Abstract The structure and principle of electric traction drive system are analyzed, and a field-programmable gate array (FPGA) model is built for hardware-in-the-loop (HIL) simulation, to meet the demand of real-time high speed simulation. This model consists of a single-phase rectifier, the DC-link circuit, a three-phase two-level inverter and asynchronous motors. For the inverter and rectifier which include switching devices, logical expression functions are derived under different switching states. State equations and matrix equations are applied in modeling converters and asynchronous motors respectively. In addition, the mathematical model is integrated into the FPGA chip. The test on HIL simulation in the RT-LAB real-time simulator has verified this FPGA model. As a result, the simulation step decreases sharply, breaking the speed limit of general-purpose processor. The real-time HIL simulation method at microsecond level improves the response speed and accuracy of the electrical traction drive system modeling.

Key words： Field-programmable gate array microsecond hard-in-the-loop electric traction drive system real-time simulation AC-DC-AC
