摘要

摘要:
随着新能源发电、电气化交通等领域的兴起，电能变换的需求日益多样化，需要更多的隔离型直流变换器(即隔离型DC-DC变换器)拓扑。为解决基于人工经验生成拓扑的偶然性和无法进行拓扑优化的问题，提出一种基于顶点素数度的两开关隔离型DC-DC变换器拓扑自生成方法。提出双顶点对变压器模型，利用图论将电路转换为图；将构成电路的元器件的数量和种类作为输入条件，利用所提的拓扑自生成方法遍历生成具有给定元器件的所有可用隔离型DC-DC变换器拓扑。以隔离型T¹S²D²L¹C¹DC-DC变换器为例，即变换器电路由1个变压器、2个开关管、2个二极管、1个电感、1个电容、1个输入直流源和1个输出直流源组成，可一次生成87种可用正激变换器和97种反激变换器拓扑，以正激变换器为例，根据电压增益可分为25种升压正激变换器、24种降压正激变换器、32种升降压正激变换器和6种等压正激变换器。所提方法实现了基于计算机编程快速、量化生成新的隔离型DC-DC变换器拓扑，为工程应用提供了拓扑库，为拓扑优化选型提供了条件。

Abstract:
More isolated DC-DC converter topologies are required as a result of the growing need for different power conversion brought on by the development of new energy generation and electrified transportation. To overcome the randomness and lack of topology optimization in generating topologies based on human experience, this paper proposes a vertex prime degree-based topology self-generation method of the isolated DC-DC converters with two switches. Firstly, the two-vertex-pair transformer model is proposed, and the circuits are converted into graphs using graph theory. Secondly, the numbers and the types of components used to form the circuit are regarded as the input condition of the method. Finally, the proposed self-generation method is utilized to traverse and generate all available isolated DC-DC converter topologies with the given components. An input DC source, an output DC source, two switches, two diodes, one transformer, one inductor, and one capacitor, namely, the isolated T¹S²D²L¹C¹ DC-DC converters are examples of converter circuits. The 87 forward converters and 97 flyback converters can be generated. Taking the 87 forward converters as examples, they can be further categorized based on voltage gain into 25-boost forward converters, 24-buck forward converters, 32 buck-boost forward converters, and 6 constant voltage forward converters. Therefore, this method enables rapid and quantitative generation of new isolated DC-DC converter topologies through computer programming. It provides a topology library for engineering applications and establishes conditions for topology optimization and selection.
