga lokushisa lokusebenzisa, elinganciphisa usayizi wezingxenye ezinjengama-inductors, ama-capacitor, izihlungi kanye nama-transformer, ukuthuthukisa ukusebenza kahle kokuguqulwa kwamandla kagesi. isistimu, futhi yehlise izidingo zokulahla ukushisa zomjikelezo wokushisa.Ezinhlelweni zamandla kagesi, ukusetshenziswa kwamadivayisi e-silicon carbide MOSFET esikhundleni semishini ye-silicon ye-IGBT yendabuko kungafinyelela ukushintsha okuphansi nokulahlekelwa, kuyilapho kunomthamo ophezulu wokuvinjwa kwamandla kanye nomthamo we-avalanche, kuthuthukisa kakhulu ukusebenza kahle kwesistimu kanye nokuminyana kwamandla, ngaleyo ndlela kunciphise izindleko eziphelele uhlelo.

Okokuqala, izinhlelo zokusebenza ezijwayelekile zemboni

Izindawo eziyinhloko zokufaka isicelo se-silicon carbide MOSFET zifaka: imojula yamandla enqwaba yokushaja, i-photovoltaic inverter, iyunithi yokugcina ukukhanya, isimo somoya semoto yamandla entsha, imoto yamandla entsha i-OBC, ukunikezwa kwamandla embonini, i-motor drive, njll.

1. Imoduli yamandla enqwaba yokushaja

Ngokuvela kweplatifomu engu-800V yezimoto ezintsha ezisebenza ngamandla, imojula yokushaja ejwayelekile isithuthukile ukusuka kweyangaphambilini engu-15, 20kW ukuya ku-30, 40kW, nebanga eliphumayo lika-voltage elingu-300VD-1000VDC, futhi linomsebenzi wokushaja ngezindlela ezimbili ukuhlangabezana. izidingo zobuchwepheshe ze-V2G/V2H.

2. I-Photovoltaic inverter

Ngaphansi kokuthuthukiswa okunamandla kwamandla avuselelekayo emhlabeni wonke, imboni ye-photovoltaic iye yanda ngokushesha, futhi imakethe ye-photovoltaic inverter iyonke ibonise umkhuba wokuthuthuka okusheshayo.

3. Umshini wokugcina obonakalayo

Iyunithi yokugcina i-optical isebenzisa ubuchwepheshe bokulawula amandla kagesi ukuze kuzuzwe ukudluliswa kwamandla ngokulawula okuhlakaniphile, ukuxhumanisa ukulawulwa kwe-photovoltaic namabhethri okugcina amandla, ukushintshashintsha kwamandla abushelelezi, namandla kagesi e-AC aphumayo ahlangabezana nezidingo ezijwayelekile zokuhlinzeka amandla kumthwalo ngokusebenzisa isiguquli sokugcina amandla. ubuchwepheshe, ukuhlangabezana nesicelo esinezimo eziningi ohlangothini lwabasebenzisi, futhi isetshenziswa kakhulu eziteshini zamandla ze-photovoltaic ezingaphandle kwegridi, izinsiza zamandla eziyisipele ezisabalalisiwe, iziteshi zamandla okugcina amandla nezinye izikhathi.

4. I-air conditioning yemoto yamandla amasha

Ngokukhuphuka kwesiteji se-800V ezimotweni zamandla amasha, i-SiC MOS isibe yisinqumo sokuqala emakethe ngezinzuzo zayo zokucindezela okuphezulu nokusebenza kahle okuphezulu, usayizi wephakheji ye-chip encane nokunye.

5. High Power OBC

Ukusetshenziswa kwemvamisa yokushintsha ephezulu ye-SiC MOS kumjikelezo we-OBC wezigaba ezintathu kunganciphisa ivolumu nesisindo sezingxenye kazibuthe, kuthuthukise ukusebenza kahle kanye nokuminyana kwamandla, kuyilapho i-voltage yebhasi yesistimu ephezulu yehlisa kakhulu inani lamadivayisi wamandla, kusiza ukwakheka kwesekethe, futhi kuthuthukisa ukwethembeka.

6. Ukunikezwa kukagesi kwezimboni

Ukunikezwa kwamandla ezimbonini kusetshenziswa kakhulu njengokuphakelwa kwamandla ezokwelapha, ugesi we-laser, umshini wokushisela inverter, ugesi onamandla we-DC-DC, ithrekhi kagandaganda, njll., idinga i-voltage ephezulu, imvamisa ephezulu, izimo zohlelo lokusebenza olusebenza kahle kakhulu.
