Abstract Due to low switching frequency of high-power traction drive system, in wide operation range of train, multi-mode modulation algorithm is widely adopted in the traction inverters. This paper presents a multi-mode modulation algorithm based on selective harmonic elimination pulse width modulation (SHEPWM) and studies the smooth switching method between different modulation modes. After that, a design and realization scheme of this modulation algorithm based on FPGA is given in detail, and the top-level design logic and communication method between DSP and FPGA chips are analyzed. Finally, the hardware-in-loop (HIL) RT-LAB experiment platform with DSP (TMS320F28335) + FPGA (SPARTAN XC3S400) controllers has been designed and developed, and the FPGA implementation scheme of multi-mode modulation algorithm is shown. HIL experimental results have verified the correctness of the adopted multi-mode modulation algorithm and the feasibility of the FPGA design.

Key words： Multi-section modulation traction inverter selected harmonic eliminating pulse width modulation programming design in FPGA smooth commutation
