摘要

本文探讨了低压，大电流DC-DC转换器的各种设计策略，以优化效率，体积和质量，同时通过仅使用现有组件(包括电感和散热器)保持项目的简单和成本效益。针对一个特定的航空应用，研究了拓扑结构对效率和紧凑性的影响。一个2kW的3级FCML模块已开发用于100V至28V DC-DC降压。它依靠对并联的EPC2022 GaN晶体管来显着提高转换器的功率密度。通过计算机仿真比较了两种减少寄生交换环路的路由策略，并进行了实验验证。在原型上的第一次实验结果表明，在12.5kW/L的特定功率下，效率高达98.4%。

Design and efficiency measurement of a sub-unit for a 20kW DC-DC multiphase power converter

This paper explores various design strategies for low-voltage, high current DC-DC converters, in order to optimize efficiency, volume, and mass, while keeping the project as simple and cost efficient as possible by using only on-the-shelf components, including inductor and heatsinks. The impact of topologies on both efficiency and compactness is studied for a specific aeronautical application. A 2kW 3-level FCML module has been developed for a 100V to 28V DC-DC step-down. It relies on pairs of paralleled EPC2022 GaN transistors to significantly increase converter power density. Two routing strategies to reduce parasitic switching loops are compared using computer simulations, with experimental verification. First experimental results on a prototype show an efficiency up to 98.4% for a specific power of 12.5kW/L.
