Abstract

Three-phase dual active bridge (DAB3) converters are considered as a favora-ble choice in dc microgrids. To further enhance its power quality, LC filters are typically employed as input filters cascaded with three-phase DAB con-verters. However, mismatched parameters can potentially cause stability is-sues in the cascaded system. To address this challenge, this papeSr establish-es a state-space averaged small-signal mathematical model of the DAB3 converter. Additionally, the input impedance models of the LC-DAB3 con-verter are derived to assess the stability of the cascaded system. The effects of the LC filter parameters on the stability of the LC-DAB3 converter are elucidated. Finally, simulation results are presented to validate the imped-ance model and stability analysis of the LC-DAB3 converter.
