  • Abstract:Temperature control of magnetic controllers (concentrators, cores, shields, shunts) is an essential part of the induction coil design. Prediction and study of the coil copper have been described in a presentation “Influence of Cooling Conditions on Induction Coil Copper Temperatures” (V. Nemkov, R. Goldstein) [1]. That study was made using Flux 2D computer simulation program. The present study is devoted to temperature prediction and control in both copper and magnetic controller. Computer simulation with programs Flux 2D was used for modeling of the whole coil head operating conditions. Flux 2D has no standard option to account for magnetic losses in the concentrator material and their influence on the concentrator temperature. Special procedure has been developed to solve this problem. A case study illustrates the calculation procedure and influence of the coil head design, frequency, controller material selection and application technology on the controller temperature. New composite magnetic materials and temperature management methods are also described.
