Background of the Invention
The common way of transferring electric energy is using a cable, however, this conventional way is not only inefficient but also messy. As the electronic appliances are increased in number, the numbers of cables used are also increased, creating more complicated and messier connection in domestic and daily life. To answer this problem, the application of wireless energy transfer is the solution, by only using the air as the media to transfer energy and adjusting the distance among the appliances and the source([ M. Amato, et.al . vol. 111, pp. 143-148, 2013] [X. Yu, S. Sandhu, S. Beiker, R. Sassoon, Letter 99, vol. 214102, 20]). This means of energy transfer can go through any materials, except bimetal, therefore it can also reach the places where cables application is not possible. This new way of transferring energy is really helpful for human in operating electronic appliances more effectivel The Hybrid Electric Vehicle is a critical technology for achieving a pollution-free world, as gasoline-powered automobiles are the primary source of greenhouse emissions. The current connected charging system has drawbacks such as being costly, cumbersome, unsafe, and inefficient ([R. Butkar, et.al pp. 512-515, Dec 2009] [M. J. Sibakoti, et.al PHY312, Dec 2011]) Furthermore, due to charging-related concerns, consumers do not like the plug-in charging solution for vehicles. The driving circuit is turned ON and OFF by sensing the presence of the vehicle and the basic concept of magnetic resonant coupling is used to send power from the transmitter coil to the reception coil. The wired charging system's constraints are overcome, and maximum efficiency is achieved([C. A. Tucker, et.al , The Un 2013]). If you have an electronic device, such as a cell phone, and you need to charge the battery, you will most likely need to purchase a charger and connect the phone to the cable. That is to say, power will be sent wirelessly. This is made feasible by a technology known as Wireless Power Transmission. Although research and studies have been conducted since the nineteenth century, this notion has only lately begun to be applied That is to say, power will be sent wirelessly. This is made feasible by a technology known as Wireless Power Transmission. Although research and studies have been conducted since the nineteenth century, this notion has only lately begun to be applied. Electromagnetic induction is based on the idea that a primary coil generates a primarily magnetic field, and a secondary coil is positioned inside that field, causing a current to flow through its coils(. Jaysingh KShirsagar et.al 2019). Due to the amount of power necessary to generate an electromagnetic field, this results in a rather short range. The Magnetic Resonant Coupled Wireless Power Transfer System is designed to effectively exchange energy by forming a strong magnetic coupling between two objects adjusted to resonate at the same frequency. Through their fluctuating or oscillating magnetic fields, this phenomenon occurs between the current carrying coils.Some are less efficient and expensive than others, while others do not allow for a larger transmission range. The goal of this innovation is to develop and build an electrical device that can transmit power across a medium range using magnetic resonant coupling. Nikola Tesla in 1889 was the first one who did the research in wireless energy transfer, transferring electric energy from the source to the load without any cables connection. This method of energy transfer is very useful in the places where wired connection is not recommended. This type of energy transfer can be a significant changing in electric field since it will reduce the bronze consumption for conventional cable. This concept is the fundamental of this project, starting from a small energy transfer application, and although the wireless energy transfer already discussed in some references, we propose an easy method to realize this project that can be easily applied in domestic application for home appliances
Summary of the Invention
This gadget may then be used to charge hybrid electric car batteries. As a result, this appropriate approach will be utilized to guarantee that sufficient power is transferred wirelessly so that batteries may be charged. The principle of electromagnetism governs inductive and magnetic coupling (EP2170010B1). A magnetic field creates a magnetic field in a wire when it is in close proximity to one. Inductive coupling is the transfer of energy between wires via magnetic fields.. This technique, when compared to the standard cable transmission method, not only eliminates power loss in the cable transmission process, but also removes transmission line limitations, has broad development possibilities, and has attracted the attention of many experts and academics.
A series of scientific study results have been revealed to the public from the end of the nineteenth century to the present, as scientists continue to enhance their research in this sector. Theoretical development of the following types of power transmission is quite comprehensive at this time: electromagnetic induction wireless transmission; magnetically linked resonant wireless transmission; and wireless transmission based on the microwave concept(US20180240585A1). Electromagnetic induction wireless transmission is the most advanced and has been commercialized among them. This theory underpins the wireless charging of tiny electronic items (such as cell phones and watches) that are ubiquitous in our lives. From the standpoint of wireless transmission principle and application, this innovation will examine the potential development and use of future wireless transmission technologies.
Detailed Description of Invention
In this invention, the main objective of the invention is to generate electricity. Here the Transmitter and Receiver Coils distributes the electric power without the use of conductors as a physically link is referred to as WPT transferring power. The controller sends the power through the driver circuit which is connected for load to consume the power. The transmission of electrical energy without the need of cables as a physical link is known as wireless power transfer (WPT), wireless power transmission (WPT), wireless energy transmission (WET), or electromagnetic power transfer. A transmitter device, powered by electric power from a power source, creates a time-varying electromagnetic field that sends power over space to a reception device, which extracts power from the field and distributes it to an electrical load in a wireless power transmission system. Wireless power transfer technology can reduce the need for wires and batteries, allowing electronic devices to be more mobile, convenient, and safe for all users. Wireless power transmission can be used to power electrical equipment when connecting cables would be cumbersome, dangerous, or impossible. A driver is a circuitry or equipment in semiconductors that controls other circuit or element, including large transistors, liquid crystal display (LCD), variable speed drives, and many more. Generally, the properties of a circuit's driver stage(s) differ from those of other circuit phases.The distribution of electric power without the use of conductors as a physically link is referred to as WPT transferring power. A transmitter device, powered by an electricity source, creates a time-varying electromagnetic field that sends power over space to a reception device that extracts power from the field and distributes it to a load demand in a wireless power transfer system. They're often used to control the flow of current through a circuit or to regulate other factors like other components or devices in the circuit. A specialized integrated circuit that controls high-power switches in switched-mode power converters is sometimes referred to as a high-power switch controller. An amplifier can also serve as a loudspeaker driver or a voltage regulator, allowing a connected component to operate across a wide range of input voltages. The properties of the driver stage(s) of a circuit are often different from those of the other circuit stages. To avoid or reduce distortion in a transistor power amplifier circuit, the driver circuit normally requires current gain, the capacity to rapidly discharge the following transistor bases, and low output impedance. Every day, new technologies develop to make our lives easier. Despite this, we continue to rely on the traditional wire system to replace our low-power gadgets, such as cell phones and digital cameras, as well as mid-power devices, such as laptops. When it comes to charging many devices at the same time, the traditional cable arrangement is a headache. It also consumes a lot of electrical outlets, not to mention the fact that each device's charging connector is unique. In order to prove the effectiveness of our propose method, we conducted experiments for supplying an AC load and a DC load. We limited only one load for each experiment, and we did the experiment for each load in twelve times for different distances
