Frequency Characteristics Analysis of High Frequency Current Transformers
Advanced Materials Research, 2014In this paper, the equivalent model of high frequency current transformers (HFCT) for partial discharge online monitoring and its major parameters’ influence on amplitude-and phase frequency characteristics are derived. An optimized design for HFCT for partial discharge online monitoring is summarized.

PHA: Patch-Wise High-Frequency Augmentation for Transformer-Based Person Re-Identification
Computer Vision and Pattern Recognition, 2023Although recent studies empirically show that injecting Convolutional Neural Networks (CNNs) into Vision Transformers (ViTs) can improve the performance of person reidentification, the rationale behind it remains elusive. From a frequency perspective, we

High frequency models of PCB-based transformers
Proceedings of the 44th IEEE 2001 Midwest Symposium on Circuits and Systems. MWSCAS 2001 (Cat. No.01CH37257), 2002An equivalent network of PCB-based transformers with two windings is presented for use at high frequency (some MHz). After raising some criticisms to the traditional high frequency transformer model, a systematic procedure is presented to deduce the inductive and the capacitive coupling model of a two windings transformer.

High frequency loss evaluation in high frequency multi-winding power transformers
Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95, 1995A high frequency power transformer (HFPT) with twin secondaries is generally analyzed with each primary ampere-turn being canceled by an equal contribution from each of the two secondaries. Such a methodology does not indicate worst case high frequency losses.
