在全電飛機發展的趨勢下，飛機的電力需求增加，而體積縮小能夠帶來更大的經濟效益，驅使轉換器朝更高的功率密度發展，並且為提高傳輸效益新型飛機採用540V直流傳輸電力。
本論文提出應用於飛機系統之超高頻諧振轉換器，此轉換器使用寬能隙元件與平面變壓器來實現超高切換頻率，最後實作一540V/28V，功率1kW之電路，來驗證本文提之轉換器可行性。

In the development trend of all-electric aircraft, the power demand of the aircraft increases, and the reduction in size can bring greater economic benefits, driving the converter to a higher power density, and to improve transmission efficiency, the new aircraft uses 540V DC to transmit power.
For applied in aircraft, A ultra-high frequency resonant converter proposed in this thesis. This converter uses a wide bandgap element and a planar transformer to achieve ultra-high switching frequency. Finally, a 540V/28V, 1kW circuit is implemented to verify the feasibility of the converter mentioned in this thesis.
