  • Wireless Power Transmission
    Lecture 8: Supply Systems- Wireless Power Transmission 8.1 Introduction Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which transmits power across space to a receiver device, which extracts power from the field and supplies it to an electrical load. Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible. Figure 8.1 Generic block diagram of a wireless power system. Wireless power techniques mainly fall into two categories, Near field and Far-field. 8.2 Near field Transfer In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes. Inductive coupling is the most widely used wireless technology; its applications include charging handheld devices like phones and electric toothbrushes, RFID tags, and wirelessly charging or continuous wireless power transfer in implantable medical devices like artificial cardiac pacemakers, or electric vehicles. 1 In fact a transformer is transferring energy wirelessly through magnetic field coupling, although it was invented more than 100 years ago. But if you remove the iron core and move the two coils apart, the transfer efficiency drops drastically. That is why the two coils must be put close enough to each other. However, if the transmitter and receiver coils have the same resonant frequency, which is determined by the material and shape of the coil, transfer efficiency will decrease much more slowly when they are moved apart.

  • The Global Wireless Charging Market Size Is Expected to Reach $25.6 Billion by 2026, Rising at a Market Growth of 28.4% CAGR During the Forecast Period
    Source: ReportLinker May 15, 2020 11:58 ET The Global Wireless Charging Market size is expected to reach $25.6 billion by 2026, rising at a market growth of 28.4% CAGR during the forecast period Wireless charging is a system which is efficient, easy and safe for powering and charging electrical devices. In fact, by reducing the use of physical connectors and cables it offers reliable, cost-effective and safer advantages over conventional charging systems. New York, May 15, 2020 (GLOBE NEWSWIRE) -- Reportlinker.com announces the release of the report "Global Wireless Charging Market By Technology By End User By Region, Industry Analysis and Forecast, 2020 - 2026" - https://www.reportlinker.com/p05893269/?utm_source=GNW In fact, it ensures a continuous power transfer to ensure that all types of equipment (handheld industrial devices, heavy-duty devices, smartphone, among others) are charged and readily available to use. Most wireless charging devices employ induction type technology consisting of two main induction coils, one at the charging base, which further addresses the output of an alternating current from the base, and the other at the portable device. These coils take the shape of a pad clipped onto the smartphones. It can be in the shape of an integrated charging coil that attaches to the charging socket and together form an electric transformer. It uses the magnetic coupling phenomenon that the transmitter & receiver coil converts to electrical current for the proper functionality of the inductive power transfer, respectively. The absence of universally accepted specifications and the interaction with other electronic devices act as a barrier to consumer development.

  • A Standard for Wireless Power
    A STANDARD FOR CONTACTLESS ENERGY Lately, the interest in wireless power transmission has considerably increased. However, the range of different technologies used for its realization has led to uncertainly among manufacturers of these devices. This in turn, has delayed the swift, extensive expansion of a wireless charging infrastructure that is indispensable for a market breakthrough in the consumer sector. T E X T: Dr. Stephan Horras F O T O S : RRC Power Solutions www.EuE24.net/PDF/EEK13045930 The use of mobile devices has steadily increased in the past years due to various technological advances. Today, making calls is not one of the primary functions of smart phones. In fact, additional functionalities such as navigation, music players or digital cameras are crucial factors in a consumer’s decision to buy. However, the energy demand of these devices increases with the extended range of functions which, despite the constant advancements in battery technologies, involves more frequent charging. A solution to this problem is the use of wireless power transmission and the creation a widely available charging infrastructure comprised of highly frequented locations, such as for example, car interiors, public institutions and public transportation or cafés. This however implies a manufacturer- independent interoperability between the transmitters and the receivers. In the past few years, the increase in publications and patent applications in the field of wireless power transmission demonstrate the great potential that this topic offers, scientific as well as economic. In 2020, the projected market for mobile devices is 15 billion US dollars of which 5 billion is for the smart phone and cell phone segment [1].
