Eli nqaku lazisa ukusetyenziswa kwe-SiC MOS

Njengesixhobo esisisiseko esibalulekileyo kuphuhliso lweshishini le-semiconductor yesizukulwana sesithathu, i-silicon carbide MOSFET inesantya esiphezulu sokutshintsha kunye nobushushu bokusebenzisa, obunokunciphisa ubungakanani bezinto ezinje ngee-inductors, ii-capacitors, izihluzi kunye neziguquli, ukuphucula ukusebenza kakuhle kokuguqulwa kwamandla. inkqubo, kunye nokunciphisa iimfuno zokutshatyalaliswa kobushushu kumjikelo we-thermal.Kwiinkqubo zombane we-elektroniki, ukusetyenziswa kwezixhobo ze-silicon carbide MOSFET endaweni yezixhobo ze-silicon ze-IGBT zemveli zinokufikelela ekutshintsheni okuphantsi kunye nelahleko, ngelixa inamandla ombane aphezulu okuthintela kunye nomthamo we-avalanche, iphucula kakhulu ukusebenza kakuhle kwenkqubo kunye noxinzelelo lwamandla, ngaloo ndlela kuncitshiswa iindleko ezibanzi inkqubo.

Okokuqala, ushishino oluqhelekileyo lwezicelo

Iindawo eziphambili zesicelo se-silicon carbide MOSFET ziquka: ukutshaja imodyuli yamandla emfumba, i-photovoltaic inverter, iyunithi yokugcina i-optical, i-air conditioning yemoto entsha, isithuthi samandla esitsha se-OBC, ukunikezelwa kwamandla kwi-industrial, i-motor drive, njl.

1. Ukutshaja imodyuli yamandla emfumba

Ngokuvela kweqonga le-800V lezithuthi zamandla amatsha, imodyuli yokutshaja eqhelekileyo iye yaphuhliswa ukusuka kwi-15, i-20kW ukuya kwi-30, i-40kW, kunye noluhlu lwe-voltage ephumayo ye-300VD-1000VDC, kwaye inomsebenzi wokutshaja ngeendlela ezimbini ukuhlangabezana. iimfuno zobugcisa zeV2G/V2H.

2. I-Photovoltaic inverter

Ngaphantsi kophuhliso olunamandla lwamandla avuselelekayo kwihlabathi, imboni ye-photovoltaic iye yanda ngokukhawuleza, kwaye i-market ye-photovoltaic inverter yonke ibonise uphuhliso olukhawulezayo.

3. Umatshini wokugcinwa kwamehlo

Iyunithi yokugcina i-optical ithatha itekhnoloji yokulawula amandla e-elektroniki ukufezekisa ukuhanjiswa kwamandla ngolawulo olukrelekrele, ukulungelelanisa ulawulo lwe-photovoltaic kunye neebhetri zokugcina amandla, ukuguquguquka kwamandla agudileyo, kunye nokuphuma kwamandla ombane e-AC ahlangabezana neemfuno eziqhelekileyo zokubonelela amandla kumthwalo ngokusebenzisa isiguquli sokugcina amandla. itekhnoloji, ukuhlangabezana nesicelo se-multi-scenario kwicala labasebenzisi, kwaye isetyenziswa ngokubanzi kwizikhululo zamandla ze-photovoltaic ezingaphandle kwegridi, ukuhanjiswa kwamandla okugcina amandla, izikhululo zamandla okugcina amandla kunye nezinye izihlandlo.

4. Umoya omtsha kwinqwelo yamandla

Ngokunyuka kweqonga le-800V kwizithuthi zamandla amatsha, i-SiC MOS ibe yinto yokuqala yokukhetha kwiimarike kunye neenzuzo zayo zoxinzelelo oluphezulu kunye nokusebenza kakuhle, ubungakanani bephakheji encinci ye-chip kunye nokunye.

5. High Power OBC

Ukusetyenziswa kokutshintsha okuphezulu okuphindaphindiweyo kwe-SiC MOS kwisigaba sesithathu sesekethe ye-OBC kunokunciphisa umthamo kunye nobunzima bamacandelo magnetic, ukuphucula ukusebenza kunye noxinano lwamandla, ngelixa i-voltage yebhasi ephezulu inciphisa kakhulu inani lezixhobo zamandla, iququzelele uyilo lwesekethe, kwaye kuphucula ukuthembeka.

6. Ubonelelo lwamandla kwimizi-mveliso

Ubonelelo lwamandla kwimizi-mveliso lusetyenziswa ikakhulu kumandla ombane wezonyango, unikezelo lwamandla ngelaser, umatshini wokuwelda inverter, unikezelo lwamandla aphezulu eDC-DC, umzila wetrektara, njl.
