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 However, this assumption is no longer valid for high-frequency transformers (HFTs).
