Abstract: Based on the traditional space-vector pulse width modulation(SVPWM) algorithm for three-level inverter, a fast SVPWM algorithm was realized by using a “DSP+FPGA” combination. With the control method, the new method was carried out based on FPGA and DSP. The maximum utilization of the resources was realized, the rapiditay of the inverter control was improved, the more resources were provided for the grid connected experiment. Finally, simulation and experimental results were compared. It shows high degree of concordance.
Key words: inverter; three-level; space-vector pulse width modulation(SVPWM); digital signal processing(DSP); field-programmable gate array(FPGA)
