  • 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.

  • 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.

  • 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.

  • 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.

  • Inductive Coupling

    Radio frequency identification (RFID) takes advantage of inductive links to not only power up the ultralow-power RFID tags, which cannot have batteries due to their size, weight, and lifetime limitations, but also read the tags, stored information through back telemetry. The main physical principle behind the operation of telemetry coils is Faraday's law, which states that when the total magnetic flux through a conductive loop. Power amplifiers are commonly utilized in wireless power transmission links to drive the primary coil by converting the DC power of an external source. Bidirectional wireless data transmission is essential for IMD and RFID systems to establish a short-range wireless communication between the Tx and Rx parts of the system. Inductive coupling as a viable technique to power up devices and also establish a wireless data communication link is widely used to remove direct electrical contact between the energy source and the target device.

  • 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.
