“…In order to ensure that the buck converter is stable when the external capacitive load C e is added to the output bus, the value off c should be greater than the new resonant frequency f r , given by (5), to ensure that the approximations are valid and the phase margin is high enough.…”

Abstract-DC-Power Distribution Systems require DC-DC converters to interface all their elements. These converters should provide a high power quality and be efficient, compact and inexpensive. Furthermore, the characteristics of the loads and sources connected to these converters are not known beforehand and may change widely (there is no regulation about the DC loads, such as IEC61000-3-2 in AC grids). As a consequence, the design procedure is neither standard nor obvious. This work proposes an optimized design procedure for any Bus Provider in a DC-Power Distribution System. It is based on models, hence extensible to different Bus-Provider topologies, and takes into account the main issues in DC-Power Distribution Systems, especially the design conditions imposed by the wide variety of loads, or even sources, which may be connected to the output bus. Experimental results obtained from three designs show a close match with the analytical models and verify that the proposed procedure minimizes converter losses and complies with the requirements.

“…Moreover, Starter Generator (SG) systems [6], [24]- [28], together with their Electrical Control Unit (ECU) are able to provide the required power to start the aircraft engines, and generate additional power during flight, on the HVDC or LVDC network. As shown in Fig.1, an isolated, bidirectional DC/DC converter has to be included in the system in order to provide an active interface between the two DC networks [29], [30]. The converter must be designed to provide high power density and high efficiency, to be integrated in the aircraft structure with minimum impact on volume, weight and heat management.…”

Abstract-High performance power conversion equipment is currently gaining an increasing interest for aircraft applications. In particular, isolated bidirectional DC/DC converters are often proposed for modern HVDC aircraft distribution systems. For such reason an evaluation of several isolated DC/DC converter topology is carried out considering the proposed application, interfacing a 270V DC network with a 28V DC network. A trade off evaluation has been carried out for three different topologies and an experimental prototype has been manufactured for the selected conversion architecture. Simulation and experimental results are provided in order to validate the trade off and the design of the proposed converter.

“…In the literature, DC-based energy distribution systems have been discussed for more electric aircraft (MEA) [4], electric/hybrid electric vehicles (HEVs) [5,6], all electric ships (AESs) [7], telecom applications [8,9] and for commercial and residential services [10,11]. The active nature of power agreement of the results demonstrates that the non-linear behavioral modeling approach is able to predict the transient as well as the steady responses of the modeled systems with high accuracy.…”

Abstract:In modern distributed energy systems (DES), focus is shifting from the conventional centralized approach towards distributed architectures. However, modeling and analysis of these systems is more complex, as it involves the interface of multiple energy sources with many different type of loads through power electronics converters. The integration of power electronics converters allows distributed renewable energy sources to become part of modern electronics power distribution systems (EPDS). It will also facilitate the ongoing research towards DC-based DES which is mostly composed of commercial DC-DC converters whose internal structure and parameters are unknown. For the system level analysis, the behavioral modeling technique is the only choice. Since most power electronics converters are non-linear systems and linear models can't model their dynamics to a desired level of accuracy, hence non-linear modeling is required for accurate modeling. The non-linear modeling approach presented here aims to develop behavioral models that can predict the response of the system over the entire operating range. In this work, either a lookup table or a polytopic structure-based modeling technique is used. The technique is further applied to cascade and parallel connected converters, being two DES scenarios. First the procedure is verified via application to switching models in a simulation and then validated for commercial converters via experiments. The results show that the developed behavioral models accurately predict both the transient and steady state response.
