The nonlinear characteristics of the thyristor and its real-time fault injection problem greatly challenge the hardware-in-the-loop (HIL) implementation of high-speed linear motors (HSLM) with power supply switching faults. In this paper, a real-time simulation model based on the improved associated discrete circuit switch model is proposed by analyzing the operating characteristics of the thyristor in healthy and faulty states. The entire segmented power supply system is constructed on an FPGA-based HIL platform using the fixed-point schematic to verify the correctness of the proposed model. The results of the offline simulation and HIL test demonstrate that the proposed model can precisely reflect the current asymmetry caused by the mutual asymmetry inductance of the stator windings after a power switching fault. The research can provide a test platform for fault diagnosis algorithms and control protection strategies for HSLM with segmented power supply systems.
