Uyilo oluguquguqukayo oluphezulu, ubunzima obuncinci be-hardware yomqhubi wesango
2021-04-26
Nge-3 kaDisemba, 2020 eMunich, eJamani, i-Infineon Technologies AG ikhuphe i-EiceDRIVER™ X3 eyomeleziweyo ye-analog (1ED34xx) kunye nedijithali (1ED38xx) yomqhubi wesango le-ICs. Ezi zixhobo zibonelela ngemisinga yemveliso eqhelekileyo ye-3, 6 kunye ne-9 A, ubhaqo oluchanekileyo lwe-short-circuit, i-Miller clamp kunye nokuvalwa okuthambileyo. Ukongeza, i-1ED34xx inokubonelela ngexesha lokucoca okuguquguqukayo kunye nexesha elithambileyo lokuphuma kwi-resistor yangaphandle. Ukudibanisa le misebenzi kukhawuleza umjikelo woyilo ngokunciphisa inani lamacandelo angaphandle. I-1ED38xx ibonelela nge-I 2C uqwalaselo lweeparamitha ezininzi. Oku kongeza ukuguquguquka ngakumbi kuyilo, kunciphisa ubunzima be-hardware kunye nokunciphisa ixesha lokuvavanya. Aba baqhubi bamasango bafanelekile kwiidrive zemizi-mveliso, iinkqubo zelanga, izixhobo zombane ezingenakuphazamiseka, iitshaja ze-EV kunye nezinye izicelo zoshishino. I-EiceDRIVER X3 ephuculweyo ye-1ED34xx kunye ne-1ED38xx uthotho lwenzelwe ii-IGBTs kunye ne-SiC kunye ne-Si MOSFETs kwiiphakheji ze-discrete kunye nemodyuli. Imveliso yangoku ukuya kuthi ga kwi-9 A isusa imfuno yamacandelo e-booster yangaphandle. Ukomelela kwe-CMTI okungaphezulu kwe-200 kV/µs kuthintela iipateni zokutshintsha okungalunganga. Zombini uthotho lwabaqhubi besango lunomthamo wombane ogqithisiweyo wemveliso we-40 V kunye nomdlalo wokulibaziseka wokusasaza oqinileyo we-30 ns (ubuninzi), ngaloo ndlela unciphisa ixesha elifileyo. Iinketho ze-I 2C zokuhlengahlengiswa kwe-1ED38xx zibandakanya ukubonwa kwesiphaluka esifutshane, ukucinywa okuthambileyo, phantsi kwe-voltage lockout (UVLO), i-Miller clamp kunye nokuvalwa kwe-thermal. Uluhlu lomqhubi wesango lukwabonelela ngomsebenzi wokuvala ukucima okusekwe yisoftware (TLTOff). I-1ED34xx kunye ne-1ED38xx abaqhubi besango bahlanganiswe kwi-package encinci ye-DSO-16 encinci kunye nomgama we-creepage we-8 mm. Zombini ziyi-UL 1577 eqinisekisiweyo ye-5.7 kV RMS, idityaniswe ne-threshold echanekileyo kunye nexesha, iqinisekisa ukhuseleko oluhle kakhulu lwesicelo. Ziyilelwe ukuba zimelane nemeko yesicelo semizi-mveliso eqatha.
