摘 要: | 空间矢量脉宽调制(space vector pulse width modulation,SVPWM)能够保证在电机的定绕组中产生较小的电流谐波,与采用正弦调制的方法相比,SVPWM能保证高直流侧电压的利用率。从坐标变换角度介绍了SVPWM的实现方法,并介绍了脉宽调制原理、驱动交流电机三相逆变器的工作原理和SVPWM的矢量合成,给出了SVPWM相关参数的求导公式。最后,介绍了在DSP2812实验平台上SVPWM的实现方法。 |

Abstract: | Space vector pulse width modulation (SVPWM) can guarantee that the winding of the motor produces little harmonic, and compared with the method of sinusoidal modulation, it can improve the utilization on the direct current (DC) side. This paper introduces the implementation method of the SVPWM based on coordinate conversion, and introduces the principle of pulse width modulation (PWM), the work principle of three-phase inverter, the vector synthesis of SVPWM, and deduces the parameters of SVPWM. Finally, the implementation of SVPWM on DSP2812 is introduced. |
