The main objective of this proposal is to investigate and commercialize the next generation of universal power converters for aerospace applications. In aircraft, electricity is generated by AC generators and then is converted into DC by autotransformer rectifier units (ATRU) to power different kinds of electrical loads including motor drives and actuators. In the past decades, the ATRU has been widely used in aircraft although it has lower power density. With increasing power demand in increasingly electrical aircraft (the More Electric Aircraft or MEA), the ATRU becomes the bottleneck in modern aircraft power conversion designs. This project will investigate possible converter topologies with high power density and high reliability to replace the ATRU in aerospace applications. Through this project we expect to improve the power density from 1kW/kg for normal ATRU powered system to 5kW/kg with air cooling or 8kW/kg for liquid cooling. It is also expected that through this project we will be able to bring the proposed power converter technology to an acceptable readiness level for commercialization.

这项提议的主要目标是研究用于航空航天应用的下一代通用功率转换器并将其商业化。在飞机上，电力由交流发电机产生，然后由自耦变压器整流单元(ATRU)转换为直流，为包括电机驱动器和执行器在内的不同类型的电气负载提供动力。在过去的几十年里，ATRU虽然功率密度较低，但在飞机上得到了广泛的应用。随着越来越多的电动飞机(即MEA)对电力需求的增加，ATRU成为现代飞机功率转换设计的瓶颈。该项目将研究具有高功率密度和高可靠性的可能的转换器拓扑，以取代航空航天应用中的ATRU。通过这个项目，我们希望将ATRU动力系统的功率密度从正常ATRU系统的1kW/kg提高到5kW/kg，空气冷却或液体冷却的功率密度将提高到8kW/kg。预计通过这一项目，我们将能够使拟议的电力转换器技术达到可接受的商业化准备水平。
