图7分别对比了修正前后零序环流峰值的情况，图中数值以VDCTs/8Lc

Figure 7 compares the peak values ​​of zero-sequence circulation before and after the correction. The values ​​in the figure are standardized based on VDCTs/8Lcm. <br>451 <br>Since the lowest zero-sequence circulating current change slope in the vector combination of the short vector and the medium vector is ±1, combined with the symmetry of the vector sequence in the switching period, the maximum peak value of the zero-sequence circulating current Izmax can be optimized as VDCTs under the interleaved carrier framework. /8Lcm.

Fig. 7 compares the peak value of zero-sequence circulation before and after correction respectively, and the values in the figure are standardized based on VDCTs/8Lcm. Four hundred and fifty-one Because the lowest slope of zero-sequence circulating current in the vector combination of short vector and medium vector is 1, combined with the symmetry of the vector sequence in the switching period, the maximum value Izmax of zero-sequence circulating current can be optimized to VDCTs/8Lcm at the lowest in the staggered carrier frame.
