Generalised Tapped Inductor Switcher (GTIS) approach to modelling of high‐order converters
IET Power Electronics, 2021 A generalized modelling technique suited to integrated and high order Pulse‐Width‐Modulation (PWM) topologies is studied and proposed here. Most integrated converters have their switches shared by more than one inductive element. The proposed generalised

Variation of Core Loss in High-Frequency Transformers Under Different Load Conditions
IEEE Open Journal of the Industrial Electronics Society, 2023 Typically, the core loss of transformers is considered constant, regardless of the load conditions on the secondary side. However, this assumption is no longer valid for high-frequency transformers (HFTs).
