Switched reluctance machine (SRM) has low cost and good performance in hostile environments and high temperatures. These characteristics made it suitable for applications as electric vehicle. However, its difficult control is a disadvantage for this purpose. In this paper a fuzzy control strategy for switched reluctance machine applied for an integrated started-generator is presented. The inputs are the generated power error and its variation, and the output is the switching angle of the machine drive. The results are encouraging, although they are still provisional and we have to improve the control.

This paper proposed a novel approach to calculate the iron loss under DC bias condition using modified Jiles-Atherton (JA) model. The influence of DC bias on the JA model is analyzed. The parameters in the JA model are extracted from BH loops without DC bias but they are applicable for the one under DC bias condition. Thus the modified JA model is practically convenient for iron loss prediction. Moreover, the parameter identification is fast. In addition, the influence of different magnetic induction levels and frequency is incorporated in the model. An accurate measurement system is established to measure the BH loops and iron loss. The tested results are demonstrated and compared with the predicted iron loss to verify the modified JA model.

The paper reports the main developments and results achieved so far within the EU-funded H2020 XERIC project, which is aimed at developing a new climate control system that is able to increase Battery Electric Vehicles (BEVs) autonomy thanks to its high energy efficiency. The XERIC system combines a traditional Vapor Compression Cycle (VCC) with a Liquid Desiccant Cycle (LDC), by taking advantage of an innovative component, called Three-Fluids Combined Membrane Contactor (3F-CMC). The two experimental setups arranged to test LDC alone and the overall XERIC system are presented. Then, the experimental results obtained in the first test campaign are given and discussed. Finally, the numerical tool developed in the Matlab/Simulink environment for the evaluation of the performance of the overall XERIC system is introduced and a preliminary comparison between numerical results and experimental measurements is provided.

The modern power electronics physical simulation reduces the system design time and accelerates the implementation phase. Physical simulation models on component-level, mainly for efficiency prediction, for a submodule of a 17 level cascaded H-bridge inverter are introduced and validated by measurements. The simulations are done using physical models in Simscape and LTSPICE to consider the dynamic waveform of the switch-on and switch-off of the power MOSFETs. Finally, the efficiencies of the H-bridge inverter, calculated at different operation points using physical simulations, are close to the power analyzer results.

In this paper we present a generalized geometry and design analysis to filter out the most salient parameters that have influence on the magnetic coupling coefficient and lead to a design which is more tolerant towards misalignment, such that it provides an auxiliary guiding role in system design. A parameter correlation and sensitivity analysis are performed in order to simplify the model by eliminating the variables that are less significant with regards to achieving a more tolerant design to misalignment with a higher coupling coefficient. The study is done using finite element methods, ANSYS Workbench. Analysis results and design recommendations to support decision making are obtained.

In this study, fuel economy potential of a power split hybrid configuration with 4-speed was investigated by adding the parallel mode. First, system efficiency of the power split configuration with 4-speed was investigated using network analysis. From the network analysis results, it was found that the efficiency of the target hybrid system was improved by the added 4-speed gear steps, which provides four mechanical points. To maintain the system operation at the mechanical points, a new power split-parallel architecture was proposed by adding a brake at the MG1 shaft, which provides a parallel mode instead of the power split mode. To evaluate the fuel economy potential of the proposed power split-parallel configuration, backward simulations were performed using dynamic programming by considering the drivetrain losses. From the backward simulations, it was found that the fuel economy of power split-parallel configuration with 4-speed is improved.

DC microgrids are becoming more and more popular since they are considered the next generation power systems. In the meantime, Electric Vehicles (EVs) have gained increased popularity because they can be a promising solution to the rising concerns about environmental and energy issues. Due to the attractiveness of the Vehicle to Grid (V2G) technology, the present study focuses on designing a bidirectional DC charger of an EV. The DC-DC converter used in this study is the Dual Active Bridge converter. A design methodology as well as a control strategy is proposed. The proposed charging configuration has been simulated in Matlab/Simulink. Some interesting results about the effectiveness and the dynamic response of the proposed configuration have been obtained.

Wind and solar energy have been taking the control of the renewable energy market, as costs have decreased rapidly and the threats from climate change have made clear the need to change from fossil fuels. Wave energy has been underrated all the past years. Wave energy has more potential and more advantage the other forms of renewable energy. More predictable, consistent and controllable than either wind or solar power, with the right infrastructure in place, it could be a sustainable alternative for supplying base-load power. It also has a very low impact that neither disturbs aquatic life nor spoils the coastal view that prompts so much ire from the public. The paper presents a wave power converter system. The results obtained are analyzed and the data of the simulation are presented as preliminary validation. The purpose it is to discuss different wave energy converter WEC, we will have a full simulation of each type and discuss the functioning of each one of them. The models are implemented and simulated through the applications Design Modeler, ANSYS AQWA and WEC-SIM. On the basis of the simulated results, we can conclude that generating power from the wave is quite promising for our future and will be a great addition in the renewable energy market, and will contribute to face the global climate change problem.

This study pertains to the fabrication of silicon nanowires (SiNWs) by the Metal Assisted Chemical Etching (MACE) method and their characterization. Here, silver (Ag)-metal is used as catalyst. For different deposition times of the Ag-metal, SiNWs with different heights are obtained. The optical and electrical properties of the SiNWs are analyzed and compared with those of the bulk silicon. It was found that SiNWs, obtained for 5 minutes processing, perform better than the others. They exhibit the lowest reflectance (around 5%) and the best electric conductivity.
