Abstract :
This paper presents an analytical model and optimization process for multiple floating field limiting ring (MFFLR) structure pursuing high voltage blocking capability with evenly distributed electric field. The three-dimensional (3-D) model considers both the sphere-junction effect and cylindrical-junction effect, which formulates an accurate 3-D model for optimization. Design example obtained by the proposed method is examined with MEDICI simulation and consistent results are observed.
