Abstract: The electrical power distribution system (EPDS) of the more electric aircraft (MEA) is a fundamental component that needs to be efficient and resilient. The commonly considered architectures feature separate buses to achieve separation between different subsections of the EPDS. Although effective, this implies an over design, since all sub-sections are sized for the local worst-case scenarios. In the MEA concept, multi-port converters could connect the whole EPDS while guaranteeing the galvanic isolation betwe… Show more

“…It can be seen that as the proportion of the LPR's power increases, the peak magnitude of the source impedance at the low-frequency region will decrease. According to the Middlebrook Criterion, reduction in the magnitude of the source subsystem impedance indicates that the system tends to be more stable [19], [20].…”

“…Other alternatives can be found in the literature, such as the generalized input impedance model [23]. However, the behavioural model obtained from averaging the power flow among different ports is the most used approach.…”

“…The output impedance, including that of the controller, can be obtained as (20) using (18) and (19). The source converter loop gain is expressed as (18), and the small-signal open-loop transfer function of the output voltage control is obtained by (19):…”

“…The Passivity-Based stability criterion determines stability by reducing the source and load subsystem to a single port network. Among these various stability determination methods, to apply Gain Margin Phase Margin, it is difficult to apply to a system because it is necessary to know both the gain and phase margin of each converter constituting the system [18]. Since the Passivity-Based Stability Criterion combines the source and load subsystems to analyze stability, it is hard to understand the interactions between the source and load subsystems.…”
