基于eGaN® FET的电力转换系统相比于基于硅的替代品，提供了更高的效率、更高的功率密度和更低的总体系统成本。这些优势特性促成了不断增加的功率电子组件生态系统，如门驱动器、控制器和被动组件，这些组件专门用于增强eGaN FET的性能。图1展示了一些eGaN FET的例子。

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.
