聚焦氮化镓GaN（gallium nitride）功率器件在提升宇航电源系统高功率密度及高效化方面的潜力，设计了一款集成控制器与驱动器的250 W GaN宇航二次电源样机，并通过Ansys仿真优化高频变压器绕组结构提高输出效率。实验结果表明，该GaN宇航电源峰值输出效率达94%，功率密度约高达12 W/cm²，相较于同等级硅器件电源，效率提升3.8%，功率密度提升2.7倍。此外，单粒子辐射实验验证了GaN器件的抗辐照特性。

Abstract

收起

The potential of gallium nitride (GaN) power devices in enhancing the high power density and efficiency of aerospace power systems is focused on, and a 250 W GaN aerospace secondary power supply prototype with an integrated controller and driver is designed. The high-frequency transformer winding structure is optimized by Ansys simulations to improve the output efficiency. Experimental results show that the peak output efficiency of proposed GaN aerospace power supply reached 94%, and its power density was as high as about 12 W/m². Compared with those of the power supply of the same grade silicon device, its efficiency was 3.8% higher, and its power density was 2.7 times higher. In addition, the results of single-particle radiation experiments verified the anti-irradiation characteristics of GaN devices.
