unit sampling

The modulation method for multi modular phase shifted SVM technique is to stagger the sampling time of each converter unit, and to make the sampling time of the adjacent converter unit deviate by 2 π/ ( KN).

组合变流器相移SVM技术的调制方法，就是将各变流器单元的采样时间错开，使得各变流器单元使用相同的SVM算法，相邻变流器单元间的采样时间相差2π/（KN）的角度。
