| Abstract: | Under high-frequency AC conditions, capacitor banks experience significant thermal accumulation due to the combined effects of high electric fields and high-frequency currents, leading to performance degradation and potential safety risks. To overcome the limitations of conventional thermal models, which assume constant material properties, a nonlinear electrothermal finite element model incorporating the temperature-dependent resistivity of biaxially oriented polypropylene (BOPP) is developed herein. This model incorporates the electric field distribution, Joule heat generation, and heat transfer across multi-material interfaces under realistic operating conditions. According to this experimentally validated model, both internal heat generation and steady-state temperature rise are strongly influenced by the nonlinear temperature-dependent BOPP resistivity, which plays a key role in the thermal stability of high-frequency AC capacitor banks.
