Background
More than a century after the inventor Nikola Tesla laid the foundations of wireless electricity, the progress made since then validates the possibility of its technology Although the first theoretical bases of wireless electricity (wireless electricity or witricity) come from the early nineteenth century, with the demonstration of magnetic fields generated from current or the formulation of the law of induction, Tesla was the first to apply this knowledge, conducting experiments where energy was transported without wires.
This technology, which has long been considered a myth, was baptized as the Tesla effect, whose inventor proposed the possibility of supplying energy to the entire planet, as if it were a universal Wi-Fi network. The lack of funding frustrated that colossal project, but Tesla's dream has been kept alive ever since, generating throughout the 20th and 21st centuries a vast scientific bibliography, which in recent years has begun to crystallize in real applications.
Current status
The transfer of electrical energy by inductive coupling is known in the state of the art. An inverter transforms an input DC voltage into a high frequency AC voltage, this high frequency AC voltage feeds a primary coil or transmitter coil which due to the time-varying magnetic field induces a voltage in a secondary coil or receiver coil The secondary coil is adjusted to the resonant frequency by using capacitors achieving maximum power transfer and maximum efficiency.
The transmission of electrical energy without the use of cables is already a reality.
Inductively coupled power transfer systems are currently available for small distances, in the order of a few centimeters. The main current devices include induction chargers for cell phones that allow power transfer of up to 5 W at distances of up to 4 cm.
SHS Solution
SMART HOME SOLUTIONS, S.L. has succeeded in developing a Long distance wireless power supply system which allows powering medium power electrical and electronic devices for domestic use.
The system is based on a magnetic resonant coupling for power supply of electrical devices up to 400 W consumption with distances up to 10 meters without the need to use cables or batteries to power these devices.
The magnetic field passes through solids and liquids and is safe for health.
This type of system can be used to power electrical and electronic devices such as televisions, light bulbs, blenders, video game consoles, chargers, etc., which are not elements that have batteries to operate but are constantly connected to the mains.
The main reason for using this technology is to eliminate cables and connectors and to provide a safe, transparent and user-friendly power supply system.
The system consists of a grid-connected transmitter consisting of an inverter circuit connected to a resonator tank and a transmitter coil, and a receiver consisting of a receiver coil connected to a resonator tank and optionally to a rectifier.
The system is powered by alternating current (AC) and is converted to direct current (DC) by means of a Rectifier. To transfer the electrical energy, an inverter connected to a resonator tank is used to transform the input DC voltage into an AC signal in a frequency band from 100 KHz to 500 KHz. This AC voltage feeds an emitter coil which produces a magnetic flux that induces a voltage in one or more receiver coils. Thus, the higher the magnetic flux, the more voltage induced in the receiver coil will be obtained.
This system is ideal for powering electrical and electronic devices with a power equal to or less than 400 W such as a blender, a juicer, a TV, a computer, a printer, a lamp, etc. Some of them operate with an alternating voltage of 220 V/ 50 Hz and others can operate with a direct voltage source. To ensure the power supply for equipment operating on DC voltage, a full-wave rectifier has been designed at the output to supply the device with a DC voltage with a maximum ripple of 5%.
Does it affect the human being?
In the system that has been designed, for magnetic induction to occur, the receiving ring must resonate at the same frequency as the transmitter. For this reason, surrounding objects that are not in resonance would not be affected by the generated magnetic field.
The human body actually responds to electric fields but it does not respond to magnetic fields. The human body has a response to the magnetic field in terms of absorbed energy almost equal to zero.
More than 25,000 studies have been conducted on the health effects of magnetic fields, which have shown that it is a completely safe technology with no effects on the human body, as stated by the WHO (World Health Organization). Radiation: Electromagnetic Fields
In addition, SHS has so far made a great effort to ensure the safety of the technology in health.
SHS technology is completely safe and complies with all current regulatory and safety standards.
SHS aims to improve the quality of life of users of implants with electronic components, and to open up the possibility of developing new types of implants.
Social impact
The social impact of the technology developed by SHS will come through the creation of new production and industrial lines.
This technology is expected to make a very significant breakthrough in terms of becoming the new market reference, thus allowing a totally national technology to penetrate such an innovative market.
In addition, the impact at the consumer level is very appreciable in terms of the great convenience and versatility that this technological solution provides by eliminating cables and batteries in day-to-day life.
Additionally, it is worth mentioning the consequent creation of direct and indirect jobs, and through the added value in terms of convenience for users of electrical and electronic equipment without wiring.
Environmental impact
The environmental impact of this technology is mainly found in the elimination of wiring of electrical and electronic components used outdoors, reducing the environmental and visual impact of the wiring as well as the overall environmental footprint and waste generation from cable degradation.
In addition, the use of this technology will promote the use of rechargeable batteries instead of single-use batteries, as well as the decrease in the consumption of plastic and copper for wiring, with the consequent reduction in the generation of highly polluting waste.
