eGaN® FET 基於的電力轉換系統比基於 Si 的替代方案具有更高的效率、更高的功率密度和更低的整體系統成本。這些優勢特性促進了越來越多的電力電子元件生態系統的出現，例如門驅動器、控制器和被動元件，專門增強eGaN FET的性能。圖1顯示了一些 eGaN FET 的範例。

There are many reasons to increase frequency of power conversion.  Fundamentally, these reasons boil down to size/weight reduction, and cost reduction.  There are several components in the design of a power system that must perform efficiently at the targeted increased switching frequencies.  These include power switches, power switch drivers, controllers, magnetics, and capacitors. Taken collectively, these components represent the high frequency power conversion ecosystem.  Without any of these elements, the benefits of increased frequency cannot be fully realized.
