  • 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.

  • Distributed Windings and Rotating Electric Machinery

    This chapter focuses on a complicated winding arrangement known as a distributed winding, which is often used in rotating electric machinery. In these machines, the goal is to establish a continuously rotating set of north and south poles on the stator, which interact with an equal number of north and south poles on the rotor, to produce uniform torque. The winding function has three important uses. First, it is useful in determining the MMF caused by distributed windings. Second, it is used to determine how much flux links a winding. Third, the winding function is instrumental in calculating winding inductances. The chapter talks about the air-gap magnetomotive force (MMF). It explains the calculation of inductances of distributed windings. The problem of the computation of leakage inductance of a stator winding and the problem of finding the resistance of a distributed winding are considered.

  • Magnetics and Magnetic Equivalent Circuits

    This chapter sets forth the background needed to analyze electromagnetic and electromechanical systems. It includes a review of magnetics, particularly magnetostatics. The notion of magnetic equivalent circuits is explored as a fairly accurate technique for the analysis of magnetic systems. The chapter talks about (a) Ampere's law, and the relationship between magnetomotive force (MMF) sources and MMF drops in the form of Kirchhoff's MMF law, (b) the relationship between fluxes going into a common volume or node that is governed by Kirchhoff's flux law, and (c) Ohm's law for magnetic equivalent circuits. A section describes the relationship between the magnetic equivalent circuit and the corresponding electric equivalent circuit, and highlights the concepts of flux linkage and inductance. It explains leakage permeance so as to create a more accurate magnetic model, and the flux path. The final section of the chapter discusses finite element analysis (FEA), another technique for magnetic analysis.
