在過去的數年間雖然有很多討論關於基於氮化鎵的功率電晶體可以替代普遍使用的矽MOSFET器件,但矽基氮化鎵的功率場效應電晶體可能需要較長的時間才可以在電源轉換領域成為主流器件。目前數個全新應用的出現將有望實現氮化鎵技術所提供的優勢。除了具備商用及高可靠性的條件,氮化鎵器件的獨有特性正在促進全新應用的出現。

Wide-bandgap materials, such as GaN and SiC, are enabling a new generation of power switching devices that switch faster and with fewer losses than the venerable silicon MOSFET, resulting in smaller, more efficient power supplies.

We know Efficient Power Conversion (EPC) has commercialized enhancement-mode GaN-on-Si FETs, or eGaN FETs as EPC calls them, for more than a year now. Concurrently, it has been working with partners to realize dedicated drivers for its eGaN FETs, which offer lower RDS(ON) at higher voltages, lower gate charge, and no reverse recovery loss (QRR)—all these properties from a smaller die size than silicon. In essence, by comparison to silicon MOSFETs, the eGaN FETs offer a dramatic reduction in figures of merit or FOM.

The enhancement mode -normally OFF- GaN technology was explicitly developed to replace power MOSFETs. Says Alex Lidow, EPC’s co-founder and CEO, enhancement mode - rather than depletion mode - is essential for GaN to become a broad-scale silicon power MOSFET replacement.
