Abstract: The failure rate of aluminum electrolytic capacitor (AEC) is high in power electronic systems. Due to the complex structure of AEC, it is difficult to establish an actual model, so experiments are the common way to analyze the failure of AEC. Thus, this paper proposes a finite element method (FEM) for AEC considering electrolytic failure.
Liu, Y., Abali, B.E., Yang, H. et al. Plate capacitor problem as a benchmark case for verifying the finite element implementation.
For this kind of problem, FEM shows good adaptability and flexibility, since the proposed implementation not only allow to study the presence of various dielectric layers between parallel plate capacitors, but also have the potential to study the dielectric layers with irregular shapes.
Electric field distribution as obtained in Sect. 3 around the edge of a two-dimensional parallel plate capacitor model These ideal capacitance equations assume that the electric field is uniform and also perpendicular to the capacitor electrodes. These simple forms fail to account for fringing effect (also called edge effect).
Finally, a transient solution that includes dielectric loss and calculates the quality factor of a capacitor is presented, which may be used in capacitor design. Convergence and consistency of results are demonstrated by comparing the results between analytical and numerical solutions and also the results from different boundary conditions.
