Avionics is intended to become more and more efficient in terms of energy saving thanks to increased efficiency of embedded system. Today, electricity is presented as the best energy vector compared to hydraulic or pneumatic. This is why current researches aim to focus on power electronic converters in order to meet the future electrical power demand in aircraft networks. In this article, the authors investigate a DC/DC dual active bridge converter which is expected as the best candidate to meet the complex requirements of an aircraft environment, especially the high-voltage dynamics. This persuaded the researchers to study the structure and modulations which are explained and brought face to face with a low-power prototype in order to validate the theoretical assumptions. The next step, is a 3.75 kW demonstrator specification with high integration (2 kW/kg). Semiconductor, magnetics and thermal management selection are presented to reach the specifications. Special care has been provided in an original capacitance calculation method and thermal considerations for heatsink choice. The originality of this work is to build active conversion system to prove it suits to aircraft specifications (high voltage dynamics, overload).

由于嵌入式系统的效率不断提高，航空电子产品有望在节能方面变得越来越高效。如今，与液压或气动相比，电力已成为最佳的能源载体。这就是为什么当前的研究旨在专注于功率电子转换器，以满足飞机网络中未来的电力需求的原因。在本文中，作者研究了一种DC / DC双有源桥式转换器，有望将其作为满足飞机环境复杂需求（尤其是高压动力）的最佳选择。这说服了研究人员研究结构和调制方式，并解释了这些结构和调制方式，并与低功耗原型机面对面，以验证理论假设。下一步是3。高集成度（2 kW / kg）的75 kW演示器规格。提出了半导体，磁性和热管理选择以达到规格。在原始电容计算方法和散热片选择的散热考虑因素方面，已经特别注意。这项工作的独创性是建立主动转换系统，以证明其适合飞机规格（高压动态，过载）。
