On the Analysis and Design of High-Frequency Transformers for Dual and Triple Active Bridge Converters in More Electric Aircraft
摘要：
具有电流隔离的DC-DC转换器是飞机直流配电系统中的关键元件，双有源和三有源桥式转换器是该应用中最有趣的候选者之一。高频Transformer漏感在这些变换器的交流环节中起着关键作用。该泄漏电感确定转换器的功率传输能力并形成AC链路电流。漏感值与Transformer绕组的分布有关，并随交流环节电流的有效值而变化。本文首先针对多电飞机直流电力系统的双、三有源桥式变换器设计了高频Transformer。然后，在三种不同的绕组配置和不同的交流链路有效值电流值的Transformer的泄漏电感的Ansys/Maxwell有限元分析。最后，通过Ansys/Maxwell瞬态分析验证了该设计的瞬态性能。
英文摘要：
DC-DC converters with galvanic isolation are a key element in the aircraft DC distribution system and Dual and Triple Active Bridge converters are one of the most interesting candidates in this application. The high-frequency transformer leakage inductances play a key role in the AC Link of these converters. This leakage inductances determine the power transfer capability of the converter and shape the AC link currents. The leakage inductance value is related to the distribution of the transformer windings and it changes with the RMS value of the AC link current. In this paper, first a high frequency transformer is designed for a Dual and Triple Active Bridge converter for the More Electric Aircraft DC power system. Then, an Ansys/Maxwell Finite Element analysis is performed on the leakage inductances of the transformer in three different winding configurations and in different AC link RMS current values. Finally, the transient performance of the design is validated by the Ansys/Maxwell Transient.
