Abstract
This paper presents the configuration of a high frequency (HF) coaxial winding transformer with Faraday shield and discusses the shielding effect of the transformer in the high frequency range. The experimental results show the voltage ratio, coupling coefficient and load characteristic of the HF coaxial transformer in the range up to 2 MHz. The numerical result illustrates the eddy current distribution in the windings and shielding coil, and the magnetic flux distribution in the shielded HF coaxial transformer.
