能量路由器电磁暂态半隐式延迟解耦建模方法
A Semi-implicit Delay Decoupling Modeling Method for Electromagnetic Transient of Energy Routers
摘要
Abstract
The energy router has a complicated topology,many power devices,high switching frequency,and when detailed models are used for electromagnetic transient simulation,the speed is slow and the efficiency is low.Based on the semi-implicit delay decoupling method,this paper establishes a general decoupling model of energy routers,which can realize the fine-grained decoupling between the link level and the modules and the parallel simulation.According to the matrix splitting and delay technology,firstly derive the semi-implicit decoupling model of the H bridge,the cascade and parallel models of the H bridge,and then splice the decoupling model and the power coupling module to obtain the semi-implicit solution of energy routers of different topologies.Coupling model.Finally,an example is used to verify the accuracy and effectiveness of the method in this paper in terms of simulation accuracy and efficiency.关键词
