This article discusses the relationship between the losses of a sinus filter choke. Its influence on the loaded sinus filter temperature field distribution within and on the surface, verification of these performance and temperature relationships. It includes three-dimensional transient finite element analysis (FEA) of the sinus filter choke temperature conditions based on a mathematical description of the conduction, free convection and losses and describing temperature field validation methodology. In addition, there is shown mutual evaluation of the validation measurement and FEA simulation. Finally, there are outlined further options for the future optimisation of the sinus filter choke thermal simulation.
