Of course, it is noted that the components illustrated in the drawings and below may be partially changed or adjusted as an example within the scope of the present invention.

The configuration system of the present invention is roughly divided into a wireless power transmission system and a wireless power reception system.

Mobile communication devices, portable audio devices, portable TVs, portable mobile computers, electric vehicles, trains, ships, aircraft, and other mobile devices that use batteries as main power, or devices in areas where it is difficult to establish wired power supply lines. As a construction of a transmission system for wirelessly supplying power energy required for use or operation of a device,

First, as shown in Figure 1, the adapter 110 converts power from AC 100 to DC 120 and the available voltage required to use the mobile device to convert the power to DC (eg 1.5V, 3V, 9V, etc.), the distribution device 130 to distribute evenly, the converter 140 for converting these distributed power into radio waves and the power-wave propagation 150 of the transmitter converted to radio waves are used in the mobile device. Or a transmission system comprising a synthesizer 150 to be loaded on or included in a normal data transmission / reception frequency and a transmitter 160 for transmitting these synthesized radio waves; or

Secondly, an adapter device for converting power from AC to DC, a device for converting power converted from DC to radio waves, and a device for distributing DC power radio waves into radio waves with available voltages required for use in portable equipment, and moving these power waves A method of constructing a transmission system for transmitting these radio waves combined with a means device which is loaded on or included in a normal data transmission / reception frequency in use in the apparatus device, or

Third, a device for converting AC power into radio power radio waves, a means device for loading or embedding power radio waves converted into radio waves on an available frequency for normal data transmission and reception, and a transmission system for transmitting these radio waves. The intermediate process between the AC 100 and the power propagation wave 150 may be changed or adjusted later according to a transmission method, and thus no particular limitation is imposed thereon.

In addition, the receiving system for receiving wireless power includes a receiving unit 200 for receiving a radio wave including a power source radio wave, a separating unit 210 for separating the power source radio wave 220 and the natural frequency 250 for transmitting and receiving the normal data of the receiver. And a receiver system configured to convert the separated power supply wave 220 of the receiver back into the direct current 240. Of course, the power converted to the direct current 240 is used for charging the battery of the mobile device device or operation of the device.

In addition, according to the ON A CHIP method, the system for transmitting / receiving a power supply wave of the present invention may partially integrate some processes illustrated in the drawings into one subsystem form, and in this case, Of course it belongs to the category.

And when the power energy is supplied from the radio wave containing the power according to the present invention,

First, when the state of charge of the battery of the user's mobile device reaches a certain level, power is supplied via intermittent power waves as needed.

That is, when the state of charge of the battery is checked in the mobile device itself, and when the state of charge is below a certain level, it is determined that additional power is required, and when the mobile device itself or the user sends a wireless power supply request signal to the transmitting station. The transmitting station continuously transmits a radio wave containing power to the mobile device until the full charge signal of the mobile device battery is reached.

Secondly, power is continuously supplied through power propagation throughout the period of use of the mobile device itself or in response to a user's request signal, which is at least constant for the first communication of the mobile device with the transmitting station during operation. A small primary battery with a level of power is required, which can then be charged by the power propagation signal transmitted from the transmitting station and can be used continuously. In addition, when the main battery is completely discharged or there is no power, it can also be charged using the AC or DC that is being used nearby. To continue to be powered by

Third, it is operated by a power company having a separate frequency in a manner by a wireless power dedicated transmission system for the purpose of supplying wireless power, which is a system that transmits wireless power on a separate frequency, The user may set the frequency of the mobile device to the corresponding frequency and receive power.

In addition, when the high-voltage high-voltage electrical energy is to be transmitted and received in a wireless manner, a method of dividing and transmitting the high-voltage voltage into multiple low-frequency types may be used to divide and transmit the signal to multiple frequencies. A device is added that integrates the true power energy into one power source. In other words, if you want to transmit and receive electric energy of a relatively high voltage such as electric vehicle by wireless method, it is also possible to divide the 24V used for automobile into 6V form and divide and transmit by 4 lines of frequency. The power supply can transmit and receive as much as this way. In this case as well, a device for integrating the power energy carried in the frequency divided into several lines into one power source is added.

The power supplied to the mobile communication device, the portable audio device, and the portable TV is transmitted and received by loading or synthesizing a power-wave which converts the power into an electric wave to an inherent dedicated electric wave used in the device. The power supply to the vehicle can be continuously supplied with wireless power energy regardless of the place, for example, through a separate wireless power reception device mounted on a vehicle or an interface connected to a mobile communication device. In addition, the power supply method of the mobile computer can continuously supply power through a wireless transmission / reception system such as a wireless modem installed in a mobile computer or a mobile communication device connected to a separate interface device, or a separate wireless transmission / reception system of its own built-in type.

Recently, a method using a laser beam has also been put into practice in various data transmission / reception methods such as an image, a sound, a character, a code, and the like. It can be fully implemented, and it is possible to simultaneously transmit and receive various data and power wirelessly by infrared method, Bluetooth method, USB method, LAN method or WAN method and separately designated wireless transmission / reception method.

In addition, when wireless power is transmitted to these portable device devices or mobile transportation means, a separate interface may be installed to connect the mobile device devices to supply power to other device devices other than the corresponding device device.

In addition, the power source radio wave including the electric power can be applied according to the intended use within the range of a normal radio wave, but the frequency range can be adjusted according to the future use, and in particular, according to the spirit of the present invention, The kind of radio waves is not limited. In addition, a power company that supplies separate wireless power, a communication company that manages various frequencies, a broadcaster, etc., a wireless power receiver installed in a user's mobile device or a vehicle such as an electric vehicle using a power source radio wave containing power energy It consists of an operating system that can manage the frequency of the radio frequency and charge according to the radio wave usage including the power.

The radio wave system for wireless power transmission and reception of the present invention has a problem of supplying power energy required for use or operation of existing mobile communication devices, portable audio devices, portable TVs, mobile computers, electric vehicles, trains, ships, aircrafts, and other mobile device devices. As a solution to this problem, the battery device of these device devices can be reduced, miniaturized or omitted, so that the mobile device device can be lighter, lighter, and shorter, and the necessary power can be continuously supplied, no matter how far. Since the electric wave can be transmitted wirelessly to a place where the radio wave is far from a remote place, there is an advantage that it is not restricted in the place and time of using various apparatus devices.

In addition, since the DC type idle power used in the present invention can be stored and wireless power energy is supplied in accordance with the power request signal of the mobile device, there is no waste of unnecessary power, and the equipment or installation of the wireless power transmission system can be used. Even if the existing frequency band, transmission system and base station can be used as it is, it is possible to minimize the investment cost for the additional construction of a separate transmission facility or base station.
