磁绝缘电压叠加器功率流的电路计算方法

摘要

以已建成的10级直线变压器驱动源系统为依托,以传输线计算方法为基础,通过引入空间电荷限制流和磁绝缘流阻抗模型,对感应电压叠加(IVA)真空功率流的电路计算方法进行了探索,开发了包含磁绝缘过程的全电路计算程序,提供了一种快速评估该IVA系统真空功率流的方法.计算结果表明:对磁绝缘状态下流阻抗的描述是该方法准确计算的关键；解决好算法的数值稳定性,避免数值振荡的发生,是将这一方法推广应用的重要前提.%A method to calculate power flow for magnetically-insulated inductive voltage adder was developed based on the transmission line algorithm, in which space charge limited flow and magnetic insulation flow were introduced. This method can estimate the power flow of a 10 stage LTD system faster than PIC simulation. The description of flow impedance in magnetic insulation phase is the key to the accuracy of this method, and the numerical stability is an important prerequisite for its application.
