    Abstract
    In order to suppress high frequency (HF) noise, a Faraday shield was used in a HF isolation coaxial transformer design. The effect of the Faraday shield on current and flux distribution and the power loss compared with the no shield case is numerically analyzed for different winding arrangements under both open circuit and short circuit conditions. An optimized shield thickness and its position between the primary and secondary windings are determined by taking into account the coil configurations and load conditions. The intra- and inter- capacitances of a HF transformer with a shield or no shield case were also numerically ...

    In order to suppress high frequency (HF) noise, a Faraday shield was used in a HF isolation coaxial transformer design. The effect of the Faraday shield on current and flux distribution and the power loss compared with the no shield case is numerically analyzed for different winding arrangements under both open circuit and short circuit conditions. An optimized shield thickness and its position between the primary and secondary windings are determined by taking into account the coil configurations and load conditions. The intra- and inter- capacitances of a HF transformer with a shield or no shield case were also numerically analyzed. The calculated inter - capacitance is in good agreement with the experimental result.
