1. Choice of structures based on available technologies

Increasingly demanding specifications in power electronics require converters to be increasingly compact, while guaranteeing high efficiency and environmental compatibility. To achieve these objectives, two avenues can be explored: the use of high switching frequencies to reduce volume and mass, and/or the implementation of new interleaved structures. The first important and widely explored parameter is the switching frequency. Higher frequencies reduce the volume and mass of passive components; however, higher frequencies lead to higher losses in all components: iron and copper losses in magnetic components, and switching losses in semiconductors. Moreover, this rise in frequency has its limits in differential-mode filtering, given the harmonics that are constrained by EMC templates
