“…By increasing the magnetic flux density and reducing the leakage inductance of the TR, efficiency improvement and volume reduction can be achieved. However, the conventional TR has been optimised almost fully [7–12]. Hence, it will be difficult to improve the efficiency or reduce the volume of a conventional TR, significantly, which in turn makes it difficult to optimise a converter using the conventional TR.…”

Recently, power conversion systems (PCSs) have exhibited high efficiencies and miniaturisation, and this trend is expected to grow in the future. An important component of the PCS, which accounts for a significant portion of its volume, is the transformer (TR). However, it is difficult to achieve a significant increase in the efficiency and reduction in the volume of a PCS using a conventional TR, as the conventional TRs do not offer much scope for further optimisation. To overcome this limitation imposed by the conventional TRs, a novel and practical high-frequency coaxial TR, named the shell-type coaxial TR (SCTR), is proposed in this work. A useful and strategic analysis and design method, which covers the overall development process from the design stage to the experimental validation stage of the proposed high-frequency SCTR, is also proposed. The usefulness of the proposed SCTR and the analysis and design method are verified by designing an SCTR for a 50 W DC/DC converter and conducting experiments on it. It is found that the use of the proposed technique can cause a significant increase in the efficiency and power density of the PCS

The limitation in the open load condition can be made by reducing the primary voltage, changing the input impedance, or a combination of both.…”
