Abstract :
This paper presents the optimization of the loss efficiency of inductive heating devices by the application of a sensitivity approach. Based on a mixed potential FE skin effect problem a new sensitivity formulation is derived and extended to the adjoint variable method. Through this the time for the calculation of the cost function and its gradient is minimized. The algorithm is applied to the positioning of the field turns of a simple inductive heating device. Finally the optimization of a crucible induction furnace is shown
