Full textThis thesis deals with electric micro-generation and micro-energy management. The developed micro-generator is a millimetre-scale, planar, axial-flux, ironless, permanent magnet, synchronous machine compatible with fast rotating MEMS turbines. Established multiphysical model enables the magnetic generator performance estimation in dependence on its operating point and geometry. A 8mm diameter magnetic micro-generator has been successfully tested to speeds up to 380 000 rpm ; at this speed it generates 5W with an electrical efficiency of 57%. A prototype of a fully integrated micro-turbo-generator generated about 15mV at 60000 rpm. Low power AC/DC micro converters for low voltage micro generators were also studied. A three-phase, high efficiency, low voltage, low power and fully autonomous micro rectifier was monolithically integrated in the CMas 0,35 μm technology. The tests on the μ-rectifier cou pied to the magnetic generator confirmed its functionality and high efficiency

Full textThis work focuses on the Modelling and the design optimization of an electrical motor-generator integrated in an electromagnetic coupler for automotive applications. A study of electric motor-generators and electromagnetic couplers used mainly in traction systems proposed in literature is presented. For the application witch is the aim of "Defontaine" company we proposed and studied two systems operating on the basis of two different principles. The first system adopts the principle of transmitting torque by friction and uses an axial flux homopolar motor-generator. The second is based on a system of dog clutch ; the motor-generator in this case is a permanents magnets synchronous machine. Both of the two topologies, axial and radial machines are studied. With the aim of design and optimization of the three machines, electromagnetic and thermal models are presented. These models are then coupled with a stochastic particle swarm optimization algorithm. For the particular case of the radial permanent magnet machine, we have developed an original method of optimization based on the direct calculation of the optimal parameters. This method is then used to study the case of the high speed machines. A test bench has been especially designed to validate the developed models and the two principles of electromagnetic couplers

Full textThe constant miniaturization of electronic systems has driven the development of new generations of ultra-compact power sources that could surpass the performance of conventional batteries. MEMS-based heat-engine-driven devices are very attractive in such small power systems. The focus of this research is to develop electromagnetic microsystems capable of generating electrical power, and driven by either cold or hot gases. First, rotary permanent-magnet microgenerators are developed for watt-level applications and compatibility with heat engines. Further miniaturization of such devices is also presented. Next, small-scale fluidic packages are coupled with these microgenerators. Polymer-based microturbines are engineered for air-driven micropower sources, and silicon-based gas-bearing microgenerators are developed for compatibility with micro heat engines. Finally, a fuel-driven power generator is presented, and consists of a MEMS-fabricated pulsejet and its electrical generator. The device, powered by a source of hydrogen fuel, demonstrates chemical-to-electrical power conversion

Full textThe design of a micro-wind energy conversion system represents the core of this study. The attention is derived towards the brushless DC permanent magnet generator with outer rotor configuration and trapezoidal induced back-EMF voltages. The global aim of the thesis is represented by the attempt of determining the optimal geometrical and electrical design parameters of the BLDCPM generator that give the minimum total power losses in the system, over long-term wind speed cycle operation and thereby increasing the efficiency of the overall system. In advance to the optimization, an adapted simulation model needs to be developed in terms of results accuracy and simulation time. This is done in the first part of the thesis by determining the modeling level, as well as the design variables of each component of the system. As the optimization appeals to an algorithm for the design process, the reduction of the simulation time has been investigated in the third and fourth part of the thesis by developing a suitable method that allows the integration and exploitation of the available data from the wind-speed profile when determining the totality of the power losses in the system. Afterwards, the optimization methodology is presented along with the optimum results obtained, as well as comparison of several input/output parameters. Finally, experimental tests are also carried out on a reference BLDCPM machine prototype in order to verify its electronic commutation and control technique

Full textThis Ph.D. dissertation presents a multidisciplinary optimum design methodology to permanent magnet synchronous generators applied to wind power. Such a methodology considers the electrical, the geometrical, the thermal, the electronic, the mechanical and the economical behaviors of the wind turbine. The wind occurrence curve, modelled by a statistical density function, is also take into account by the proposed design methodology. Considering this curve in the optimal design allows to calculate the amount of energy produced by the wind turbine, which operates under variable speed and power by the influence of the actual wind speed. The proposal of using the optimization in the design is to enhances the competitiveness of wind power by designing a generator with a good relation between its cost and its capacity to generate energy. Several studies are addressed to electrical machines optimum design related to wind power, however, few have presented a method able to estimate the wind turbine energy generation, which is mandatory to obtain a cost-effective generator. Further, the electric generator in-depth multidisciplinary aspects have been considered by the proposed method in more detail than other studies found in literature. Take into consideration all these aspects results in a large optimization problem that has approximately 2000 variables, among which approximately 250 have constraints imposed on. A deterministic optimization algorithm has been chosen to deal with this problem. Such an algorithm is capable of finding the solution within few iterations and a short time thanks to the computation of the Jacobean matrix, containing the exact gradients of the model (used to describe the wind turbine behavior) outputs. The presented results explore the proposed methodology potential. The first optimal design performed minimizes the generator active material cost, presenting a significant cost reduction compared to a non-optimal generator. Next, the contradiction between the generator cost and its efficiency is analyzed and the importance of including the wind turbine energy generation into the generator design becomes evident. Using the estimated wind turbine generated energy, the generator with maximum net earnings (equal to the wind turbine energy proceeds less the generator cost) has been obtained. This generator has a good ratio between its cost and capability to generate energy. Then, sensibility analysis have been carried out to verify how the electricity price and the annual mean wind speed influence the design. Finally, two wind turbines with different diameters and rated wind speeds have been employed, considering three distinct wind profiles. These results provide the generators more suited to each wind turbine applied to each wind profile, showing that the proposed design methodology has the ability to helps choosing the wind turbine adequate to each wind farm

Full textEncouraged by the economical (decentralization of energy production) and political context (Kyoto Protocol, Buenos Aires Conference, EOLE 2010 Program), the wind energy market meets a continuous growth. Jeumont Industries, an industrial partner of this research study, has developed during the previous decade a direct drive wind generator using an original axial flux permanent magnet synchronous generator. During last decades, important technological advance was noticed in different research areas, as permanent magnets and power semiconductors. Taking into consideration these evolutions, the goal of this study is to investigate the possibility to increase the power of a direct drive wind generator using Jeumont technology. The study is based on the development of multi-physical, multi-level and multi-scale model, which properly combines finite element analysis, dynamical simulation and analytical models. The use of the numerical tools allowed finding the system configuration which better corresponds to the imposed quality criteria: an odd phase number polyphased structure having uniform distribution, which allows easier winding technique, as concentrated one. Different possible configurations of chosen structure are analytically determined, numerically analyzed and ranked. The best ones are optimized and the designer’s final option depends on the compromise to be done between the economical aspects and performances of the system
