Abstract: A 2-stage three-level power conversion system（PCS）was studied，in which the 3-level T-type 3-leg3-phase 4-wire（3LT23L3P4W）topology was adopted as AC/DC part while the 3-level Buck/Boost topology wasutilized as DC/DC interface. To address the neutral point potential（NPP）unbalance of the PCS，firstly，with thea...
