本文详细介绍了一种用于机载风力涡轮机系统的最小重量输入串联输出并联结构双有源桥（DAB）变换器的设计、实现和实验验证。DAB转换器的主要功率部件，特别是桥式电路、主动冷却高频Transformer和电感器以及冷却系统，它们在很大程度上影响了系统的总重量，基于多目标考虑来设计和实现，即，在重量和效率方面。此外，设计包括实现全功能原型的所有必要考虑，即，本发明还考虑辅助电源、在指定的操作范围内对系统的稳定操作的控制以及启动和关闭过程，所述系统还包括输入滤波器。这些考虑表明了系统各部件之间复杂的相互作用，并揭示了一个全面的概念化是必要的，以达到可靠的最小重量设计。实验结果验证了所提出的设计方法，实现了轻量级DAB硬件原型，额定功率为6.25千瓦。原型重量为1.46 kg，即，功率重量比为4.28 kW/kg（1.94 kW/lb），最大满载效率为97.5%。
This paper details the design, implementation, and experimental verification of a minimum weight input series output parallel structured dual active bridge (DAB) converter for an airborne wind turbine system. The main power components of the DAB converter, particularly the bridge circuits, the actively cooled high-frequency transformer and inductor, and the cooling system, which largely contribute to the total system weight, are designed and realized based on multiobjective considerations, i.e., with respect to weight and efficiency. Furthermore, the design includes all necessary considerations to realize a fully functional prototype, i.e., it also considers the auxiliary supply, the control for a stable operation of the system, which also comprises an input filter, over the specified operating range, and the start-up and shut down procedures. These considerations show the complex interactions of the various system parts and reveal that a comprehensive conceptualization is necessary to arrive at a reliable minimum weight design. Experimental results validate the proposed design procedure for a realized lightweight DAB hardware prototype with a rated power of 6.25 kW. The prototype weighs 1.46 kg, i.e., features a power-to-weight ratio of 4.28 kW/kg (1.94 kW/lb), and achieves a maximum full-load efficiency of 97.5%.
