摘要:
针对四桥臂逆变器常规空间矢量脉宽调制(SVPWM)需进行坐标变换的问题,对四桥臂逆变器的SVPWM和正弦脉宽调制(SPWM)两种调制技术进行了分析,给出了一种快速数字化三维(3D)SVPWM算法,无需坐标变换,节约了计算时间;证明了常规3D-SPWM改进后,与3D-SVP-WM完全等效,两者是归一化的,而且本质上均为逆变器最优跟踪控制方程的解,可获得最大直流电压利用率。SVPWM比SPWM算法更简单,是工程应用的首选。给出了详细的仿真结果,在一台四桥臂样机上验证了结论的正确性。
Abstract:
Coordinate transformation is necessary in conventional space vector pulse width modulation(SVPWM) scheme of the fou-leg inverter.The SVPWM and sinusoidal pulse width modulation(SPWM) techniques used in four-leg inverter were analyzed in detail.A fast digital three-dimensional(3D) SVPWM algorithm which eliminates coordinate transformation and saves calculating time was proposed.Conventional 3D-SPWM with improvement was equivalent to 3D-SVPWM absolutely was proved;they were two unified PWM methods.In nature,t...
