I. Introduction
Electric power converters play the critical role of performing power processing in a wide range of applications such as switched mode power supplies for portable devices (in watts level), household applications, industrial applications (in kilowatt level), and dc–dc and dc–ac microgrids (in megawatt level). Over 70% of used electricity is estimated to be processed by power converters [1], and current trends in increasing electrification toward less carbon-intensive technologies are likely to increase this number [2]. Given their widespread use and importance, power converter efficiency plays an important role and has a high relevance for the environmental impact of electronic devices. Therefore, in order to achieve the desired voltage and current ratings, a power converter has to be carefully designed in a manual process. This process ensures that power converters are customized and optimized to improve their efficiency according to their respective application and desired specifications [3], [4], [5].
