Abstract :
The fabrication and application of high-permittivity ceramic materials for use in power electronic circuits are investigated. The ability to manufacture materials with a wide range of εr values and the influence of dielectric permittivity on the circuit behaviour of a converter employing planar connections are studied. It is shown conclusively that the circuit behavior of a power electronic circuit can be modified by only varying the properties of the materials used for supporting the connections. This mechanism can be used to improve the power transmission characteristics of the connections. Methods are described whereby the dielectric properties of BaTiO3-based materials can be varied over a very wide range of 4⩽εr⩽1300. The material is manufactured in the form of tiles that can be used to support connections, acting both as insulation and as a medium to help control circuit performance
