I. Introduction
Isolated dc–dc converters are essential building blocks of modern high-power energy conversion systems, such as fast electric vehicle chargers, renewable energies, datacenter power supplies, drive systems, or more electric aircraft [1]–[4]. The usage of medium-frequency transformers and wide bandgap semiconductors allows the construction of more compact and efficient dc–dc converters [5]–[7]. Nevertheless, due to their limited gravimetric power density (i.e., 2–12 kW/kg), the magnetic-core transformers (MCTs) are typically the heaviest components of power electronic systems. This is particularly problematic for airborne or battery-powered applications [2], [8]–[11].
