Abstract

Power electronic converters are so crucial in the integration of different energy sources in the concept of Hybrid Energy System (HES). A three input DC-DC converter with buck-boost operating capability is introduced in this paper. The converter is capable of integrating energy sources which have different V-I characteristics. The output equation of the DIDC converter is derived from different working states using voltage - second principle. Also, the converter which has been presented in this paper can incorporate a single source or multiple sources with a small modification in the converter structure. This converter topology is designed and simulated in MATLAB / SIMULINK platform. Three input sources with different voltage levels such as 30 V, 20 V and 10 V are used for the performance evaluation of the converter. A small scale experimental setup has been developed to check the performance evaluation of the converter in real time condition and the results are incorporated. Also the efficiency profile of the converter under various loading condition has been analyzed which clearly shows that the presented converter has a good efficiency level.

用于混合能源应用的三输入dc-dc变换器

在混合能源系统(HES)概念中，电力电子变流器在不同能源的集成中起着至关重要的作用。介绍了一种具有降压升压工作能力的三输入DC-DC变换器。该变换器能够集成具有不同V-I特性的能源。利用电压秒原理推导了不同工作状态下DIDC变换器的输出方程。此外，本文提出的变换器可以合并单源或多源，只需对变换器结构进行少量修改。在MATLAB / SIMULINK平台上对该转换器拓扑结构进行了设计和仿真。采用30 V、20 V、10 V三个不同电压等级的输入源对变换器进行性能评价。建立了小型实验装置，实时验证了变换器的性能评估，并将结果纳入其中。分析了该变流器在不同负载条件下的效率曲线，表明该变流器具有良好的效率水平。
