“…This is well discussed in many publications including [10], [21], [22], [22], here we just notice that state-of-the-art technology considers high-voltage (230V) variable frequency (360…900Hz) ac primary distribution or high-voltage dc distribution (270Vdc, ±270Vdc or 540Vdc). An example of hybrid ac/dc MEA EPS architecture is those studies within EU FP6 project MOET [8], [23], [24] and illustrated in Figure 2 and described in details in [25].…”

“…Building MEA EPS using "PECs layer" with multiple smaller identical converters leads to the idea of flexible architecture based on modular PEC, as illustrated by Figure 5 [23], [24]. Here, each "small" PEC called "cell" (bidirectional DC/DC) [8], [23], [24] can connect any primary bus to any secondary. No power interruption happens in case of cell fault, cells can operate in parallel with others (number of paralleled cells depends on loading), and significant weight and volume benefits can be achieved since each cell is a small and modular LRU-type unit.…”

This paper presents an overview of technology related to on-board microgrids for the More Electric Aircraft. All aircraft use an isolated system, where security of supply and power density represent the main requirements. Different distribution systems (AC and DC) and voltage levels coexist, and power converters have the central role in connecting them with high reliability and high power density. Ensuring the safety of supply with a limited redundancy is one of the targets of the system design, since it allows increasing the power density. This main challenge is often tackled with proper load management and advanced control strategies, as highlighted in this paper.

“…The optimization procedure in this work is based on fully analytical modelling and consists of three layers, as proposed in [12]: First, the converter current waveforms are analyzed and key variables, such as for example RMS or ripple currents, are derived. Based on these, an analytical loss model of both active and passive components is developed.…”

This paper presents a computationally efficient design algorithm for a DC/DC converter, optimized for power density. Interleaving and series-connecting of several converter cells is included in the analysis. The choice of the converter design parameters, such as the semiconductor devices or the number of interleaved converter cells may have unpredictable impacts on the resulting power density. Therefore, fully analytical models of the operating waveforms, the converter losses and also the converter weight are introduced. Using those models, an algorithm is developed to optimize a 2 kW DC/DC converter for an aircraft supercapacitors energy storage system.

“…While it is a complex and application‐specific question, this paper tackles the issue from the perspective of power loss associated with the switching devices. Unlike other cutting‐edge power converter optimisation methods [11], there is a focus on the creation of a practical method, while still minimising loss in model precision.…”

Focusing on cascaded H-bridge converters for grid-tie battery energy storage, a practical, analytical method is derived to evaluate the switching-associated power loss in multilevel converters, evaluated from a number of sources of loss. This new method is then used to find performance trends in the use of converters of increasing order over a range of switching frequencies. This includes an experimental analysis into predicting the performance of MOSFET body diodes. Authors' analysis with this model shows that a multilevel converter can have lower losses than the equivalent single-bridge, three-level converter, particularly at higher switching frequencies, due to the availability of suitable switching devices. It also has interesting implications for enabling the use of cutting-edge non-silicon power switching devices to further improve potential efficiencies.
