摘　　要：分析了二极管钳位式5电平逆变器的拓扑结构及基于60°坐标系的SVPWM算法,搭建了Matlab仿真模型,并设计了基于DSP和FPGA的控制系统。DSP发出三相上桥臂12路PWM脉冲,FPGA完成对PWM脉冲的扩展和死区添加,输出24路带有死区的PWM脉冲。最后选用TI公司TMS320F28335DSP和Altera公司EP3C25FPGA对该系统进行实现,并在硬件平台上进行试验,实验结果验证了该拓扑结构和SVPWM算法的正确性。The diode-clamped five-level inverter topology and SVPWM algorithm based on the 60° coordi- nate system were analyzed, built a Matlab simulation model and designed control system based on DSP and FP- GA. DSP generated three-phase 12-channel PWM pulses on the bridge, and FPGA completed the expansion of the PWM pulse and added dead zone,and generated 24 PWM pulses with dead zone. Finally,this system was implemented on the TI＇s TMS320F28335 DSP and Altera EP3C25 FPGA and test was completed on the hard- ware platform. Experimental results verify the correctness of this topology and SVPWM algorithm.
