Abstract This paper presents analysis and measurement results of a high-frequency (HF) coaxial transformer with Faraday shield. The simulation results demonstrate that the magnetic flux and eddy current distribution are not impacted by the inclusion of a Faraday shield. The Faraday shield's maximum eddy current density is less than 17% of the maximum density found in either of the other two windings. The experimental results demonstrate that the voltage ratio, coupling coefficient and load characteristic of the HF coaxial transformer with Faraday shield at frequencies up to 1 MHz are in agreement with the turns ratio and load regulation for a transformer in which capacitive effects are neglected.
