| 摘 要： | 提出一种基于非直角坐标系的两电平SVPWM控制算法。在此基础上采用新型电压空间矢量脉宽调制(SVPWM)算法将三电平逆变器的电压空间矢量平面简化至两电平平面。在DSP中将两电平逆变器的电压空间矢量控制算法应用于三电平逆变器中。实验结果证明该算法实现简单,性能良好。

| Abstract: | This paper proposes a kind of non-rectangular coordinates,based on which a new algorithm of two-level inverter can be obtained.A novel simplified space vector pulse width modulation(SVPWM) method is implied to simplify the space-vector diagram of a three-level inverter into that of a two-level inverter.The space-vector module algorithm of a two-level inverter is applied to the three-level inverter with DSP.The experimental result verifies the effectiveness of SVPWM modulation algorithm,and the new method ca... |
