第4代SiC MOSFET

特點

1.改進短路耐受時間，實現業界超低導通電阻

在第4代碳化矽MOSFET中，透過進一步改進羅姆自有的雙溝槽結構，成功地改進主驅逆變器等要求的短路耐受時間為前提，使導通電阻比以往產品降低約40%。實現了碳化矽MOSFET產品的業界超低導通電阻。

2.通過大幅降低寄生電容，實現更低開關損耗

第4代碳化矽MOSFET通過大幅降低柵漏電容（Cgd），成功使開關損耗比以往產品降低約50％。

3.支援15V柵源驅動電壓，使應用產品的設計更容易

在MOSFET中，需要在器件ON時向電晶體的柵極施加一定量的電壓。除了到第3代碳化矽MOSFET為止所支援的18V柵源驅動電壓（Vgs）外，第4代碳化矽MOSFET還支援更容易處理的15V柵源驅動電壓，可與IGBT一起用來設計驅動電路（柵極驅動電路）。

應用範例：主驅逆變器

有助於包括車載逆變器和各種開關電源在內，各種應用產品實現顯著的小型化和更低功耗，比如在用於車載主驅逆變器時，與使用IGBT時相比，效率可以得到顯著提升，主要體現在逆變器的高扭矩和低轉速範圍，從而可使電耗減少6%（按國際標準“WLTC燃料消耗量測試”計算）。
