Bidirectional SiC three-phase AC-DC converter with DQ current control

Grid connected Electric vehicles (EVs) and Plugin hybrid electric vehicles (PHEVs) can benefit the grid by utilizing Vehicle-to-grid (V2G) technology. V2G enables stored electrical energy in electric vehicle batteries to be returned to the grid for peak demand and other ancillary services. Typically, the onboard electric vehicle battery charger is uni-directional but needs to be bi-directional to enable V2G capabilities. A modulation strategy for DQ (direct-quadrature axis) current control of a single stage, isolated, bi-directional three phase AC-DC converter based on Dual Active bridge (DAB) is presented. Mathematical analysis of the converter with DQ current control is discussed with simulation results confirming the analysis.
