  • 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.

  • 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

    _This chapter reviews the main materials used in magnetic random¿¿¿access memory and their properties. 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_.

  • 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.

  • Magnetic Actuators Operated by AC

    Since alternating current (AC) voltage is commonly available, many magnetic actuators are designed for AC operation. In most cases, the direct current (DC) actuators must be substantially modified for AC operation. This chapter discusses the issues that are needed to be considered for AC-operated magnetic actuators. Separate sections are devoted to the concepts of skin depth, power losses in laminated steel, equivalent circuit and solid steel, force pulsations, and cuts in steel.

  • Calculation of Induction Machine Losses

    The computation of losses is the most difficult and challenging aspect of machine design. The power losses in an induction motor can be relegated to five elements. Stator conductor loss, rotor conductor loss, iron loss, stray‐load loss, friction and windage loss. The increase of rotor resistance has a beneficial effect in aiding starting capability of squirrel‐cage induction machines and nearly all conventional machine designs enhance motor starting capability by specially selected rotor bar shapes. The calculation of iron losses associated with the rotor teeth are again found by adding up the losses in each rotor tooth, properly weighting the terms by the sine of the location of the tooth with respect to a pole pitch. The windage losses are produced by rotation and depend upon the peripheral speed of the rotor, the rotor diameter, the core length and generally upon the construction of the machine.

  • 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.

  • HBFEM and Its Future Applications

    By using the harmonic balance-finite element method (HBFEM) approach, magnetic nonlinear characteristics, hysteresis losses, eddy current losses, and magnetic flux distribution for each harmonic component can be calculated and presented. HBFEM can provide magnetic flux distribution and eddy current losses at each harmonic. The calculation method of the electromagnetic coupling is implemented by combining the electric circuit, which reflects characteristics of the ports, with the magnetic circuit and the internal magnetic field's distribution. Considering the periodic characteristics of electromagnetic fields under steady-state excitation, a limited Fourier series is used to represent the periodic behavior of the steady-state variables, and solving equations in the time domain can be avoided. The harmonic balance method is the effective method for obtaining the approximate periodic solution of a nonlinear differential equation. The magnetic circuit model established from the geometric structure of the power transformer can be used to calculate and analyze non-linear electromagnetic problems, considering the coupled electric circuits.
