摘　　要：脉冲功率技术广泛用于科学研究、军事、医学及工业等方面。脉冲放电电路为脉冲功率技术的主要研究对象,以高电压、大电流、高功率为特点。电路电感是脉冲放电电路的一个主要关注点,计算机仿真技术(CST)软件为快速计算电路电感提供了一种方法。根据导线间的磁场分布推导了导线电感的理论公式,分析了导线半径及导线间距对电感的影响;分析了基于脉冲放电电路电流波形迭代求解电路电感方法;最后利用CST建模计算了不同电路的电感。将CST计算电感与基于脉冲放电电路电流波形迭代求解的电感做对比,CST可用于辅助分析脉冲放电电路。Pulsed power technology is widely used in scientific research, military, medicine, industry, and so on. Pulsed discharge circuit, as the main research object of pulsed power technology, is characterized by high voltage, high current and high power. Inductance is one of the main concerns of pulsed discharge circuit, and a method is provided by the Computer Simulation Technology（CST） to calculate circuit inductance rapidly. In this paper, theoretical formula of wire inductance is derived based on magnetic field distribution between wires, the influence of the wire radius and the distance between wires on the inductance are analyzed. And then, iterative method of solving circuit inductance with current waveform of pulsed discharge circuit is introduced. Inductance of different circuits is calculated by means of CST finally. Comparing the inductance calculated by iterative method with that by using CST, a conclusion is drawn that CST can be utilized to analyze the pulsed discharge circuit.
