  • Novel ac winding resistance model of integrated magnetics in switched-mode power supply

    Integrated magnetics has been popularly used to improve the power density, but the winding loss mechanism becomes more complex and hard to understand for its versatile magnetic functions. Therefore, a novel ac winding resistance model of integrated magnetics in switched-mode power supply is presented in this paper. It will be more intuitive and suitable to reveal the winding loss mechanism of the integrated magnetics which have both transformer and inductor functions. The model is illustrated with the integrated magnetics in forward- type converter and the coupled inductor in voltage regulator. With the understanding of the proposed resistance model, the measures to reduce the ac winding loss of integrated transformer can be taken by balancing the transformer component winding loss and the inductor component winding loss.

  • Optimization algorithms for magnetics and their parallelizability

    Parallelization of optimization routines is now increasingly resorted to, because of the heavy computation associated with the optimization of electromagnetic products in the process of their design. This paper evaluated the possibilities for parallelization in electromagnetic product design. The several optimization algorithms available are evaluated for their parallelizability. It is further shown that, given the present limits of technology in relation to the number of processors available on shared memory computers of parallel architecture, parallelization in electromagnetic optimization is not necessarily worth attempting at present. Thus, works of this nature, are of necessity, for the future, in readiness for that day when a new generation of parallel computer is available to us.

  • Orthogonal Winding Structures and Design for Planar Integrated Magnetics

    This paper presents a new winding design and implementation method for planar integrated magnetics (IM) to achieve high efficiency and high power density. The proposed design uses transformer and inductor windings that are orthogonal to each other in their plane orientations to minimize the capacitive coupling between them, as well as to reduce the thickness and the number of layers of the printed circuit board that hosts the windings. The orthogonal winding structures also result in lower dc resistance of the vertical winding and significantly reduce its eddy current losses. Applications of the proposed concept are demonstrated by an IM design for a 48-V-input 3.3-V-output 100-W half-bridge dc-dc converter with an integrated current-doubler rectifier. Finite-element analysis and prototype experimental results are presented to validate the proposed concept and its benefits.

  • Hysteresis Nonlinearity Modeling for Magnetics Shape Mem-ory Alloy Actuator Based on a Novel Black-box Model with Least Squares Support Vector Machines.

    With the rapid development of micro-nano manufacturing technology, there are more and more fields need nano-driven control technology, such as the high- precision positioning systems [1]. Magnetically controlled shape memory (MSM)-alloy actuators serve as the core part of high-precision positioning system on account of their high precision, large energy density, and small volume. The hysteresis nonlinearity of the MSM-alloy actuator, however, severely damages the positional accuracy of the positioning system. In order to research the hysteresis nonlinearity in the MSM-alloy actuator, hysteresis nonlinearity modeling has become a significant hot spot of research [2] [3]. The purpose of this study is to structure an excellent hysteresis nonlinearity model to capture the hysteresis nonlinearity in MSM-alloy actuators. The criterion for evaluating modeling performance is that the established hysteresis model can embody the actual characteristic of the actuator. In this study, a novel black-box model composed of the hysteresis-like structure and a nonlinear function is proposed to capture the hysteresis nonlinearity of the MSM-alloy actuator. The proposed black-box hysteresis nonlinearity modeling approach has the advantages of requiring no prior knowledge and internal physical mechanism. The hysteresis-like structure solves the multi-value mapping problem and accurately depicts the major and minor hysteresis loops of the MSM-alloy actuator. The nonlinear function represents the nonlinearity part of the MSM-alloy actuator, which is identified using least squares support vector machines (LS-SVM) on account of its strong approximation capability, high generalization ability, less parameters, and great computing power. The schematic diagram of black-box model is shown in Fig. 1. u(k) is the input current at k time, y(k) is the output displacement at k time, F[·] is the nonlinear function, Hu[·] is the hysteresis-like part of the black-box model. In the procedure of modeling, u(k) and y(k) are the input values of hysteresis-like part; u(k), y(k), and Hu[·] are the input values of nonlinear function, which is obtained by the LS-SVM. To certify the effectiveness of the black-box model, the simulations are implemented using the obtained experimental data. The simulations show that the modeling error rate of the novel black-box model based on the LS-SVM is 1.37%, which is improved 73.97% in compared with the results in [4]. It is obvious that the modeling precision of the proposed hysteresis model is within the allowable range. The simulation results are shown in Fig.2. The blue solid line is the obtained experimental data, and the red dotted line is the output of the proposed black-box model. As shown in Fig.2(a), the proposed black-box model based on the LS-SVM can accurately describe the major and minor hysteresis loops of the MSM-alloy actuator. The modeling error curve is shown in Fig.2(b). In the future, the proposed black-box model can lay a foundation for designing an adaptive controller to eliminate the hysteresis nonlinearity in the MSM-alloy actuator.

  • Advanced constitutive laws for computational magnetics: The case of magneto-mechanical behaviour.

    Summary form only given. Ferromagnetic materials in electromagnetic devices are subjected to multiaxial stress states. Stress significantly affects the material behaviour, and appropriate modelling tools are required to describe this coupling effect. Multiscale approaches for magneto-elastic behaviour can provide a useful description of the complex interaction between magneto- mechanical loading and material response. However, these models are not easily implementable into numerical simulations. This paper gives a brief overview of different strategies to extract information from multiscale approaches so as to use them in standard numerical tools for the design of electromagnetic devices. It is known for long that mechanical stress state significantly influences the magnetic and magneto-mechanical behaviour of ferromagnetic materials [1]. The different stages required in the manufacturing of electrical machines and electromagnetic devices, as well as the operational conditions, generate a variety of mechanical stress states in the ferromagnetic materials used in their fabrication. These mechanical loadings usually have a detrimental effect on the material behaviour and hence on the device performance [2 - 4]. It is then highly desirable that the designer of electromagnetic devices can have access to constitutive equations representative for the magneto-mechanical behaviour of ferromagnetic materials. The stress being described by a second order tensor (six independent components), and the magnetic field by a vector (three independent components), it is easy to understand that the possible combinations for the magneto-mechanical loading are huge. Many experimental and numerical studies are restricted to 1D configurations considering uniaxial stress (usually tensile) applied in the direction parallel to the magnetic field. Although these studies are very useful to explore the mechanisms of magneto-mechanical coupling, they obviously need to be generalised in order to cover the practical configurations encountered in most real devices. The problem seems too complex to be described by macroscopic phenomenological approaches, as often used in the modelling of - uncoupled - magnetic behaviour. A variety of approaches have been developed to describe and understand magneto-mechanical coupling effects, based on different levels of approximations. Among them, multiscale approaches (MSA [5 - 11]) appear particularly promising to capture the complexity of magneto-elastic behaviour. These approaches are based on an energetic description of the magneto-elastic equilibrium at the magnetic domain scale combined to a statistic description of the average magnetic domain distribution. A main strength of MSA is that they can naturally deal with heterogeneous and anisotropic materials. They also naturally introduce the multiaxiality of magneto-mechanical loadings (3D stress state and any relative orientation between stress and magnetic field). Some of the MSA can also consider hysteresis effects. However MSA remain usually too complex to be easily implemented into numerical analysis tools for the design of electromagnetic systems. Hence modelling strategies are required to take benefit from the output of MSA while keeping the numerical burden acceptable. A first idea is to use MSA as a “numerical testing machine” and consider it as a tool to identify the material parameters of macroscopic models. Indeed, macroscopic constitutive models, notably those based on thermodynamic approaches [12 - 15], are capable of tackling the multiaxility of magneto- mechanical effects. However they are more reliable if the modelling parameters are obtained from more complex configurations than simple uniaxial magneto- elastic tests. An option is to develop multiaxial experimental setups [16 - 19], but the use of MSA is an alternative path. The modelling parameters of MSA can usually be identified on simple experimental tests due to their univocal physical meaning. MSA can then be used to perform “numerical tests” in any loading condition suitable for the identification of macroscopic model parameters. Another strategy is to derive simplified models from full MSA, usually neglecting the effects of material heterogeneity [20 - 22]. The multiaxial feature of MSA is preserved, and the constitutive equations can incorporate anisotropy [22], [23] or hysteresis effects [21], [24]. Such approaches have been shown to be efficient to describe the behaviour of simple test structures [25], transformers [22], [26] or electrical machines under magneto-mechanical loading [23], [24]. The simplest - but also less accurate - strategy is probably to use the concept of equivalent stress [27], [28] or equivalent strain [29]. An equivalent stress is a uniaxial stress that - applied in the direction parallel to the magnetic field - would have the same effect as the real multiaxial stress existing in the structure. Heterogeneity and initial anisotropy effects are neglected, but it is a simplified way to take into account the multiaxiality of stress in electromagnetic structures without developing fully multiaxial magneto-mechanical numerical tools. This approach has been applied successfully to evaluate the potentiality of smart materials to perform flux weakening in electrical machines [30] or to analyse the effect of stress on the losses in electrical machines [31].

  • Anomalous shift of magnetic resonance line in disordered and noncollinear magnetics

    It is established that anomalous shift of magnetic resonance line in spin glasses is a general feature of noncollinear magnetics, and it is observed in helical antiferromagnetics too. The shift appears with appearing of a noncollinear magnetic short-range order. A nonuniform spin precession is excited in noncollinear magnetics. An effective exchange field acts on a spin under nonuniform precession. Using hydrodynamic theory of spin waves in spin glasses, it is shown that the value of the shift may be of the order of the resonance field, if a certain parameter, characterizing the degree of noncollinearity of the spin structure, is of the order of unity.<<ETX>>
