Optimization of wireless power transmission for two port and three port inductive link
IOP Conference Series: Materials Science and Engineering, 2013
Recent developments have shown that the use of buried electronic devices or body implants has been becoming prevalent. Such low power devices are being powered up through non-contact means utilizing inductive coupling from external powering source. Inductive coupling not only solves the issue of energy availability but helps collecting the sensed data that can be archived or used for subsequent monitoring purposes. This paper analyses the performance of two-port and three-port inductive links in terms of power sent, power received and power transfer efficiency. All the above mentioned parameters have been plotted using analytical approach and obtaining simulation where required. The effect of mutual coupling has been studied in detail for both systems and demonstrated by plotting the power transfer efficiency for different values of the coefficient of coupling (k) using MATLAB. Results show that power transfer efficiency depends highly upon the value of k.
Recent technological advancements in sensors and conditioning electronics are finding applications in many areas including non-contact monitoring in remote areas, in the medical field and better automation in the automotive industry. Such electronics need power sources both through wired and wireless means. Given this, inductive coupling is the most appropriate and potent approach to carry out this job adequately. The benefit of inductive coupling is that, it can be utilized for both telemetry and powering purposes that is to collect the sensed data from the device. This paper explores the power transfer efficiency performance of an inductive coupling system. Design parameters have been simulated for the variation on the load resistor, the tuning of the inductive circuit and the impact on coil orientation has been studied.

PULSE DURATION MODULATION BASED INDUCTIVE (PDM) LINKS FOR WIRELESS POWER TRANSFER SYSTEM
International Journal of Scientific & Engineering Research, Volume 7, Issue 9, September-2016 874 ISSN 2229-5518, 2016
Wireless power transfer system (WPT) is a technology that transports electric energy to another location without physical wires. It is a good idea to wirelessly transmit electricity especially where it is inconvenient, impractical, hazardous, or impossible to reach, but the method at which the electric power is being transmitted is most important factor of wireless power transmission. Energy should be transmitted with power losses and interference with other electronic devices which required a Pulse duration modulation. Pulse duration modulation (PDM) based inductive links for wireless power transfer system is a novel innovation in wireless power transmission. Several techniques and technologies has been used in the past for wireless power transfer but none of the techniques uses PDM or pulse width modulation (PWM) which offer a fast switching that can easily be controlled or manipulated via feedback networks. The longer the switch rate of PDM compared to the off periods can determine the efficiency and total power supplied to an inductive link. PDM as one of the principal algorithms used in power inverters and photovoltaic system for maximum power point tracking and here it offers the best technique for adequate power output at the receiver end of wireless power transmission system. Since efficiency plays an important role in the design of wireless power transfer so the introduction of PDM makes a significant contribution to knowledge for eliminating power loss in WPT switching techniques.--Introduction:
Wireless Power Transmission for Embedded Systems
Now a days in our daily life every where we are using embedded systems. For this embedded systems we have to provide the power supply to work. That power supply we are providing by using wires. Due to this complexity and cost of the embedded systems is increasing in order to reducing this we are going for wireless power transmission to the embedded systems. This paper gives an effective, high performance technique which can efficiently transmit the power to our embedded systems without using wires. It can give an efficiency of about 95% with non radiative energy. This way of transmission does not affect the environment surroundings. This technique includes resonating inductive coupling in sustainable moderate range and transfer of power through microwaves using rectennas. With this we can avoid the confusion and danger of having long, hazardous and tangled wiring.
Wireless Power Transmission with Short and Long Range Using Inductive Coil
Wireless Engineering and Technology
In today's time each individual needs remote framework, yet at the same time control transmission for low power gadgets are wired in nature. Consistent power supply is one of the real issues in the motivation behind the utilization of remote sensor network. Yet, in the power arrangement of remote Sensor Network, the battery has an extremely constrained lifetime and is not supplanted yet by some other persistent power framework. There are separate techniques proposed for shorter and more separate power transmission: Inductive coupling, resonant inductive coupling and air ionization for short separations; microwave and Laser transmission for longer separations. The pioneer of the field, Tesla endeavoured to make a capable, remote electric transmitter more than a century back that has now observed an exponential development. This paper overall lights up all the effective strategies proposed for transmitting power without wires. This study is important for find out the future ways of power transmission. These methods are so important in today's world because of drastic wastage of power. Common wireless power transmission is a point-to-point control transmission. It was demonstrated that the power transmission effectiveness could approach near 100%.
