  • Harmonic Generation-1

    Harmonics are generated not only by nonlinear electronically controlled loads, but also by the conventional power equipment, such as transformers, motors and generators. Harmonics in transformers originate as a result of saturation, switching, high-flux densities, winding connections and grounding. It can be said that power transformers generate very low levels of harmonic currents in steady-state operation, and the harmonics are controlled by design and transformer winding connections. All commercially available harmonic analyses programs eliminate triplen harmonics on the power lines feeding the delta windings and consider the phase shifts in the transformer windings to alter the phase angle of harmonics on the primary side of the transformer. For delta connected transformers the ferroresonance can occur for less than 100 ft of cable. Power capacitor in appropriate system configurations, when applied as filters, will limit the harmonics in the power systems, by acting as a sink to the desired harmonics.

  • Nonlinear Electromagnetic Field and Its Harmonic Problems

    Harmonics are mainly generated from both the component level i.e., nonlinear magnetic or dielectric components and the circuit level, including power electronic circuits. This chapter illustrates the examples of load current waveforms with harmonics. To understand harmonic distribution in the transformer the excitation voltage and magnetic flux waveforms and associated current waveforms should be investigated. The chapter discusses the impact of harmonics on renewable energy and microgrid systems. Power electronic devices, as used for renewable energy systems and microgrids, might be able to cause harmonics. Since harmonic loading, direct current (DC) injection, voltage ripple, and voltage range of operation are key areas that influence the operation of the transformer in renewable energy and microgrid systems, the harmonic balance finite element method (HBFEM) is an effective method to analyze the harmonic problem in the transformer connected with voltage or current sources.

  • Mobility

  • HBFEM for Nonlinear Magnetic Field Problems

    This chapter discusses mainly the numerical modeling and analysis of electromagnetic fields in switching power supplies. It uses harmonic balance analysis, combined with the finite element method (FEM), to solve problems arising from non-linear, harmonic, eddy-current and power loss problems of transformers used in switching power supplies. The chapter also discusses the harmonic balance-FEM (HBFEM) model and computed results, compared with experimental results. The harmonic components of current and magnetic flux can help to accurately analyze and design the magnetic core and winding structures, and further determine the power loss and leakage flux in the magnetic system. The numerical model of voltage excitation with a nonlinear magnetic field is more accurate than conventional magnetic field-only analysis. The EM full wave solution can be obtained from HBFEM based numerical computation. To verify the HBFEM based solution, a single-phase direct current (DC)-biased switching transformer with a voltage source driven model is used.

  • Control Strategies for Power Converters

    This chapter deals with the control actions needed to keep a specific variable of the converter under control, for instance, in a motor drive system where the speed must be controlled electronically through a power converter, or in a circuit designed to correct the power factor actively. It presents some principles of the controllers for systems using power converters as actuators. The chapter also deals with a nonlinear control technique called hysteresis control, and highlights some advantages and disadvantages of this technique. It considers two applications: dc motor drive system and regulation of an ac variable. The classic linear controllers (P, PI, and PID) are presented for dc variables. The chapter presents a linear type of controller for ac variables. A more complex control technique is presented with a cascade strategy for systems dealing with control of two variables with different dynamic responses.

  • Magnetic Core Loss

    This chapter focuses on calculating the losses within a magnetic material. These losses arise from several causes. Eddy currents induced by the time rate of change of flux in the material are one source of loss. A second source of loss is magnetic hysteresis, which is associated with the non-uniquely valued relationship between flux density and field intensity. The chapter considers a variety of empirical or behavioral approaches to modeling core loss. These are based on representing observed behavior in a mathematical form using curve fitting. The chapter also considers some other approaches to the modeling of hysteresis behavior. These include Jiles-Atherton model and the Preisach model. These are time domain models that predict the specific B-H trajectory. They offer significantly more information than the empirical models.

  • Magnetic Circuits and Transformers

    This chapter contains basic concepts that can be used for all rotating machines and for power transformers. It presents a more complete analysis and more detailed circuit models of real-life transformers. When the transformer operates in sinusoidal steady state, the corresponding phasor circuit can be used to analyse it. Three-phase transformers can have different construction modes. The chapter briefly presents only the transformers created as a three- phase bank of single-phase transformers. Magnetic hysteresis is important also from an energy point of view: it can be demonstrated that hysteresis phenomenon implies loss of energy in the magnetic circuit of the transformer, which reduces efficiency and heats the iron.

  • Magnetic Properties of Materials for MRAM

It explains the basic concepts of practical magnetic tunnel junctions, including ferromagnets, antiferromagnets, magnetic anisotropy, exchange bias, interlayer exchange coupling, and synthetic antiferromagnetic structures. The chapter covers the magnetotransport properties of giant magnetoresistive multilayers as well as of magnetic tunnel junctions with either an amorphous aluminum oxide or a crystalline magnesium oxide tunnel barrier_.

  • Rotor and Stator Laminated Cores

    This chapter discusses rotor and stator cores and, in particular, steel lamination and insulation on these laminations, as well as how the laminations are fabricated into cores. It restricts the materials, processes, and insulation of laminated stator and rotor cores, that is, electromagnet application. Magnetic fields are characterized by the magnetic flux, the magnetic flux density or B, and the magnetic field intensity or H. The latter is called the magnetomotive force or mmf when the field is generated by an electromagnet. Laser cutting is also used for limited new production and prototypes, for modifications of laminations from existing dies or punched stock, and to replace damaged laminations during core repairs. The annealing is carried out in an inert atmosphere to prevent oxidation of the metal surface. Burr removal is often done by a grinding or sanding operation that also leaves some bare metal where the burrwas removed.
