On the other hand, the mixed modulation algorithm uses the five-segment modulation algorithm and the characteristic quadrangle to approximate the reference vector which can reduce the switching frequency. Finally, a three-cell seven-level inverters experiment platform is set up.

另一方面，混合调制算法利用特征四边形法和五段算法逼近参考矢量减少了开关切换频率。
