This paper develops a method to analyse robust stability of a generic electrical power system for safe-critical applications over all operating conditions. Standard methods can guaranty stability under nominal conditions but do not take into account any uncertainties of the model. In this work, stability is assessed by using a Structural Singular Value concept that can provide a measure of stability robustness of a Linear Fractional Transformation (LFT)-based linear system with structured parametric uncertainties. In line with this, the first step was to develop a parameter-dependent linear time-invariant state-space model of the system that is valid for all operating conditions. The model was obtained by symbolic linearisation of the system non-linear model and was further extended to include structured parametric uncertainties of the system. The developed approach was successfully applied to determine the critical destabilising torque of a 4 kW permanent magnet motor drive over the defined range of operating conditions. Matlab robust stability toolbox was used for this analysis. The results were validated against simulation and experimental data.

Voltage stability is a focal issue in every shipboard power system, where strict requirements (e.g. specified by STANAG 1008, classification rules, IEEE and IEC standards) are defined to guarantee safe operation under various operating conditions. This work proposes a low-voltage DC (LVDC) shipboard power system design and evaluates its voltage stability performance by comparing it with a standard low-voltage AC (LVAC) design. In order to evaluate the resulting transient performance, two different models are implemented with the aid of numerical simulation toolbox SimPowerSystems, working under the commercial software Matlab/Simulink. Voltage transients in LVAC and LVDC systems are simulated, resulting from an identical disturbance, i.e. disconnection of one of the Diesel Generators. From the observed transient responses, two different integral indices are used to assess the degree of system stability for both the LVAC and LVDC configurations. The indices considered are: Integral Absolute Error and Integral Time Absolute Error. The smaller values of the integral indices show the excellent capability of DC technology to maintain voltage stability following typical disturbances.

An increasing interest is currently verified in DC power distribution systems for the More-Electric-Aircrafts (MEA). DC power distribution enables a more efficient use of the generated power and aids in paralleling and load sharing. Transformer Rectifier Units (TRU) and Autotransformer Rectifier Units (ATRU), commonly employed to date, are heavy to be deployed in a MEA because the power to be handled is much higher than in a conventional aircraft. This is particularly applicable in case variable frequency generators are used since it is not possible to synchronize their outputs directly. In this paper an advanced active rectifier is proposed for MEA applications. It is based on a Single-Star Bridge Cells Modular Multilevel Cascade Converter (SSBC MMCC) combined with Dual Active Bridge (DAB) DC/DC converters in order to create a DC Multibus. The performances of the system are analyzed considering different load configurations and variable frequency operation. Results confirm the validity of the proposed solution and the robustness of the control system in different operating conditions.

The operation of a high voltage gain boost dc-dc converter is investigated in this paper. This investigation consists of the calculation the critical inductance between continuous conduction mode (CCM), discontinuous conduction mode (DCM), complete inductor supply mode (CISM) and incomplete inductor supply mode (IISM). Then, the switches peak current is calculated in DCM and CCM. Moreover, the effect of the electrical parameters in the peak current of power switches is investigated and a method to minimize the output voltage ripple (OVR) by considering minimum switching current stress and size of filter is proposed. Finally, in order to verify the presented theoretical issues, the simulation results in EMTDC/PSCAD software program are used.

Dynamic wireless charging is the process of supplying electrically driven vehicles along their driving path with electric energy via a wireless energy transfer system. To increase the range of electric vehicles, a dynamic charging lane is to be installed on a highway. With regard to the amount of power needed, supply of electric energy is a major concern. High-power overhead lines or cables are not regularly available. In many cases, electrified railway lines run in parallel to or cross motorways. Consequently, the railway energy supply system can be used to feed the wireless energy transfer system. This paper introduces a concept of supplying the wireless power system and appropriate magnetic layouts are selected according to a comparison of different magnetic design approaches. A companion paper introduces and discusses concepts for the link between the railway grid and the wireless charging system.

The increase in installed power onboard ships and the adoption of electric propulsion led to the need of a rather complex power system. The so-called Integrated Power System (IPS) feeds all the ship loads, integrating into a single entity the functions of generation, regulation, distribution and utilization of the electric power. The integration, thus being a powerful tool to increase vessel's performance, reliability and efficiency, permits also the propagation of disturbances to all the users fed by the IPS. Being Power Quality a primary need for the loads (and especially for some particular military ones) it is needed an assessment of the disturbances that can occur in the power system, both in terms of voltage and frequency transients and in terms of harmonic distortion. In this paper is presented a measurement campaign to assess disturbance levels and performance of a Naval vessel.

This paper presents a design methodology for high power density converter (HPDC) operating as an AC aircraft bus provider, which presents a particular gravimetric power density challenge. High power rating 3-phase AC-DC converter design with weight minimization is elaborated. By considering sizing of major converter parts that contribute to total converter weight, optimal switching frequency to yield highest power density is evaluated. The design evaluation for 50 kW converter with SiC power modules yields overall gravimetric power density of 3.76-5.35 kW/kg at optimal switching frequency of 60 kHz and volumetric power density of 7.04-7.38 kW/l respectively.

In this paper, a bidirectional, non-isolated dc-dc converter with several interleaved phases of multilevel modules for automotive power systems is presented. Instead of using a 2-level stage with short-circuit protection elements, a 3-level module in a multiphase structure is proposed to achieve improved fault-tolerance. The dimensioning of the required flying capacitor for multilevel dc-dc converters is described. Further benefits like ripple reduction, automatic fault current limitation and enhanced efficiency are achieved. Moreover, the control strategy for normal operation including the stability of the flying capacitor voltage as well as reconfiguration after failure for degraded operation are explained.

Silicon (Si) IGBTs are widely used in railway traction converters. In the near future, Silicon Carbide (SiC) technology will push the limits of switching devices in three directions: higher blocking voltage, higher operating temperature and higher switching speed. The first SiC MOSFET modules are available on the market and look promising. Although they are still limited in breakdown voltage, these wideband-gap components should improve traction-chain efficiency. Particularly, a significant reduction in the switching losses is expected which should lead to improvements in power-weight ratios. Nevertheless, because of the high switching speed and the high current levels required by traction applications, the implementation of these new modules is critical. In this paper, the authors focus on the parallel connection of Dual-SiC MOSFET modules. The key points are underlined and an original approach is proposed to design the bus-bar and the gate drive circuit. Experimental results performed on an Opposition Method test-bench, valid the good operation of three Dual-SiC MOSFET modules in parallel.

Permanent Magnet (PM) machines are increasingly being used in safety critical systems in aerospace and automotive applications. In such applications, reliability and availability are key concerns. Numerous works have been presented in literature which take into account both system reliability and availability in the event of single fault within the PM machine. This paper mainly focuses on a turn Short-Circuit (SC) fault and presents a systematic review on proposed methodologies to accommodate such faults. The possible methods to reduce the likelihood of the winding SC fault, and the available fault mitigation techniques related to such faults, are reviewed. It is shown that there is a tradeoff involved between reliability and the machines' performance.
