摘要
在介绍三电平中点钳位型逆变器SVPWM控制策略基础上,本文结合DSP和FPGA各自的优点,设计了基于FPGA和DSP的中点钳位型三电平逆变器。并对SVPWM的控制策略进行了实验研究,得出了相电压、线电压和电流波形,实验结果表明了三电平NPC逆变器SVPWM方法的有效性。
Based on the description of SVM algorithm for three-level neutral-point-clamped VSI, a three-level neutralpoint-clamped inverter is designed, combining the merit of DSP with FPGA. The waveform of phase voltage, line-to-line voltage and current are measured. Experiment results show that the Space-vector Pulse Width Modulation Algorithm is effective.
