摘　　要：大功率牵引传动系统具有低开关频率的特点,在列车运行全速域范围内,牵引逆变器广泛采用多模式调制算法。该文给出了一种基于特定次谐波消除脉宽调制(SHEPWM)的多模式调制算法,并加入切换控制算法以保证不同模式之间平滑切换。然后,给出该算法基于现场可编程逻辑门阵列(FPGA)的详细设计方案,分析顶层设计逻辑和通信方法。最后,搭建基于DSP(TMS320F28335)+FPGA(SPARTAN XC3S400)为控制器的RT-LAB半实物实验平台,对该多模式调制算法进行了半实物实验研究,并给出多模式调制算法的FPGA实现设计方案。半实物实验结果验证了该算法的正确性和FPGA设计方案的可行性。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.
