摘要: 在脉冲功率技术中，开关电极的形状优化设计非常重要。利用电荷模拟法对常用的环形电极的电场分布进行了模拟计算，用旋转椭圆近似法优化电极轮廓外形，用微粒群（PSO）算法对轮廓外形的几何参数进行优化选择。结果表明：旋转椭圆近似法结合PSO算法非常适用于环形开关电极自动优化设计，优化所得形状和参数能满足电极之间电场分布的要求。

Abstract: The optimization design of the electrode was of great influence on the switch in pulsed power. The charge simulation method was used to simulate the electric field, the rotating ellipse method to optimize the electrode’s figure, the Particle Swarm Optimization method to select the best geometrical parameters, and the ANSYS electromagnetic analysis to emulate the electric field of the optimized result. The results indicate that the rotating ellipse method combined with the Parameters Scan method can be applied to the auto-optimization of the ring-shaped switch electrodes, and the electric field of the optimized figure and parameters can meet the requirements of electrical field.
