Hello everyone, I am trying to implement 3 level space vector modulation for a multilevel inverter. Without mapping vector for region selection of three level space vector, I am getting reference angle started from sector-1 to sector-6 as shown in ''theta_ref'' file. But when I am implementing mapping references for region selection (please see in the attached file ''mapping_reference''), the reference angle is shifting 180 degree that means it is starting from sector-6 to sector-1 as in attached file ''theta_ref_with_region_identification''. Could anyone please let me know why this is happening and how to solve this problem?

Thanks in advance.
