  • Magnetic Force

    The magnetic vector potential and the magnetic flux density computed by the finite-element method can be used to find magnetic forces of magnetic actuators and sensors. This chapter discusses magnetic flux plots, magnetic energy, magnetic pressure, permanent magnets, and magnetic torque, which are all related to magnetic force; these all are also examples of postprocessing of finite-element solutions. For both 2D and 3D finite-element models, it is vital that flux line plots and/or flux density plots be obtained and examined. The chapter demonstrates a method, other than the method of virtual work, for the computation of Lorentz force. It also demonstrates the calculation of magnetic volume forces on permeable particles.

  • Other Magnetic Performance Parameters

    This chapter discusses a few magnetic performance parameters. After defining these key parameters, they are evaluated using reluctance and finite-element methods. Their relations with energy and force are also explained. The parameters discussed in the chapter are magnetic flux, flux linkage, inductance, capacitance and impedance.

  • DQ Coils for Large Tolerance EV Chargers

    In addition to the asymmetric coil structure in the previous chapter, another idea of increasing tolerance is to use DQ power supply coil sets for wireless stationary electric vehicle (EV) chargers. Two coil sets having a 90 phase difference can increase tolerances for longitudinal, lateral, as well as diagonal displacements. Each power supply coil set consists of two same magnetic poles to generate uniform magnetic flux density over the power supply coil. A prototype inductive power transfer system (IPTS) using the proposed DQ power supply coil sets for the wireless stationary EV chargers was fabricated for the experimental verifications with an operating frequency of 85 kHz to satisfy Standard J2954 of the Society of Automotive Engineers (SAE). From simulation and experiment results, it is found that the lateral, longitudinal, and diagonal displacements of the proposed coil sets increase by about 35% and 19%, respectively, at an airgap of 150 mm, compared with conventional rectangular loop???type coils.This chapter is based on the paper by S,Y. Jeong et al., ???DQ???quadrature coil sets with large tolerance for wireless stationary EV chargers,??? in IEEE 2015 WoW, June 2015.

  • 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.

  • Magnetohydrodynamics Formulation

    Magnetohydrodynamics (MHD) was originally applied mostly to astrophysics and geophysics. In MHD the motion of collective charged particles is described by an electrically conducting fluid with the usual fluid dynamic variables of velocity, density and pressure or temperature. The interactions of fluid dynamics and electromagnetics are exclusively derived from the magnetic flux density. This chapter presents a systematic derivation of the governing equations of MHD. The first and foremost assumption for MHD formulation is that the physical phenomena are describable by macroscopic scales or in the framework of continuum mechanics. The electromagnetic waves are compound waves for which the compression and rarefaction components can coexist and the direct consequence of the nonconvexity of the ideal MHD equations. The chapter discusses additional computational simulations to show the lack of detailed plasma composition that is required for determining electric conductivity of plasma in the MHD formulation.

  • Effect of High Fault Currents on Protection and Metering

    This chapter reviews the literature on effects of high fault currents on protection and metering equipment. It discusses the capabilities and limitations of existing short-circuit protection devices. High fault currents are well known to cause saturation of iron core current transformers (CTs). This can adversely affect the performance of system protection devices. CTs are intended to deliver a secondary current that is directly proportional to the primary current with as little distortion as possible. During normal operation, the CT secondary winding induces a magnetic flux that opposes and nearly cancels the primary induced flux. CT saturation may cause overcurrent relays to misoperate or fail to operate, resulting in a failure of the protection system. Protective relaying is an integral part of any electrical power system. The fundamental objective of system protection is to quickly isolate a problem so that the unaffected portions of a system can continue to function.

  • Narrow???Width Single???Phase Power Rail (I???type)

    In this chapter, an advanced version of on???line electric vehicles (OLEVs) is introduced as an introductory example of road???powered electric vehicles (RPEVs). Because the author is heavily involved in the development of OLEVs, this chapter will guide readers to how practical problems are dealt with. This chapter is based on the paper by J. Huh, S.W. Lee, W.Y. Lee, G.H. Cho, and C.T. Rim, ???Narrow???width inductive power transfer system for on???line electrical vehicles,??? IEEE Trans. on Power Electronics, vol. 26, no. 12, pp. 3666???3679, December 2011.The inductive power transfer system (IPTS) with a narrow rail width, a small pick???up size, and a large airgap is explained, as an extension of previous research on OLEVs, in this chapter. By introducing a new core structure, the orientation of the magnetic flux alternates along with the road; hence, an inductive power transfer system with a narrow rail width of 10 cm, a large airgap of 20 cm, and a large lateral displacement of about 24 cm was implemented. The resonant circuit of the inductive power transfer system, driven by a current source, was fully characterized. The experimental results showed that the maximum output power was 35 kW and that the maximum efficiency was 74% at 27 kW.
