Abstract. This paper performs an analysis of the electric power conversion methods, and also examines the development trends of DC-to-DC, AC-to-AC, AC-to-DC and DC-to-AC power converters with the use of the International Patent Classification (2023). A comparison has been made of such different kinds of converters as power converters with intermediate conversion and without intermediate conversion into AC or DC, converters using devices of a transistor and thyristor type, and specific circuit implements corresponding to the IPC classification. Perspective directions of such converters’ development have been revealed. The analysis was carried out on the basis of the US patents databases which were formed by the authors for the IPC groups H02M3, H02M5, H02M7 within 2012 to 2023. The perspective directions were revealed by constructing time series of the US patents for the analyzed power converters and their further comparison by the issued patents number and growth patterns. As a result of research, the advantage of transistor converters circuits has been proved, the perspective development directions of the electric power parameters conversion methods as well as their implementation have been described. There was found a decrease of the issued US invention patents in the considered IPC groups by 40% within 2019 to 2022.
Key words: electric power converter, conversion method, direct current, alternating current, International Patent Classification, US patents, USPTO, development trends.
