Technical field
The present invention relates generally to wireless charging, and more particularly, relates to device, the system and method relevant with the wireless power charger.
Background technology
Usually, for example radio communication device (for example, mobile phone) waits each battery powdered device to need its oneself charger and power supply, and described power supply is generally the AC power supplies socket.When many devices need charging when (each device needs its oneself charge independence device), this becomes awkward.
Just developing at reflector and be coupled to and using aerial or wireless power method for transmitting between the receiver of electronic installation to be charged.These a little methods are divided into two classes substantially.One class is based on the coupling of the plane wave radiation (being also referred to as far-field radiation) between the reception antenna on transmitting antenna and the device to be charged.Reception antenna is collected radiation electric power, and radiation electric power is carried out rectification to be used to battery charge.Antenna generally has resonance length, so that improve coupling efficiency.The method suffers the following fact: electric power is coupled and reduces rapidly with the distance between the antenna, makes the charging that surpasses appropriate distance (for example, less than 1 to 2 meter) become difficult.In addition, because emission system radiator plane ripple, so unintended radiation in addition suitably may not disturb other system under the situation of control via filtering.
Other method of wireless energy lift-off technology is based on (for example) and is embedded in the transmitting antenna in " charging " device, pad or the surface and is embedded in inductance coupling high between the reception antenna (adding rectification circuit) in the host electronic to be charged.The method have spacing between transmitting antenna and the reception antenna must be very the shortcoming of nearly (for example, in some thousandths of rice).Though it is the ability of multiple arrangement charging simultaneously that the method has really in the same area, this zone is very little usually, and requires the user to install to navigate to the specific region exactly.
Except that having increased the facility of charging simultaneously, also can solve environment and the cost problem of being paid close attention to by wireless charging.Current, many electronic installations are widely used, and described device is by the normal size powered battery of for example AA, AAA, D, C battery, forms such as 9 volts.These batteries can be primary cell or rechargeable secondary batteries.Primary cell is disposable and increases environmental problem.Rechargeable secondary batteries can help to solve the environmental problem of being paid close attention to, but rechargeable secondary batteries still can remove with charging from device, this can comprise and rechargeable secondary batteries being placed in can only have the battery of the being used for charger of the confined space of (four batteries usually).Because the advantage of wireless power charging, can need and to change (promptly by the existing apparatus of primary cell or secondary cell power supply, remodeling) be wireless, for the device that possesses the wireless power ability to be battery recharge in the wireless charging field or in the wireless charging field, to operate.

Word " exemplary " is in this article in order to expression " serving as example, example or explanation ".The arbitrary embodiment that is described as " exemplary " herein may not be interpreted as more preferred or favourable than other embodiment.
Hereinafter in conjunction with the accompanying drawings and the detailed description of statement is intended to as to the description of one exemplary embodiment of the present invention, and be not intended to expression and can put into practice the embodiment that only has of the present invention.Run through this and describe employed term " exemplary " expression and " serve as example, example or explanation ", and may not be interpreted as more preferred or favourable than other one exemplary embodiment.Described detailed description is for providing the purpose of the thorough of one exemplary embodiment of the present invention and comprise specific detail.Those skilled in the art will realize that and under the situation of not having these specific detail, to put into practice one exemplary embodiment of the present invention.In some instances, show well-known structure and device, to avoid the novelty of the fuzzy one exemplary embodiment that presents herein with the block diagram form.
Word " wireless power " in this article in order to be illustrated under the situation of not using the physical electromagnetic conductor be transmitted into receiver from reflector with electric field, magnetic field, electromagnetic field or other any type of energy that is associated.
Fig. 1 explanation is according to the wireless transmission or the charging system 100 of various one exemplary embodiment of the present invention.Input electric power 102 is provided to reflector 104 is used to provide the energy transmission for generation radiation field 106.Receiver 108 is coupled to radiation field 106, and produces output power 110 for being stored or consumed by the device that is coupled to output power 110 (not shown).Reflector 104 and receiver 108 both partition distance 112.In an one exemplary embodiment, concern according to mutual resonance and to dispose reflector 104 and receiver 108, and when the resonance frequency of the resonance frequency of receiver 108 and reflector 104 is identical, when receiver 108 was arranged in " near field " of radiation field 106, the launch loss between reflector 104 and the receiver 108 was minimum.
Fig. 2 shows the rough schematic view of wireless power transfer system.Reflector 104 comprises oscillator 122, power amplifier 124 and filter and match circuit 126.Described oscillator is configured to produce oscillator signal under want frequency, can adjust the described frequency of wanting in response to adjusting signal 123.Can amplify oscillator signal in response to control signal 125 with an amplification quantity by power amplifier 124.Filter and match circuit 126 be can comprise with filtering harmonic wave or other non-desired frequency, and the impedance and transmitting antenna 114 couplings of reflector 104 made.。
As illustrated among Fig. 3 A, employed antenna can be configured to " annular " antenna 150 in the one exemplary embodiment, and it also can be described as " magnetic " antenna in this article.Loop aerial can be configured to comprise air-core (air core) or physics core (physical core) (for example, ferrite core).The air-core loop aerial can be allowed near the external physical unit that is positioned over the described core better.In addition, the air-core loop aerial allows other assembly to be positioned in the core zone.In addition, the air-core ring can be easier to make it possible to reception antenna 118 (Fig. 2) is positioned in the plane of transmitting antenna 114 (Fig. 2), and at place, described plane, the coupled mode district of transmitting antenna 114 (Fig. 2) can be more powerful.
Such as statement, the high efficiency energy between reflector 104 and the receiver 108 be transmitted between reflector 104 and the receiver 108 coupling or near the coupling resonance during take place.Yet,, also can inefficiently transmit energy even when the resonance between reflector 104 and receiver 108 does not match.Energy transmits that energy by the near field of spontaneous emission in future antenna is coupled to the reception antenna that resides in the neighborhood of having set up the near field but not energy is propagated into the free space from transmitting antenna and takes place.
The resonance frequency of annular or magnetic antenna is based on inductance and electric capacity.Inductance in the loop aerial is generally the inductance that is produced by ring, and adds electric capacity the inductance of loop aerial to produce resonance structure under wanted resonance frequency usually.As limiting examples, can add capacitor 152 and capacitor 154 to described antenna, to form the resonant circuit that produces resonance signal 156.Therefore, for larger-diameter loop aerial, the size of bringing out the required electric capacity of resonance increases along with the diameter of ring or inductance and reduces.In addition, the diameter along with loop aerial or magnetic antenna increases the high efficiency energy transit area increase near field.Certainly, other resonant circuit is possible.As another limiting examples, capacitor can be positioned between two terminals of loop aerial concurrently.In addition, those skilled in the art will realize that resonance signal 156 can be the input of loop aerial 150 for transmitting antenna.

One exemplary embodiment of the present invention is included in coupling electrical power between two antennas in the near field that is in each other.Such as statement, the near field be around the antenna wherein electromagnetic field exist but may not propagate or radiation away from the zone of described antenna.The near field is defined in the volume near the physical size of described antenna usually.In one exemplary embodiment of the present invention, magnetic type antenna (for example, single turn loop aerial and multiturn loop aerial) be used for emission (Tx) antenna system and reception (Rx) antenna system both, because with electric type antenna (for example, small-sized dipole antenna) electrical near field is compared, the magnetic near field amplitude of magnetic type antenna trends towards higher, thereby allows described to the potential higher coupling between the antenna.Yet the combination of " electrically " antenna (for example, dipole and one pole) or magnetic antenna and electrical antenna also is contemplated within the scope of the invention.
The Tx antenna can operated under the enough low frequency and under the enough big situation of antenna size, with the good coupling that under remarkable distance, is implemented to small-sized Rx antenna greater than the distance that is allowed by previous far field of being mentioned and inductance method (for example,＞-4dB).If the size of Tx antenna is through correct design, so in the time the Rx antenna on the host apparatus being positioned in the coupled mode district that is driven the Tx loop aerial (that is, in the near field), can realize high coupling level (for example ,-1dB to-4dB).
In the future can make the electronic installation that is built in wireless power and/or the NFC in the electronic installation.Yet many electronic installations are widely used, and it uses conventional disposable or rechargeable battery, and described battery does not have the wireless power ability, and it does not have the NFC ability.Embodiments of the invention comprise the embodiment of the electronic installation of retrofiting, and described electronic installation is not built-in at first wireless power technology or NFC, but these traditional electronic devices exist with the user.These a little embodiment can comprise that shell is replaced in customization battery pack, customization, the standard cell group etc. of retrofiting.
