Computer-Aided Identification of Equivalent Power Electronics Converters

Equivalent power electronics converters (PECs), which have same performance characteristics but dissimilar configurations, are easily mistaken as different converters to be repeatedly studied in the practice, resulting in extra workload. Therefore, it is essential to implement the equivalence identification to avoid the undesired repeated research. In order to accomplish this goal, a computer-aided solution is proposed in this letter, aiming to quickly and precisely identify the equivalent PECs. First, two identification rules are figured out, with which different PECs can be systematically judged to be equivalent or not. Then, software Altium Designer is used to automatically acquire the information of PECs, including the components and the connecting relationships. After that, software MATLAB is utilized to further complete the data process, circuit loop search, and final judgment. Compared with the conventional manual identification method, which is totally dependent on researcher's effort, the proposed computer-aided scheme is more convenient, accurate, and practical, which is beneficial for the topology research in both academic and industrial fields.
