摘　　要：dSPACE因为与MATLAB/Simulink的无缝接口,极大地缩短了算法验证的周期。从dSPACE底层DWO语言出发,编写DWO模块与对应的s-function文件,扩充了dSPACE的DS5101板卡Lib中的脉冲触发模块,使其能触发最多16路脉冲。通过FPGA对输出脉冲进行后续死区和窄脉冲处理,实现了dSPACE验证三电平算法的能力。基于虚拟电网磁链定向的三电平PWM整流器矢量控制策略,使用扩充DWO模块在双三电平变频器系统中进行了实验验证研究。实验结果表明,基于扩充DWO模块的dSPACE平台可以替代DSP+FPGA控制方法,极大地提高了算法验证速度和准确性。dSPACE,with seamless interface to MATLAB / Simulink, greatly shortened the algorithm validation experiment cycle. Start from the dSPACE underlying DWO language, the DWO module and the corresponding s-function file were written, and DS5101 board Lib pulses trigger module was expanded, triggering up to 16 pulses. Follow-up dead-band and narrow-pulse of the output pulse are reformed through the FPGA,achieving the ability of the dSPACE to verify the three-level algorithm. Based on virtual grid flux-oriented three-level PWM rectifier vector control strategies, experiment is made to prove the feasibility of the expansion DWO modules. The experimental results show that the dSPACE platforms with the DWO module can replace the DSP ＋ FPGA control method, greatly improving the speed and accuracy of the algorithm verification.
