Abstract: Due to the high cable ratio of city grid，the harmonic pollution is aggravated. For the buses with high harmonic voltage content，it is necessary to evaluate the harmonic emission level of the utility side and customer side. Most of the existing evaluation methods are based on two assumptions：1）the harmonic ...

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...
