This paper presents a novel multi-turn solution for integrated DM-CM filter used in DC-fed motor drive system. The proposed solution is targeted for high-current and high-altitude applications by stacking multiple PCB(s) and interconnects. A ladder network is proposed to realize the multi-turn solution, while edge plating is proposed for filter grounding. A Printed Circuit Board (PCB) based Active Magneto Resistive sensor (AMR) is embedded within the PCB dielectric to measure DC side current. PCB based feedthrough connection is implemented to improve DC filter attenuation characteristics at high frequency. Challenges pertaining to partial discharge (PD) free operation, high current and grounding of the filter are discussed. The filter and enclosure are tested in a high-altitude chamber for partial discharge. The integrated AMR sensor is tested using Silicon Carbide (SiC) enabled three level inverter under open loop RL load tests. The proposed structure is highly competitive compared to the state-of-the-art technologies and is recommended for low weight requirements.

Military aircraft have always been the flag-bearers of innovative technologies to enhance performance capabilities, reduce weight, improve reliability, and advance navigation/control automation. Military aircraft such as the F-35 is designed to achieve aerial surveillance, stealth operation, and dogfighting capabilities. To achieve an optimal design, an innovative integrated subsystem design approach is adopted in F-35. This concept has resulted in a set of innovative but complex subsystems being developed and employed in military aircraft F-35. This paper focuses on exploring and mathematical modeling of the electrical power system (EPS) of F-35 powering different load types, including critical avionic loads, high-power actuators, and environmental control system loads. A flight profile showing different modes of operation is used to highlight the intermittency and power requirement in various modes. Based on this, a detailed mathematical model is simulated in MATLAB/SIMULINK®. Based on the simulation results, asymmetrical load distribution and intermittency of the electrohydrostatic actuator system (EHAS) load resulted in a power imbalance of 5% and 15.8% of line rating, respectively, is highlighted. To address 747146this concern, a modified EPS is proposed, with a triple-active bridge converter, capable of exchanging controlled bidirectional power between the two HVDC buses thereby improving dynamic balancing and operational efficiency with no extra cost and additional weight.

Electric aircraft require high performance and high reliability electric motor drivetrains. A geared electric motor drivetrain will outperform a direct drive motor drivetrain in most applications. Traditional mechanical gearing, however, has mechanical contact-based wear and failure modes that result in added maintenance costs and require an oil lubrication system. Magnetically geared motor drives are a potential technology for electric aircraft applications capable of enabling the benefits of a geared drive without the maintenance, reliability, and lubrication system cost of mechanical gears. In this paper, a topology of magnetically geared motor, an inner-stator magnetically geared motor, is explored to estimate its achievable performance for electric aircraft applications. Optimization results on the topology show that it can achieve greater than 15 Nm/kg specific torque and 96% efficiency at 100 kW of power.

The primary focus of this paper was to examine the feasibility of using a solid oxide fuel cell (SOFC) generator (fueled with low sulfur liquid hydrocarbon) as the energy source for primary power of a small aircraft. Comparison with H2-fueled, low temperature proton exchange membrane (PEM) fuel cells was also examined. A complete set of hybridized generators (SOFC + turbine + battery) system layouts were developed for short and long duration flights. Solid models and packaging concepts for the optimized SOFC solutions for both mission durations were also developed based on our prior testing data on the sub-scale.The work resulted in identifying key risks for scalability to mega-watt (MW) scale electrified aircraft propulsion (EAP). It can also be used to support certification and regulations development for electrified aircraft propulsion (EAP) systems in future work.

Recent improvements in state-of-the-art (SOA) batteries driven by the automotive sector have led to many electrified aircraft concepts choosing batteries as the preferred energy-storage method. Current SOA batteries are at the point of enabling certain hybrid and all-electric aircraft, particularly small, short range, lower speed aircraft Higher performance batteries improve aircraft range and can enable larger, higher speed aircraft. In this work, we develop specific energy projections for future electrified aircraft. The projections are developed based on examining historical commercial SOA trends as well as practical limitations of future chemistries. Accurate projections of future specific energy values are important for estimating the timeline for commercial introduction of electrified aircraft. This work estimates nominal cell level specific energies for rechargeable batteries of 489 Wh/kg by 2030, 638 Wh/kg by 2040, and 764 Wh/kg by 2050. More conservative as well as more aggressive estimates are also provided.

High performance inverters are key components in electric applications. The capacity of operation, efficiency and life cycle of inverters can be limited for magnitude of losses and external factors as ambient temperature and humidity. The liquid cooling heat sink can reduces the level of temperature of system and increases the overall eficiency of system. This paper presents an analysis and modeling of a three-phase inverter for electric vehicle applications with liquid cooled heat sink. The study of inverter switching and conduction losses is carried out for a Silicon Carbide devices. The modeling of the heat sink is developed and evaluated through Foster thermal network. The heat sink is simulated in the ANSYS software by using finite element approach. The results of heat sink system temperature are evaluated with different flow rate conditions. The dynamic analysis is performed in Typhoon Hill software with commercial SiC device parameters.

The thermal management of power electronics is a critical challenge for the successful electrification of mobility. To satisfy the strict weight and efficiency requirements realizing a highly integrated cooling system is crucial. In this context, flat-plate pulsating heat pipes are a promising technology, adding a passive thermal functionality to thin mechanical structures. To evaluate potential applications within the inverter, a numerical 3D-model based on thermal conduction is employed. The present modeling approach is derived from considerations of thermal resistances in flat-plate pulsating heat pipes adapted to well documented experiments from literature. The thermal performance of concepts utilizing the pulsating heat pipe is compared to a conventional solid design. The benefits of heat spreading to a continuous heat sink and the transfer to remote heat sinks are investigated. In addition, an innovative double-sided cooling approach is presented, which combines the benefits of traditional heat spreading with the remarkable thermal conductivity of the heat pipe from the top side. The results are highlighting the new degrees of freedom in thermal management which are enabled by flat-plate pulsating heat pipes.

In the transition to electric fleets around the world, electricity demand from electric vehicle (EV) fleets is expected to become significant in the future. Since fleet cars can display different charging characteristics than individual EVs, analyzing the charging behavior patterns of fleet cars is essential. To do so, this study first examines real EV fleet data from 724 charging events using data analytics methods. Based on this analysis, a charging behavior model is then developed to predict the realistic charging demand of an EV fleet with any number of EVs. In order to overcome the limitations of traditional probability density functions, this study utilizes Gaussian Mixture Models and Kernel distribution in developing charging behaviour models, i.e., charging start and end times, and total charging energy. The models’ behaviours are then compared in terms of goodness-of-fit (GoF) to determine the best match for the original data, in which normalised root mean squared error serving as the fitness criteria.

The increasing demand for high-quality yet low-cost electrical machines for electric and hybrid electric vehicles requires optimizing manufacturing processes across all machine elements. The needle winding technology offers the potential to meet these requirements for the production of essential components: copper windings. Thereby, the understanding of wire behavior plays a key role. In particular geometric wire bending behavior significantly influences the planning and execution of winding trajectories. Thus, building on previous work, this paper takes further steps toward a data-driven empirical approach to modeling geometric wire bending behavior. The overarching goal is to provide an efficient and comprehensive model of wire bending geometry as a function of wire tensile force and wire exit angles at the needle outlet. Spline models generated with the help of a purpose-built test bench with a dedicated image processing pipeline serve as the basis for a simplified modeling approach. The proposed model is based on circular arcs with tangential linear functions, allowing the wire bending geometry to be defined with only three parameters. Qualitative analyses of the resulting model behavior and quantitative investigations of the model errors show accurate approximation results and confirm the suitability of the developed method.

Double-stator switched reluctance machine (DSSRM) can further increase the output power of conventional SRM. In this paper, the inner stator of SRM is constructed by using the hollow part of the motor. Firstly, with the help of the SRM design method based on a database, a 16/12 traditional motor model and 16/12 outer rotor SRM model are built, and the two are combined to obtain a 16/12/16 DSSRM model. Secondly, the static characteristics of DSSRM, such as torque, flux linkage, inductance, and so on, are obtained by finite element simulation. Finally, MATLAB-Simulink and FEM are used to dynamically simulate the motor to verify the DSSRM performance.
