It can be seen that, compared with the traditional DPWM algorithm, the modified MDPWM algorithm has a better zero-sequence circulating current peak value in the full modulation range. <br>573 <br>In addition, the maximum value of the zero-sequence circulating current peak value of all MDPWM algorithms in the full modulation range is greatly reduced, which is only half of the traditional algorithms except DPWM3, which is consistent with the theoretical analysis in Section 4.
