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...
