Abstract The current loop transient model (CLM) of the asynchronous induction coil launcher (AICL) is presented. Add the mathematical model of inverter which is described with switch function, thus the improved CLM is applied to simulation of frequency control system. The field-circuit coupled model is built in Maxwell/Simplorer. The simulation results of the two models are consistent when driven by constant voltage source and inverter, and the accuracy of improved CLM is verified. The temperature rise of projectile is calculated based on CLM, and the influence on emission performance is also analyzed. A 9 stages coil launcher prototype and related frequency conversion circuit are constructed. The measured force and muzzle velocity are basically consistent with simulation results. Comparing with finite element model, the CLM can reduce computational complexity and simulation time. These will be helpful for the parameters tuning and optimization which is an important tool for analyzing the transient characteristics of AICL.
