  • Impedance-based models are commonly used to perform system-level stability analysis of distributed power systems. In this paper, a new impedance identification procedure for three-phase balanced voltage source inverters voltage source inverters (VSIs) is proposed. This procedure is based on the transient response of the inverter to simple passive load step tests. Transfer function models are obtained from the transient response by means of a well-established and easy to use identification algorithm. The performance of the proposal is validated through both simulation and experimental results obtained on VSIs for aircraft applications.
