Abstract

The sensitivity analysis of a circuit reflects the robustness of this circuit to the relevant parameters. This paper investigates the sensitivity of input impedance of DAB converter, which is widely adopted in solid-state transformer (SST) and dc microgrid on more electric aircraft (MEA). In this paper, an improved impedance-based small-signal averaged model is developed to carry out the sensitivity analysis. Bode plots will be used as main analysis tool. The small signal model is compared to a complete switching model to confirm the validity of the proposed approach.
