With the continuous promotion of “dual-carbon” goals and the increasing demand for re-electrification development, the construction of new power electronic converters is still one of the research hotspots in the field of power electronics. However, the traditional topology construction method relies on designers’ experience, so the design process is inefficient, and the design method lacks generality. Therefore, the intelligence of topology construction contributes to improving the efficiency and generalization of topology design. A DC-DC converter is taken as an example, first, the process of power electronic converter intelligent construction is divided into three main links, i.e., topology description, topology generation and topology performance analysis. Then, the topology description method, topology construction rules, topology constraints and topology performance indicators suitable for intelligent construction are described in turn. Finally, the realization of topology intelligent construction based on a programmable search algorithm and reinforcement learning is introduced. The research shows that the power electronic converter topology intelligent construction has just started, and there is still a lot of work to be carried out in multi-type topology construction, multi-objective optimization, performance intelligence analysis, etc.
