Abstract: Habitations in remote areas around the world lack basic infrastructure to achieve an efficient supply chain. Over 90% of roads are unpaved and fuel infrastructure is scarce. A solar-powered hybrid airship was conceived to address this problem. It is a buoyant low-altitude aircraft with an electric power train and wing-mounted photovoltaic array. Fully electric operation requires efficient lightweight power electronics to maximize range and payload. A Partial Power Processing (PPP) converter based on the bidirectional Cuk topology is demonstrated for this application. Due to the PPP concept, the converter is rated for only about a quarter of the generated PV power. The rating is optimized based on the battery and photovoltaic array voltage ranges. The experimental prototype uses Silicon Carbide MOSFETS and achieves a system efficiency of up to 99.3%.

Abstract translation: 全球偏远地区的居民缺乏基本的基础设施来实现高效的供应链。 超过90％的道路未铺设，燃料基础设施稀缺。 设想了太阳能混合飞艇来解决这个问题。 它是一架浮力低空的飞机，配有电力驱动系统和机翼式光伏阵列。 全电动操作需要高效的轻量级电力电子设备，以最大限度地扩大范围和有效载荷。 基于双向Cuk拓扑的部分功率处理（PPP）转换器被证明适用于此应用。 由于PPP概念，转换器的光伏功率只有大约四分之一。 该等级基于电池和光伏阵列电压范围进行优化。 实验原型使用碳化硅MOSFET，实现高达99.3％的系统效率。
