Abstract:
Abstract. Inductive and capacitive end couplings in the design of combline microwave filters are compared. For instance, a combline microwave cavity filter for the E1 Galileo band (1559–1591 MHz, 2 % fractional bandwidth) is considered. The inductive end coupling is composed of an L-shaped pin in galvanic contact with the end resonator, while the capacitive end coupling is realized by a straight pin parallel to the end resonator's axis. Although both end couplings can realize the desired external quality factor, the capacitive end coupling is easier to manufacture, while the inductive end coupling is less sensitive to the design parameter. An excellent agreement between synthesized (5th-order Chebyshev mask with 0.05 dB ripple) and measured responses is observed for the realized prototype of the filter. The insertion losses at the center frequency are 1.72 and 1.53 dB for the inductive and capacitive end couplings, respectively. The spurious-free ranges are up to 8.23 and 8.92 GHz for inductive and capacitive end couplings, respectively.

Abstract:
Wireless power transmission (WPT) is the efficient transfer of electrical energy from one point to wirelessly. This can be used for applications where instantaneous or continuous power delivery is required. The objective of this paper is to design and build a wireless electrical power transmission through space and charging of low-power devices. This system will work by using resonant coils to transfer power from an AC line to a resistive load. The Power can be transmitted using short-range inductive coupling, medium-range resonant induction, and high-range electromagnetic wave power transmission. The objective also includes the possibility of charging multiple low-power devices simultaneously using a single source using a single electrical outlet. Keywords: Wireless Power Transfer, Inductive Coupling Wireless, Energy Systems Design, Resonant Inductive Coupling.

Abstract:
Considering the massive development that took place in the past two decades, wireless power transfer has yet to show the applicability to be used due to several factors. This work focuses on determining the main parameters like, mutual inductance, and coupling coefficient for a pair of helical coils for wireless power transfer applications. These parameters are important in designing and analyzing a wireless power transfer system based on the phenomenon of inductive/ resonant inductive coupling. Here presents a simple approach based on fundamental laws of physics for determining the coupled coil parameters for single layered helical coils. The results conducted by computer simulation which is MATLAB. Furthermore, this analysis is used to study the effect of change in coil diameter, mutual inductance coefficient and change in distance between coils on parameters like self and mutual inductance of coupled coils which is of great importance in Wireless Power Transfer applications. The research yielded promising results to show that wireless power transfer has huge possibility to solve many existing industrial problems.

Abstract:
Increasing the demand for developing implantable devices and sensors promotes the concept of the wireless power transfer. The implanted glucose sensors, for example, shall be built small enough to allow implanting it inside the patients' body [1] to indicate the readings easily. It grants the patients the ability to read data simply through a receiver located out of the body. However, there is a problem in most of these sensors in providing them with the necessary power by using traditional chargers because any direct contact with these devices is impossible. Therefore, scientists and researchers investigate new solutions and methods to maintain transferring enough power to charge the battery of the sensor. Among all of these methods, the inductive coupling proves its ability in transmitting the power wirelessly to the application with high efficiency. This paper presents a wireless charging system to transfer the power from an external charger to an implanted device based on the inductive coupling. It discusses different considerations and possibilities in designing and implementing the proposed charger to provide enough power to the largest possible distance.

Abstract:
This research described the construction and implementation of the contactless wireless mobile phone battery charging which becomes popularity nowadays. The power was transferred to the destination by means of inductive coupling between two coils. In transmitter part, the desired frequency was produced from Arduino by means of PWM Pulse Width Modulation . This frequency was used to drive the induction coil by using MOSFET driver. The MOSFET operated as a switch in terms of T on and T off. The power in transmitter coil was transmitted to surroundings by means of electromagnetic field. The receiver coil was induced by electromagnetic field and produces DC voltage. That converted DC voltage was filtered by capacitor and then regulates to required voltage by using voltage regulator. Optimal frequency range for maximum power transfer is gained by performing theatrical approach and experimental test.

Abstract:
In order to utilize the energy from the renewable energy sources, power conversion system is necessary, in which the voltage source inverter (VSI) is usually the last stage for injecting power to the grid. It is an economical solution to add the function of power quality conditioning to the grid-connected VSI in the low-voltage distribution system. Two multifunctional VSIs are studied in this paper, that is, inductive-coupling VSI and capacitive-coupling VSI, which are named after the fundamental frequency impedance of their coupling branch. The operation voltages of the two VSIs are compared when they are used for renewable energy integration and power quality conditioning simultaneously. The operation voltage of the capacitive-coupling VSI can be set much lower than that of the inductive-coupling VSI when reactive power is for compensating inductive loads. Since a large portion of the loads in the distribution system are inductive, the capacitive-coupling VSI is further studied. The design and control method of the multifunctional capacitive-coupling VSI are proposed in this paper. Simulation and experimental results are provided to show its validity.

Abstract:
Wireless power transfer through inductive coupling is proposed in this paper. Based on the concept of Tesla, the circuit was designed using two parallel inductors that are mutually coupled. The designed was split into two which are transmitter part and receiver part. The circuit was simulated using proteus simulation software. The results had shown that the changes in a number of turn of the inductor coils and distance of the two resonators affecting the efficiency of the power transfer. The wireless power transfer can be described as the transmission of electrical energy from the power source to the electrical load without any current-carrying wire connecting them. Wireless power transfer is deemed to be very useful in some circumstances where connecting wires are inconvenient. Wireless power transfer problems are different from wireless telecommunications such as radio. Commonly, wireless power transfers are conducted using an inductive coupling and followed by magnetic induction characteristics. In this project, we use magnetic induction using copper wire with a different diameter. By using these different diameters of wires, we are going to see the power transfer performance of each wire. It is possible to achieve wireless power transfer up to 30 centimeters between the transmitter and the receiver with a higher number of coil's turn. As concern as it may seem, the wireless power transfer field would be in high demand for electric power to be supplied in the future.

Abstract The inductively coupled transmission chain can carry multiple Marine sensors, which is an important means to obtain Marine data, but the current transmission rate of inductively coupled data is low, which can not meet the needs of future Marine data transmission. The induction coupling system designed in this paper adopts the structure of double magnetic loop and a double-winding, and adopts the new single frequency different code algorithm to realize the data transmission rate of 150kbps. Different water environments were set up in the laboratory for testing, and the lower bit error rate was found in the water environment with the ion concentration of 10%-35%, which met the requirements of inductive coupling data transmission in a multi-water environment. It is of great significance to establish the research of underwater inductively coupled long-distance transmission for the subsequent design of a new inductively coupled transmission chain and the improvement of the data transmission rate.

Abstract:
Wireless power transmission (WPT) is the method that transferring electrical energy from power source to electrical without any physical contact and it can be used to transfer power to electricity dependent systems or devices. In WPT, electromagnetic energy is produced to transmit the energy from power source (transmitter) to the load (receiver) via resonant inductive coupling. This article focuses on the design of a resonant inductive coupling using parallel-T topology in coupling WTR and combined of single transmitter with multiple receivers. In addition, principle of magnetic wave between the transmitter and receiver with related parameters is utilized to develop in WPT. A parallel-T topology that consists of T-matching network for secondary side is proposed as it is more suitable for weak coupling wireless power transfer applications. Besides that, three circuits are designed to show the resonant inductive coupling for WTP which including the circuit with and without matching network and the circuit of single transmitter with multiple receivers. The simulation of output voltage and output current are observed to relate the effects of frequency on the circuit. The graph of output voltage and power are plotted to show the pattern on effect of the frequencies to the resonant inductive coupling circuit.

Abstract:
Electromagnetic coupling is the mechanism by which one circuit induces noise or interference in another adjacent circuit. This coupling mechanism generates Electromagnetic Interferences that degrade or even interrupt the operation of adjacent circuits. However, it is often rare in the academic and professional fields of power electronics to have sufficient knowledge to identify and address this problem. Therefore, intuition plays an important role in anticipating and dealing with this problem. This article describes the basic principles of this coupling mechanism and proposes simple solutions to this electromagnetic interference problem. These solutions must be applied right from the design phase of any electronic equipment. The problem described and its solutions are experimentally validated in a simple test circuit. This article is mainly oriented to the academic and professional field of power electronics and aims to describe in a simple and experimental way the problems associated with inductive coupling.

Abstract:
The main contribution of this paper is the inductive compensation of a wireless inductive power transmission circuit (IPT) with resonant open-loop inductive coupling. The variations in the coupling coefficient k due to the misalignment of the transmitter and receiver are compensated with only one auxiliary inductance in the primary of the inductive coupling. A low-power prototype was implemented with the following specifications: input voltage Vin = 27.5 V, output power Po = 10 W, switching frequency f = 500 kHz, output voltage Vo = 12 V, transmission distance d = 1.5 mm. Experimental results varying the distance “d” with several values of the compensation inductor demonstrate the feasibility of the proposal. An efficiency of 75.10% under nominal conditions was achieved. This proposal is a simple compensation topology for wireless chargers of cellular phones presenting small distances between the transmitter and receiver.

The inductive wireless power transfer efficiency is determined by the coupling factor and coil quality factors. This paper studies the coupling factor of an inductive power link (IPL) for wireless power transfer in advanced brain-machine interface applications. By comparison to the experimental results, the various design tools including Maxwell simulation and two analytical models are evaluated for prediction of the coupling factor. The coupling factors of IPLs with different design parameters are also analyzed. The results show that for specific wireless power transfer distances, the coupling factor of an IPL is mainly related to the size and fill ratio of the coils, while is almost independent of the coil track pitch, coil width/pitch ratio, and track thickness.

Full text
Abstract:
This paper analyzes the output voltage of an inductive wireless power transfer (WPT) depending on coupling conditions. When the optimum efficiency and maximum output power are obtained, it is called critical coupling, so the receiving coil and the transmitting coil should be separated by a certain distance. When the distance between the transmitting coil and receiving coil is very short, it is called over coupling, and output power decreases with the optimal operating state of the critical coupling condition. To design the entire circuit system for the inductive WPT depending on the coupling condition, it is beneficial to analyze the output voltage according to a load variation, an input voltage, and an operating frequency. Therefore, the output voltage depending on the coupling condition in the inductive WPT is analyzed in this paper. The output voltage gain in critical coupling condition is greater than one and is not affected by a load variation by a series LC resonant operation. The reduced output power in an over coupling condition can be recovered by a series LLC resonant operation. In addition, the output voltage gain is almost one and is affected by the load variation in the over coupling condition. A 5W prototype is implemented with the wireless power consortium standard coils and experimental results are shown to verify theoretical analysis and operation.

Abstract:
Transmitter component of high power inductive wireless transmission systems for electric busses and trucks should be embedded in the road to ensure a free circulation of vehicles and to ensure a good mechanical resistance of the pavement, in the charging region, similar to the rest of the road. In such application, ferrites cannot be envisaged as magnetic flux concentrators due to their fragility. An adequate solution to replace the ferrites consists in using magnetic concrete as magnetic field concentrator for wireless inductive transmission system. This solution is analyzed in this paper and used for an MIMO (Multiple-Input-Multiple-Output) inductive wireless power system based on Double-D structure coils, for a transferred power of 125 kW, corresponding to the standard project SAE J2954-2, sufficient for an electric bus for 50 persons.

Abstract:
<p>This paper presents investigations on capacitor compensation topologies with different inductive coupling links for loosely coupled inductive power transfer (IPT) system. In general, the main constraint of the loosely coupled IPT system is power losses due to the large leakage inductances. Therefore, to overcome the aforementioned problem, in this work, capacitor compensation is proposed to be used by adding an external capacitor to the system. By using this approach, the resonant inductive coupling can be achieved efficiently and hence the efficiency of the system is also increased significantly. This paper analyzes the performance of two different compensation topologies, which are primary series-secondary series (SS) and primary series- secondary parallel (SP) topology. The performance of such topologies is evaluated through the experimental results at 1MHz operating frequency for different types of inductive coupling. From the results, SS topology produces a high power transfer but SP topology gives better efficiency.</p>

We investigate the galvanic coupling schemes of superconducting flux qubits. From the fundamental boundary conditions, we obtain the effective potential of the coupled system of two or three flux qubits to provide the exact Lagrangian of the system. While usually the two-qubit gate has been investigated approximately, in this study we derive the exact inductive coupling strength between two flux qubits coupled directly and coupled through a connecting central loop. We observe that the inductive coupling strength needs to be included exactly to satisfy the criteria of fault-tolerant quantum computing.

This paper presents and applies an inductive directional coupling technology based on spread spectrum time domain reflectometry (SSTDR) for non-intrusive power cable fault diagnosis. Different from existing capacitive coupling approaches with large signal attenuation, an inductive coupling approach with a capacitive trapper is proposed to restrict the detection signal from transmitting to power source and to eliminate the effect of the power source impedance mismatch. The development, analysis, and implementation of the proposed approach are discussed in detail. A series of simulations and experiments on cables with different fault modes are conducted, along with comparison of existing capacitive coupling, to verify and demonstrate the effectiveness of the proposed method.

Abstract:
Wireless power transfer through inductive coupling is proposed in this paper. Based on the concept of Tesla, the circuit was designed using two parallel inductors that are mutually coupled. The designed was split into two which are transmitter part and receiver part. The circuit was simulated using proteus simulation software. The results had shown that the changes in a number of turn of the inductor coils and distance of the two resonators affecting the efficiency of the power transfer. The wireless power transfer can be described as the transmission of electrical energy from the power source to the electrical load without any current-carrying wire connecting them. Wireless power transfer is deemed to be very useful in some circumstances where connecting wires are inconvenient. Wireless power transfer problems are different from wireless telecommunications such as radio. Commonly, wireless power transfers are conducted using an inductive coupling and followed by magnetic induction characteristics. In this project, we use magnetic induction using copper wire with a different diameter. By using these different diameters of wires, we are going to see the power transfer performance of each wire. It is possible to achieve wireless power transfer up to 30 centimeters between the transmitter and the receiver with a higher number of coil's turn. As concern as it may seem, the wireless power transfer field would be in high demand for electric power to be supplied in the future.

Abstract:
Abstract Inductive coupling temperature-salinity-depth chain is an important instrument for measuring the deep-sea environment. Using the electromagnetic induction principle, the bidirectional data transmission from the overwater control equipment to an underwater sensor can be realized. However, due to attenuation in marine environments, it is difficult to realize a long distance and efficient transmission. In order to accurately analyze the channel transmission characteristics of an inductive coupling temperature-salinity-depth chain, a three-level distributed prototype of the transmission channel using COMSOL Multiphysics is constructed. The transmission characteristics of the channel are analyzed at various depths. The analysis of a three-level simulation model demonstrates that the seawater resistivity is relatively stable, independent of detection depth. When the transmission frequency is 10 kHz and the length of the cable is 60 m, the transmission efficiency of the single node transmission channel is 2.9%. Moreover, the transmission efficiency is reduced to 2.6%, when the sensor nodes in the transmission channel are 10, while it may be less than 1% with the decrease of the inductance. The seawater resistivity and the inductance of magnetic ring significantly influence the performance of transmission channel. Optimizing the inductance of the magnetic ring and improving the frequency of the transmission signal are extremely important for the improvement of the transmission performance of an electromagnetic inductive coupling temperature-salinity-depth chain.

Abstract:
The phase voltage of the tripping phase contains capacitive coupling voltage and inductive coupling voltage. According to the continuous improvement of the national voltage grade, the parallel transmission lines on the same tower are widely used in main transmission section. The protection will trip the fault phases while inner-line or inter-line faults occur. The phase voltage of the tripping phase contains capacitive coupling voltage and inductive coupling voltage. Terminal voltage when the lines are in transient faults is much higher than in permanent faults because of the line discharging by fault point. Simulation studies show that the terminal voltage criterion can distinguish transient and permanent fault in parallel transmission lines.

Due to the development of biomedical microsystems technologies, the use of wireless power transfer systems in biomedical application has become very largely used for powering the implanted devices. The wireless power transfer by inductive resonance coupling link, is a technic for powering implantable medical devices<strong> </strong>(IMDs) between the external and implanted circuits. In this paper we describe the design of an inductive resonance coupling link using for powering small bio-implanted devices such as implantable bio-microsystem, peacemaker and cochlear implants. We present the reduced design and an optimization of small size obtained spiral coils of a 9.5 mm<sup>2</sup> implantable device with an operating frequency of 13.56 MHz according to the industrial scientific-medical (ISM). The model of the inductive coupling link based on spiral square coils design is developed using the theoretical analysis and optimization geometry of an inductive link. For a mutual distance between the two coils at 10mm, the power transfer efficiency is about 79% with , coupling coefficient of 0.075 and a mutual inductance value of 2µH. In comparison with previous works, the results obtained in this work showed better performance such as the weak inter coils distance, the hight efficiency power transfer and geometry.

Abstract:
In two-level approximation, we investigate the influence of mutual inductive coupling in superconducting quantum circuits on the decoherence of flux qubits under sub-Ohmic thermal bath environment by utilizing Bloch-Redfield function. The investigation results show: (1) The memory effect existing in the solid-state environment is beneficial to prolong the decoherence time of the superconducting flux qubit, building sub-Ohmic thermal bath environments can improve the decoherence of the solid-state qubit. (2) When the quantum system and the thermal bath are in weak coupling, generally speaking, the mutual coupling effect between circuit elements will destroy the quantum coherence; but when the quantum system and the thermal bath are in strong coupling, it will help to enhance the decoherence time by controlling the mutual inductive coupling between the loop components.

Abstract:
This paper deals with the design and fabrication of durable radio frequency identification (RFID) passive tag with inductive coupling, operating at ultra-high frequencies, dedicated to the identification and monitoring of professional textile products. A reliable architecture for the tag transponder is proposed, featuring a minimal number of galvanic contacts: The two pins of the integrated circuit are connected to the terminals of the inductive coupling loop by using surface mount technology welding. The transponder is encapsulated with an electrically insulating material which is waterproof and resistant to mechanical, thermal, and chemical stress. The antenna is inductively coupled to the transponder through a double loop which substantially reduces the length of the tag and significantly improves the coupling factor, enabling the tag to operate at a low power level. The reliability and flexibility of the tag is obtained by using appropriate materials and manufacturing methods for the ultra-high frequency (UHF) antenna by embroidering a multifilament stainless steel wire on textile support. The washing cycle tests have validated the applicability of this flexible and washable RFID tag, and its electromagnetic performance was experimentally assessed in an independent laboratory.

Abstract:
Inductive Wireless Power Transfer (IWPT) is the most popular and common technology for the resonance coupling power transfer. However, in 2007 it has experimentally demonstrated by a research group from Massachusets Institute of Technology (MIT) that WPT can be improved by using Magnetic Resonance Coupling Wireless Power Transfer (MRC WPT) in terms of the coupling distance and efficiency. Furthermore, by exploiting the unused, high-frequency mm-wave band which are ranging from 3~300 GHz frequency band, the next 5G generations of wireless networks will be able to support a higher number of devices with the increasing data rate, higher energy efficiency and also compatible with the previous technology. In this work, a square planar inductor with the dimension of 6.1 x 6.1 mm is designed, and the resonators have the same self-resonance frequency at 14 GHz. The coil resonators have been laid on Silicon and Oxide substrate to reduce the loss in the design. From the CST software simulation and the analytical model in MATLAB software, it has been shown that the MRC WPT design has improved the performance of IWPT design by 40% power transfer efficiency. MRC WPT design also has larger H-Field value which is 705.5 A/m, as compared to the IWPT design which has only 285.6 A/m when both Transmitter(Tx) and Reciever(RX) is at 0.3 mm coupling distance.

Abstract:
Considering the massive development that took place in the past two decades, wireless power transfer has yet to show the applicability to be used due to several factors. This work focuses on determining the main parameters like, mutual inductance, and coupling coefficient for a pair of helical coils for wireless power transfer applications. These parameters are important in designing and analyzing a wireless power transfer system based on the phenomenon of inductive/ resonant inductive coupling. Here presents a simple approach based on fundamental laws of physics for determining the coupled coil parameters for single layered helical coils. The results conducted by computer simulation which is MATLAB. Furthermore, this analysis is used to study the effect of change in coil diameter, mutual inductance coefficient and change in distance between coils on parameters like self and mutual inductance of coupled coils which is of great importance in Wireless Power Transfer applications. The research yielded promising results to show that wireless power transfer has huge possibility to solve many existing industrial problems.
