This paper provides a systematic survey on the topology morphing control techniques used in the galvanically isolated dc-dc converters. Existing techniques are broadly categorized based on the part where a converter changes its topology: at the input side, at the output side, and the advanced techniques that cannot be categorized in the first two groups. The techniques span from the simple reconfiguration between the full-and half-bridge switching cells similar to the conventional power supplies with universal ac input to the advanced multi-track topology and reconfigurable resonant tanks. In addition, the described variety of application examples proves the wide application range and versatility of the topology morphing control. These include fault tolerance, efficiency curve flattening, input voltage range extension, and other properties. Hence, this article provides a single comprehensive source for researchers and engineers willing to enter the topic of topology morphing control.INDEX TERMS Galvanically isolated DC-DC power converter, topology morphing control, series resonant converters.

“…In addition, the service life of SBs is limited by the depletion of active species on the electrodes which takes much shorter time than the common service life of composite structures in aircraft, making them not economical for long-term applications. Despite the lower energy density of SDCs than SSCs and SBs, the broader working voltage allowed SDCs to be used in UAVs, moreelectric-aircraft, and military aircraft, in which the most frequently applied voltages onboard ranged from 115 to 540 V (Wheeler and Bozhko, 2014;Alexander et al, 2018). In this case, there was no need to connect SDCs in series, resulting in a lower equivalent capacitance to efficiently provide sufficient voltage for onboard applications.…”

Structural energy storage composites, which combine energy storage capability with load-carrying function, are receiving increasing attention for potential use in portable electronics, electric vehicles, and aircraft structures to store electrical energy in replace of traditional electrochemical energy storage devices. The integration of energy storage ability into mechanically strong carbon fibre reinforced polymer composite is promising in reducing the weight and volume while providing additional functions, ultimately leading to energy-efficient systems. In this review, the key designs and strategies to reconcile the trade-off between mechanical properties and energy storage performances of structural dielectric capacitors, a typical type of structural energy storage composites, are highlighted. Opportunities and challenges are also discussed for the further development of structural energy storage composites for aviation applications.

“…In their study, Alexander et al [26] made an analysis of different vehicles EPSs and their evolution in the last years, to make a prediction about future MEAs architectures characteristics such as, feasible voltage levels or equipment ratings. The research concludes that few key factors like energy density, weigh, propulsion systems and EPSs' architectures will be the main bottle necks to achieve the goals stated to the MEA.…”

Aircraft manufacturers aim to decrease the fuel consumption based on reducing weight and increasing the subsystems efficiency. Hence, the Electric Power System (EPS) acquires great relevance because it must be efficient and lightweight. Any change in the EPS must not affect the aircraft's electrical safety, which under a traditional decentralized EPS strategy is ensured by redundancy. Recently, several decentralized EPS strategies based on the introduction of multi-port power converters have arisen. Such strategies meet the established safety goals since the aforementioned devices make possible to recalculate the path to continue powering the loads in case of failure. However, the literature does not address how to connect such multi-port power converters. The main contribution of this paper is to present a low-complexity algorithm that minimizing the redundancy of wiring, provides a fault-tolerant power transmission network. This is done under a decentralized EPS strategy where multi-port power converters are used. The proposed strategy is evaluated on a Boeing 787 aircraft, where we compare the length of the cables both under a traditional decentralized network configuration (where the redundancy option is used to ensure the safety of operation) and in the network provided by our algorithm. A saving of 66.6% is obtained.
