电力电子仿真中开关时刻自校正插值算法
A Switching Point Self-Correction Interpolation Algorithm for Power Electronic Simulations
摘要
Abstract
Power electronic switches often cause frequent topology changes, bringing new challenges for power electronic simulations. In this paper, aiming to resolve two key issues, i.e., fast resynchronization and numerical oscillation removal, a new component-level electromagnetic transient modeling method (2-stage diagonal implicit Runge-Kutta (DIRK) method) is designed. Then, a new switching point self-correction interpolation method is proposed based on DIRK method. In this algorithm, only one interpolation and value adjustment is required to complete interpolation process. Simulation results validate effectiveness of the proposed method.关键词
