Abstract

This paper highlights some areas in the traditional inductor design realisation that lead to poor analytical prediction of inductance, saturation and magnetic core utilisation. A novel winding scheme including a dual-coil winding and a ´phantom´ turn has been proposed to remedy the major inaccuracies and to better utilise the magnetic core of the inductor. 3D finite element analysis and a prototype have been used to verify the proposed winding topology
