This paper describes the implementation of a complete design tool for design, analysis, optimization and production of PCB embedded inductors. The paper shows how LiveLink™ for MATLAB® and COMSOL Multiphysics® make it possible to combine the scripting and calculation power of MATLAB with the simulation power of COMSOL Multiphysics in order to get an extremely efficient tool for inductor design. The tool has been used to investigate PCB embedded spiral, solenoid and toroidal inductors. Due to the fact that the spirals are axisymmetric they can be simulated in 2D, which speeds up the simulation significantly. This is not possible for the solenoid and toroid, hence complete 3D structure has been made and simulated for these structures.
