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 However, this assumption is no longer valid for high-frequency transformers (HFTs).

Note: Investigation of a Marx generator imitating a Tesla transformer
, 2018 A compact Marx generator was built to mimic a spark-gap Tesla transformer. The generator produced radio-frequency pulses of up to $\pm$200 kV and $\pm$15 A with a frequency between 110 to 280 kHz at a repetition rate of 120 Hz.
