Permanent Magnet Synchronous Motors (PMSM) are known to be preferred over other motors in electric vehicle (EV) application. However, due to over-dependence of expensive rare-earth magnets in these motors, lookout for alternate motors is on the anvil. In this paper, an optimized rotor design of Synchronous Reluctance Motor (SynRM) that is devoid of rare-earth materials is proposed in order to demonstrate its suitability in the EV category. Firstly, an analytical design method to determine the dimension of the stator and rotor structure of the SynRM is introduced. Without altering the stator design, an optimized design of rotor structure using the unit-less variables is proposed in this paper with the dual aim of maximizing the electromagnetic torque of the SynRM and minimizing torque ripple in it. Finite element analysis (FEA) is used to verify the analytical design and optimization of the rotor structure. The results of the SynRM design and optimization are presented to showcase the effectiveness of the envisaged design methodology.

This paper describes the research for implementing a commercial giant magnetoresistive (GMR) sensor for detection of magnetic nanoparticles with potential applications in lab on a chip (LOC) device or for analysis of waste water. Micromagnetic simulations are performed to illustrate the behaviour of the detection system. The experimental setup focuses on the detection of polyethylene glycol (PEG6000) functionalized magnetic nanoparticles, commonly used in biosensors and LOC devices. Practical solutions for improving the GMR sensor measurement setup are detailed and discussed. From the experimental measurements we are able to detect a mass approximately 1.20 μg of pure maghemite cores which corresponds to a magnetic moment of approximately 9.098∙10-5 emu for a signal variation of 0.035 V. (in this case, a detection sensitivity of about 75.81 emu/g). Emphasis is placed on advantages in terms of setup sensitivity, flexibility and integration.

This paper presents a fully electric propulsion system with supercapacitors (SC) as the only power storage element, for a quick charge in the minibus stations. A bidirectional DC-DC Converter is used, as the interface between the SC and the drive. The traction is implemented by a single interior permanent magnet synchronous motor (IPMSM), fed by an inverter, with vector control strategy. Analytical description and extended simulation results for a synthetic and a measured urban driving cycle profile are presented, confirming the initial theoretical considerations and proposed technical solutions.

The paper discusses three state-space models of a low-power off-the-shelf induction machine. Each of them considers the same set of conductor distribution harmonics consisting of orders 1 and 17. This specific configuration is interesting as it generates a principal slot harmonic (PSH) in the stator currents as well as torque oscillations. The three models are of order 6 and differ from each other with respect to the state variables involved and the reference frame in which the model equations are expressed.The models are evaluated on the basis of their complexity, numerical accuracy and potential for use in practical applications. In this regard, a model variant with stator currents and rotor fluxes as state variables appears particularly promising for use in drive control, for instance to extend existing field oriented or predictive control schemes.

Photovoltaic cells are the best known devices to convert solar energy into useful electrical energy, however, in the most efficient multijunction solar cells, more than half of the input solar energy converts into heat and wastes. In this experimental investigation, a thermoelectric generator, as highly reliable solid-state device, and a box containing phase change material are integrated to a concentrated triple junction solar cell in order to enhance the utilization of the solar energy. The triple junction solar cell and the thermoelectric generator are characterized by measuring the I-V-P under different solar concentrations. In order to evaluate the impact of using PCM, the obtained performance of the hybrid system and the short circuit current, open circuit voltage and maximum power for its two components are compared in steady state and transient regimes with the hybrid system without the PCM. The results indicate that enhancement of the concentration ratio has opposite impact on the efficiency of the thermoelectric generator and the triple junction solar cell. Furthermore, the phase change material box has a more considerable impact on the power generated by the thermoelectric generator than the triple junction solar cell for both regimes.

The steep voltage slopes of today’s wide-bandgap (WBG), fast-switching power semiconductors — like SiC and GaN — lead amongst other challenges to reflection on long cables and thereby overvoltage at inductive loads. To enable the use of these inverters with motors without specially reinforced insulation the voltage slopes need to be slowed down. This article presents a new low-loss countermeasure, which involves the parallel connection of two half-bridges via an interphase transformer. For this one half-bridge is delayed relative to the other one by a delay tuned to a resonant circuit. Undesired DC components in the cross-current of the interphase transformer occur due to non-idealities in the voltage symmetry. The subsequent DC magnetization ultimately can cause the core to saturate. The paper describes the effects due to inaccurate timings and the aspects to keep in mind when dimensioning the magnetic core. Also, this article describes an approach to deal with the undesired current components using a closed-loop control. For that, a special differential-mode shunt is used which enables a dedicated measurement of the cross-current mean value and mitigates the influence of the switching frequency. Finally, the controller concept is presented. The controller is implemented and verified on a 500 kVA SiC inverter test bench.

Surface permanent magnet machines gain more and more attention over recent years due to their high power density and high efficiency. This paper compares the Vernier machine and surface permanent magnet synchronous machine in electromagnetic structure, operating principle, and steady-state performances. FEA results are used to verify the analytical equations for comparing Vernier machine and SPM machine performance, with the exact dimensions, in terms of back-EMF, cogging torque, torque generation capability, and torque ripple. Moreover, the machine's back-EMF and torque performances regarding magnet thickness show that the Vernier machine utilizes magnets better than the surface PM machine.

Non-thermal plasma treatment technologies using air as gas to oxidize at atmospheric conditions applied on polyethylene terephthalate (PET) film lead to modification of chemical and physical surface properties without altering the internal properties. The oxidation degree and the surface modifications during the ageing were studied through sessile drop method using a goniometer and surface tension was measured by an Arcotest pink ink. The goal is to assess the effect of a discharge from a barrier discharge reactor (DBD) on two PET surfaces in order to increase the hydrophilic proprieties on these surfaces. This work was performed using a DBD reactor with generated electric discharge at 20 kHz frequency between two circular plane electrodes placed at a gap of 7 mm one from each other, powered by an AC high voltage power supply. The DBD treatment effect is highlighted through smaller values of water contact angles and better surface tension.

Due to the increased interest in electric vehicle (EV) technologies and the cost reduction of photovoltaic systems, industrial development of battery charging stations for electric vehicles based on solar energy has started. Although it is convenient to charge EVs at night, when there is less electricity consumption, there will always be consumers who prefer or need to charge their EV during daytime and even during peak hours. In this paper, an EV charging station integrating renewable energy in the form of solar energy is proposed and analyzed. Using a local battery pack, the charging station allows semi-fast and fast charging and can be installed in individual homes and apartment buildings, where the maximum power delivered by the grid is limited to 3.6kW. The charging station uses converters widely available on the market. A simulation model for this charging station is developed and various distinct operation modes are presented, validating the correct operation of the entire system.
