High-frequency alternators

S. E. Rauch; L. J. Johnson Electrical Engineering, 1954

High shaft speeds, which permit direct coupling of alternators to high-speed turbines, have made the largest contribution to the increased power ratings of alternators. Consequently, high-frequency alternators are becoming widely used in air-borne equipment. These alternators should find many other applications as in computer and telemetering systems, welding applications, and arc lighting.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • Magnetic Actuator Transient Operation

    This chapter discusses the transient effects of turning on (or off) the direct current (DC) and alternating current (AC) currents or voltages. The basic timeline for transient operation of magnetic actuators consists of many steps. For many applications, a time delay slows the speed of response. The steps discussed in the chapter are: (i) the magnetic flux density rises, partly determined by a time constant called the magnetic diffusion time or nonlinear infusion time; (ii) the force rises as the magnetic flux density rises; (iii) the force produces acceleration of the armature and/or attached mass; and (iv) after a certain time, during which the armature may or may not reach the end of its stroke, the energizing circuit may be turned off; if the current suddenly becomes zero, then the magnetic flux density (and related force) falls, partly determined by the magnetic diffusion time or nonlinear effusion time.

  • 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.

  • 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.
