  • Theory of Electromechanical Energy Conversion

    The theory of electromechanical energy conversion allows to establish expressions for torque in terms of machine electrical variables, generally the currents, and the displacement of the mechanical system. This theory, as well as the derivation of equivalent circuit representations of magnetically coupled circuits, is established in this chapter. Although the analysis of transformers and electric machines is generally performed assuming a linear magnetic system, in the practical design of many of these devices, some saturation occurs and heating of the magnetic material exists due to hysteresis loss. The chapter talks about the method of incorporating these effects of saturation into a computer representation. Expressions for the energy stored in the coupling fields and for electromagnetic and electrostatic forces are also derived. The chapter then briefly considers a graphical interpretation of the energy conversion process, and concludes with a discussion on the steady‐state and dynamic performance of the elementary electromagnetic system.

  • 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.

  • Magnetic Mirror Model

    Improved magnetic mirror models (IM3) for mono and dual coils with a finite width and infinite permeability are explained in this chapter [47]. By introducing a mirror current, which is located at the same distance from a source current but with a smaller magnitude than the source current, the magnetic flux density of the mono and dual coils can be determined in a closed form. The ratio of the mirror current and source current is identified as a function of the width of the core plate and the distance between the source current and core plate, as rigorously derived from the finite‐element method (FEM) simulations. Applying the proposed IM3to the mono and dual coils used for wireless electric vehicles, the magnetic flux density over an open core plate is analyzed and its maximum points on the plate are found, which is crucial in the design of the coils to avoid local magnetic saturation. Furthermore, the magnetic flux density when a pick‐up core plate is positioned over a primary core plate is also analyzed by introducing successive mirror currents. The proposed magnetic mirror models are extensively verified by experiments as well as site tests, showing quite promising practical usefulness.This chapter is based on the paper by W.Y. Lee, J. Huh, S.Y. Choi, X.V. Thai, J.H. Kim, E.A. Al‐Ammar, M.A. El‐Kady, and C.T. Rim, “Finite‐width magnetic mirror models of mono and dual coils for wireless electric vehicles,”_IEEE Trans. on Power Electronics_, vol. 28, no. 3, pp. 1413–1428, March 2013.

  • Asymmetric Coils for Large Tolerance EV Chargers

    As discussed in the previous chapter, large tolerance is one of the best characteristics of a static electric vehicle (EV) charger, but only if no severe penalty for the larger tolerance is found. In this chapter, an explanation is given of asymmetric coil sets for wireless stationary EV chargers, which have a significantly larger lateral tolerance than any others in the world.The pick‐up coil set is much smaller than the power supply coil set, thereby allowing large lateral and longitudinal displacements as well as robustness to airgap displacement. EMF is reasonably reduced by arranging magnetic poles along the EV's moving direction so that alternating magnetic flux through adjacent poles cancel each other. A dominant field analysis (DoFA) useful for complex vector magnetic flux simulation is used, which was introduced in Chapter 15 and is applicable to any resonating coils of inductive power transfer systems (IPTSs). Furthermore, a hysteresis loss model is suggested, which appropriately reflects the partial core saturation in a system analysis.A prototype IPTS including the proposed coil sets were designed and successfully verified by experiments. In the quick charging mode, maximum output power of 15 kW, large lateral displacement of 40 cm, longitudinal displacement of 20 cm, and an airgap of 15 cm were achieved, and low EMF of 6.1 μT at 20 kHz was achieved in the normal charging mode of 5 kW.This chapter is written based on the paper by S.Y. Choi, B.W. Gu, J. Huh, W.Y. Lee, J.G. Cho, and C.T. Rim, “Asymmetric coil sets for wireless stationary EV chargers with large lateral tolerance by dominant field analysis,”_IEEE Trans. on Power Electronics_, vol. 29, no. 12, pp. 6406–6420, December 2014.

  • Two‐Dimensional Omnidirectional IPT for Robots

    The IPTS for mobile robots, which has a single wire layer of easily fabricable power floor structure and an evenly displaced multi pick‐up structure for receiving uniform power, is explained. Due to its simple structure, a wide area power floor of 3.15 m_2_(1.5 m×2.1 m) could be fabricated as a prototype. Three pick‐ups with an evenly displaced angle and space are adopted where the limited bottom area of the free‐moving mobile robot is considered. The size and position of each pick‐up are appropriately selected for the given subwinding size of the power floor and magnetic pole arrangement. Experiments for the prototype show that the proposed multiple pick‐up structure lowers the spatial output power variation and that enough output power of 10 W can be obtained for the mobile robots.This chapter is based on the paper by C. Park, S. Lee, G.‐H. Cho, S.‐Y. Choi, and C.T. Rim, “Two‐dimensional inductive power transfer system for mobile robots using evenly displaced multiple pick‐ups,”_IEEE Trans. on Industry Applications_, vol. 50, no. 1, pp. 558–565, January–February 2014.

  • Foreign Object Detection

    Due to strong and high‐frequency magnetic field between transmitting (Tx) and receiving (Rx) coils of wireless stationary electric vehicle (EV) chargers, there is the possibility of them catching fire from debris of a metal piece in the magnetic field, which is inductively heated during charging. Position detection (POD) of misalignment between Tx and Rx is also needed to deliver maximum power at the optimum position.In this chapter, the FOD and POD are explained, introducing dual‐purpose non‐overlapped coil sets for both FOD and POD, which were invented by Chun T. Rim. Not only the existence of conductive object debris on a Tx coil but also the location of them are determined by an induced voltage difference of the coil sets. By measuring the induced voltage of the coil sets, displacements between a Tx coil and an Rx coil can also be found to inform drivers of their EV alignments. Moreover, the proposed FOD and POD devices do not arise from any power losses in inductive power transfer (IPT).The proposed non‐overlapped coil sets have been demonstrated by simulations and experiments for a prototype coil set. Throughout the experiments, the induced voltage difference of a coil set shows 2.19 mV (ideally zero) without foreign objects while the induced voltage difference significantly increases by 78.2 mV, which is about 35 times that of the value without objects, when eight conductive coins are located on a Tx coil. Also it is found that POD can be achieved by measuring the variation of the induced voltages in coil sets when an Rx coil moves on a Tx coil.This chapter is based on the paper by M.R. Sonapreetha. S.Y. Jeong, S.Y. Choi, and C.T. Rim, “Dual‐purpose non‐overlapped coil sets as foreign object and vehicle location detections for wireless stationary EV Chargers,” in_IEEE 2015 WoW_, June 2015, pp. 1–7.

  • Inductance Phenomena

    Inductance as a property of electrical systems, and specifically designed in a component such as an inductor, reactor, or transformer presents hazards to people who are working on the equipment or systems. The first hazard may be coming in contact with the energized conductors. Another important hazard is induced currents in conductive materials, which may cause electrical shocks, arcing, and heating. The inductance of an open-wire line increases as the conductors are separated. Infinite separation, as in a one-wire line, would mean infinite inductance. The skin effect is not strictly a form of inductance, but a frequency effect on resistance. The skin effect changes the internal inductance of a solid conductor, because the conduction occurs along the surface, making the inductance approach that of a tube rather than a cylinder. The surge impedance will determine the ratio of voltage and current for a transient wave traveling down the line.

  • Coupled Coil Model

    The core of an inductive power transfer (IPT) system can be said to be coupled inductors. In this chapter, the coupled coils are modeled as equivalent circuits. We will start from the general distributed inductor case and then derive a lumped element circuit model. Furthermore, we will derive the transformer model and M‐model, which correspond to an explicit transformer and mutual coupled coil, respectively. These two models are related to each other and shown to be equivalent. Finally, the T‐model, which has a T‐shaped structure of three inductors, is introduced and also related to the previous two models; these three models are generally unified in this book as the model of IPT.

  • 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.

  • Magnetic Field Focusing

    Contrary to the well‐known dispersing magnetic field distribution characteristic, it is possible to some extend to focus on the magnetic field by synthesizing the magnetic field generated from multiple coils. A novel synthesized magnetic field focusing (SMF) technology is explained in this chapter and a non‐radiative but focused magnetic field is experimentally demonstrated as a one‐dimensional example. Contrary to common belief, a magnetic field can be focused arbitrarily by increasing the number of current‐controlled transmitting coils in a manner similar to that of conventional beam‐forming. However, the proposed SMF is independent of the frequency when it ranges from the DC to the RF frequency. Chronic problems associated with conventional wireless power transfer and magnetic induction tomography technologies, that is, poor resolution and electromagnetic interference due to the extent of the magnetic field, can be resolved when using the proposed SMF technology. The spatial resolution of the magnetic field of an experimental kit composed of ten coils spaced 5 cm apart with a 90 cm‐long ferrite core was 12.5 cm at a distance of 10 cm, which is four times that of a non‐focusing coil and which may increase if more coils are used.This chapter is based on the paper by B.H. Choi, J.P. Cheon, J.H. Kim, and C.T. Rim, “A novel synthesized magnetic field focusing (SMF) technology,”_IEEE Trans. on Magnetics Letters_, accepted.
