技术领域 FIELD

该发明涉及一种用于以无接触的方式传输电能的新装置和方法。 The invention relates to a novel apparatus and method for contact-free manner for transmitting electrical energy.

背景技术 Background technique

当今许多便携式设备结合了可以重复充电的"辅助"电池,为用户节省了成本,并免除了不得不定期购买新电池所带来的不便。 Many of today's portable devices can be recharged in conjunction with the "ancillary" battery, to save costs, and eliminates the inconvenience to regularly buy a new battery brings. 这些便携式设备的例子包括蜂窝电话、膝上型计算机、掌上500系列的个人数字助理、电动剃须刀以及电动牙刷。 Examples of these portable devices including cellular phones, laptop computers, handheld 500 series personal digital assistant, electric shavers and electric toothbrushes. 在一些这样的设备中,电池通过电感耦合而不是直接电连接进行重复充电。 In some such devices, the battery connection rechargeable by inductive coupling rather than a direct electrical connection. 这样的例子包4舌Braim Oral B的Plak Control电动牙刷、Panasonic的凄丈字无绳电话解决方案KX-PH15AL以及Panasonic的多头男士剃须刀ES70/40系列。 Examples of such packages tongue 4 Braim Oral B Plak Control of the electric toothbrush, the Panasonic digital cordless telephony sad husband solution and Panasonic KX-PH15AL men's razor bull ES70 / 40 series.

每一种这样的设备通常具有一个适配器或充电器,该适配器或充电器乂人电源供应的电力、汽车香烟打火才几或其它电源获取电能,并将其转换成一种适于对蓄电池进行充电的形式。 Each of these devices typically has an adapter or charger, the adapter or charger power supply qe human power, only a few car cigarette or other ignition power draw power, and converts it into a battery adapted to be charged form. 为这些设备提供电力或充电所采用的传统方法存在许多问题: There are many problems to provide power or charging equipment used for these conventional methods:

•各个设备内的电池的特性和与电池连接的方法根据制造商和设备的不同,变化相当大。 • characteristics of a battery in the apparatus and method of each connected to the battery depending on the manufacturer and equipment vary considerably. 所以拥有几种这样的设备的用户也必须拥有几种不同的适配器。 So users have several such devices must also have several different adapters. 如果用户打算出门旅行并且希望在这段时间使用他们的设备,他们将不得不带上他们所有的充电器。 If you plan to travel and want to use their devices during this time, they will have to bring all their chargers.

•这些适配器和充电器常常要求用户把一个小的连接器插入设备或将设备精确校准放入机座中,这造成不便。 • These adapters and chargers often requires the user to a small connector into the machine, or stand placed in precise alignment, which causes inconvenience. 如果用户未能将他们的设备插入或放入到充电器中且设备已用完了电,该设备将变得毫无用处,且本地存储在设备中的重要数据甚至可能会丢失。 If the user fails to insert their device into the charger or into the device and have run out of power, the device will be rendered useless, and important data stored locally on the device may even be lost.

•另外,大多数的适配器和充电器不得不插入电源插座内,所以如果几个适配器和充电器一起^f吏用,它们将占用插座条的空间,且造成电线凌乱并且混乱地纠缠在一起。 • In addition, most adapters and chargers have to be inserted into a power outlet, so if several adapters and chargers ^ f together with the officials, they will take up space strip, and clutter and confusion caused by wires intertwined.

•除了对i殳备重新充电的传统方法带来的上述问题之外,具有开放式电触点的设备也存在许多实际的问题。 • In addition to the above-described problems of the conventional method i Shu brought recharging apparatus, having an open electrical contact device there are many practical problems. 例如,由于可能腐蚀触点或^f吏触点短^各,i殳备不能用于潮湿的环境中,并且由于可能产生电火花,设备也不能用于可燃气体环境中。 For example, due to possible corrosion of the contacts or short ^ F ^ lai respective contacts, I Shu apparatus can not be used in humid environments, and since the spark may be generated, the device can not be used in flammable gaseous environments.

使用感应充电的充电器不需要具有开放式电触点,因此使得适配器和设备可进行密封且用于潮湿的环境(例如上面提到的电动牙刷被设计用于浴室中)。 Using inductive charging charger need not have open electrical contacts, and so that the adapter device can be sealed and used in wet environments (e.g., a power toothbrush mentioned above is designed for bathroom). 然而,这种充电器仍然面临上述的所有其它问题。 However, this charger is still facing all the other problems mentioned above. 例如,设备仍需要精确地》大置在充电器中,4吏得设备和充 For example, the device is still necessary to accurately "Great placed in the charger, and the charging device 4 to give officials

电器处于预定的相对位置(参见图la和图lb)。 The appliance is in a predetermined relative position (see FIGS. La and lb). 适配器仍然积J义被设计为专用于某种构造和类型的设备,且仍然仅仅能够每次对一个设备进行充电。 J-defined product remains adapter is designed to be dedicated to a certain type and configuration of equipment, and still only be able to charge the device one at a time. 结果,用户仍然需要拥有和管理多个不同的适配器。 As a result, users still need to own and manage a number of different adapters.

同样存在有通用型充电器(例如Maha MH-C777 +通用充电器),使得不同形状和特性的电池组可以从设备中取下,且使用同一个设备进行充电。 Also there universal charger (e.g. Maha MH-C777 + universal charger), so that the battery pack and the characteristics of different shapes can be removed from the device, and a device using the same charge. 虽然这些通用充电器消除了拥有用于不同设备的不同充电器的必要性,但它们给用户产生了甚至更大的不便,这是因为电池组首先需要被取下,然后需要对充电器进行调整,并且电池组需要被精确地放入充电器或相对充电器进行放置。 Although these universal charger eliminates the need to have different chargers for different devices, but they had to the user even greater inconvenience, because the battery needs to be removed first, and then need to be adjusted charger , and the battery pack needs to be placed accurately relative to the charger or the charger disposed. 另外,必须花费时间来确定充电器所必须4吏用的一对正确的电池组金属触点。 Further, the charger must spend time must be determined using a 4 officials battery correct set of metallic contacts.

从WO 00/61400 "用于感应传送电能的设备(Device for Inductively Transmitting Electrical Power ),, 了解到,其4是供了一种才巴电能感应地转移给传送装置的方法。 From WO 00/61400 "for the inductive power transfer device (Device for Inductively Transmitting Electrical Power) ,, learned, which is for a 4 bar before transferring power inductively to the method of delivery device.

乂人WO 95/11545 "感应式电能获耳又线圈(Inductive power pick-up coils)" 了解到,其提供了一种用于从一系列的内置扁平初级线圈为电动交通工具感应地4是供电能的系统。 Qe al WO 95/11545 "eligible ear and inductive power coil (Inductive power pick-up coils)" learned, provides for an electric vehicle built from a series of flat primary coil 4 is inductively powered energy system.

为了克服要求次级装置与初级装置轴向对准的感应式电能转移系统的局限性,可能有人会提出一个显而易见的解决方案,即使用一个简单的感应电能转移系统,借助该系统初级装置能够在l交大区域内发射电》兹场(参见图2a)。 To overcome the limitations of the system requires a secondary device and the primary inductive power transfer means axially aligned, some may raise an obvious solution, i.e. the use of a simple inductive power transfer system, the primary system by means of which the apparatus can National Chiao Tung University emission region within l "hereby field (see FIG. 2a). 用户可以筒单地把一个或多个待充电的设备放置在初级装置的范围内,而不要求把它们精确放置。 The user can put a single cylinder or a plurality of charging devices to be placed within range of the primary device, without requiring the precise placement thereof. 例如,这个初级装置可以包括一个环绕较大区域的线圈。 For example, this means may comprise a primary coil encircling a large area. 当电流流经线圈时,产生了在较大区域范围延伸的电磁场,设备可以放置在该区域内的任何位置。 When the current flows through the coil, an electromagnetic field is generated in a large area extended range, the device may be placed at any position within the region. 虽然该方法理论上可行,但其具有很多缺陷。 Although this method is theoretically feasible, but it has many drawbacks. 首先,电》兹发射的强度受调节范围所控制。 First, electric "hereby emission intensity is controlled by the adjustment range. 这意味着该方法^U义支持有限速率的电能转移。 This means that the method ^ U righteous support a limited rate of energy transfer. 另外,许多物体可能受到强磁场的存在的影响。 Furthermore, many objects may be affected by the presence of a strong magnetic field. 例如,存储在信用卡上的数据可能一皮毁坏,并且金属制成的物体内部将感应生成涡电流,从而产生不希望的加热效果。 For example, data stored on a credit card may destroy the skin, and made of a metal object inside the induced eddy current is generated, resulting in undesirable heating effect. 另夕卜, Another evening Bu,

ii如果包括传统线圈(参见图2a)的次级装置与诸如印刷电路板内的铜板或电池的金属外壳相对放置,耦合可能显著地降低。 If the coil comprises a conventional ii (see FIG. 2a) and a secondary device such as a copper plate or a metal case of the battery within the printed circuit board is placed opposite the coupling may be significantly reduced.

为了避免产生大的磁场,可能有人建议使用线圏阵列,借助该线圈阵列只有所需的线圏^皮激活(参见图3)。 In order to avoid a large magnetic field, it may be an array of rings of wire been suggested, by means of which only the desired line coil array transdermal ^ rings of activation (see FIG. 3). 该方法在日本》兹学学会期刊上2001年11月29日发表的题为"台式无4妄触电站系统内的纟戋圈形习犬(Coil Shape in Desk-type Contactless Power Station Syetem)"的论文中进行了描述。 The method in Japan, "the journal Society is hereby published November 29, 2001, entitled" Si no desktop constricted ring-shaped habit Dog (Coil Shape in Desk-type Contactless Power Station Syetem) 4 jump in shock station system " the paper described. 在多线圈原理的一个实施例中, 传感机构对次级装置相对于初级装置的相对位置进行检测。 In one embodiment of the multi coil principle, the sensing mechanism detects the secondary device relative position of the primary device. 然后, 控制系统激活相应的线圏以定位方式把电能传送给次级装置。 Then, the control system activates the appropriate manner to position the wire rings of the transmitted power to the secondary device. 虽然该方法提供了一种之前所列出的问题的解决方案,l旦是实现起来既复杂又昂贵。 Solution to the problem before While this method provides a listed, l Dan is complex and expensive to implement. 初级场可被定位的程度受线圈数量的限制,因此也受所使用的驱动电路的数量的限制(也就是初级装置的"分解,,)。多线圈系统的成本将大大限制该原理的商业应用。场分布不均匀也是一个缺陷。当初级装置内的所有线圈都被激活时,它们合起来等价于一个大线圈,它的》兹场分布在线圈的中心显示为最小。 Degree can be positioned by the primary field coil limitation of quantity, and therefore limited number of drive circuits to be used (i.e., "primary device ,, decomposition). The cost of a multi-coil system would greatly limit the commercial applications of the principles of the the field is the uneven distribution of a defect. when all the coils within the primary means are activated, which together are equivalent to a large coil, its "field distribution in the center of the coil hereby display is minimized.

另一方案在US 5,519,262"近场电能耦合系统(Near Field Power Coupling System)"中加以概述,其中初级装置具有大量从扁平板的一端到另一端布置的窄感应线圈(或可选;也电容4反),产生大量以相4立移的方式进4亍驱动的垂直场,而佳J寻运动正弦波在^反上移动。 Another aspect to be outlined in US 5,519,262 "near-field power coupling system (Near Field Power Coupling System)" in which the primary device arrangement having a large number of the flat plate from an end to another end of a narrow induction coil (or alternatively; also 4 anti-capacitance), a large amount of relative shift of the 4 vertical manner into 4 vertical field driving the right foot, J kai moved in the sinusoidal motion seeking anti ^. 接收设备布置有两个垂直的场接收装置,使得无论该接收设备位于板上的什么位置,它总能从至少一个接收装置收集到电能。 The receiving device is arranged with two vertical field receiving apparatus, so that no matter where the plate receiving apparatus is located, it is always received from the at least one device for collecting the electric energy. 虽然该方案也给设备提供移动的自由,但是它有一些缺点在于需要一个复杂的次级装置、具有一个固定的分解以及由于返回^兹通^各径是通过空气而耦合4交差。 Although the program can provide free movement to the device, but it has some disadvantages that it requires a complicated secondary device, having a fixed return and due to decomposition of the through ^ ^ hereby air through each path is cross coupling 4.

现有4支术的解决方案都不能令人满意地解决已描述的所有问题。 Existing four surgery solutions do not satisfactorily solve all the problems have been described. 如果能获得一个能以以下所有特征向便携式设备转移电能、并且能以划算的成本实施的解决方案,将是很令人满意的:*通用性:单一初级装置,它可以为具有不同电能要求的不同次级装置提供电力,从而消除了多个不同的适配器和充电器的必要 Can be obtained if a solution can be all of the following features to transfer electrical energy to the portable device, and can be implemented in a cost-effective, it would be desirable: * GM: primary single device, which may have different power requirements different secondary device to provide power, thereby eliminating a plurality of different adapters and chargers necessary

•用于不同环境的灵活性:单一初级装置,它可以为次级装置才是供电力,而不要求直接的电4妄触,乂人而允许次级装置和初级装置自身可用于潮湿的、含有气体的、清洁的和其它不正常的环境; • flexibility for different environments: a single primary device, it is possible for a secondary power unit, without requiring a direct electrical contact jump to 4, person qe allow the secondary device and the primary unit itself may be used wet, containing gas, cleaning, and other abnormal environment;

•低电磁发射:单一初级装置,它可以将产生的磁场的强度和大小降低到最低的方式传送电能。 • Low electromagnetic emissions: a single primary means to reduce the size and strength of the magnetic field which can be generated by energy transfer to the lowest way.

此外可理解,便携式设备正大量产生,它们都需要电池给它们冲是供电能。 Further appreciated, a large number of portable devices are produced, they require battery power is able to punch them. 原电池或其电池组用完后必须进4亍处理,这既昂贵又污染环境。 Primary battery or a battery pack to be exhausted into the process right foot 4, which is both expensive and pollute the environment. 而蓄电池或蓄电池纟且可以进4亍充电且重复<吏用。 The battery or batteries and may be Si and repeatedly charged into the right foot 4 <official use.

许多便携式设备具有装满足工业标准大小和电压的诸如AA、 AAA、 C、 D和PP3的电池的容器。 Many portable devices having means to meet industry standards, such as size and voltage of the AA, AAA, C, D, and PP3 battery container. 这使得用户能够自由选择是否4吏用原电池或蓄电池以及不同的类型的电池。 This enables the user to freely choose whether to 4 with a primary battery or secondary battery officials and different types of batteries. 一旦用完,通常必须将蓄电池从设备中取下并放置到单独的充电装置中。 Once exhausted, the battery must generally be removed from the device and placed into a separate charging device. 或者, 一些便携式设备具有内置的充电电^各,允许电池在设备插入外部电源时就地进行充电。 Alternatively, some portable device has a built-in charging each ^ allow in situ charging the battery when the device is inserted into the external power source. 对于用户来说,必须把电池从设备中取下以进行充电或把设备插入外部电源来原地进行充电,这都是不方便的。 For users, it is necessary to remove the battery from the device or to charge the device inserted into the external power source is charged in situ, this is inconvenient. 最好能通过某种非接触方式对电池进行充电,而不必进行上述任何操作。 Preferably non-contact manner by some charge the battery, without having to perform any such operation.

这种设计的根本改变克服了传统系统的至少一个缺陷。 Overcome this fundamental change in the design of the traditional system of at least one defect. 所提出的发明的好处包4舌: Benefits of the proposed invention tongue package 4:

•不需要4青确的对准:次级装置可以;故置在初级装置的充电区域上的任何位置; • No correct alignment of Green 4: secondary device can; it is placed on the charging device of any region of the primary position;

,耦合均匀:在所提出的发明中,初级装置和次级装置之间的l禺合在充电区i或上与传统的初级线圈和次级线圈相比更力口均匀。 Coupled uniformity: In the proposed invention, l Yu means between the primary and secondary engagement means compared with a conventional primary and secondary coils in the charging region i or more opening force uniform. 在传统的大线圈系统(参见图2a)中,场强在线圈平面内的线圈的中央降到最小(参见图2b)。 In conventional large coil system (see FIG. 2a), the field strength in the central plane of the coil to minimize coil (see FIG. 2b). 这意味着如果足够的电能在中央位置能被有效地转移,那么最小场强必须高于某一门限值。 This means that if sufficient energy can be effectively transferred in a central position, then the minimum field strength must be above a certain threshold value. 那么最大场强将大大高于所要求的门限值,这可能导致不希望的结果。 Then the maximum field strength is much higher than the required threshold, which could lead to undesirable results.

•通用性:多个不同的次级装置,甚至那些具有不同功率要求的设备,都可以放置在初级装置的充电表面上的充电区域内来同时接收电能。 • GM: a plurality of different secondary devices, even those devices with different power requirements, can be placed on the charging surface of the primary charging device regions simultaneously receive power. •耦合系数提高:次级装置内的可选的高导磁率》兹性材料通过 • coupling coefficient to improve: the optional high permeability "within the secondary material by means hereby

提供一条低磁阻路径大大增加了感应产生的磁通量。 Providing a low reluctance path greatly increases the magnetic flux generated by the induction. 这可以极大地增加电能转移。 This can greatly increase the power transfer.

•适于次级装置的理想形状因子:本系统的几何形状允许使用薄片状磁性材料(例如非晶金属带)。 • means adapted over the secondary shape factor: the geometry of the system allows the use of a sheet material (such as an amorphous metal strip). 这意味着次级装置可以具有薄片状的形状因子,使得它适于装在移动电话和其它电子设备的后部。 This means that the form factor of the secondary device may have a sheet-like, such that it is adapted to be mounted at the rear of the mobile phone and other electronic devices. 如果在传统线圈的中央4吏用f兹性材料,有可能增加次级装置的体积。 If the central hereby f 4 officials with conventional coil material, it is possible to increase the volume of the secondary device.

•场泄漏最小:当一个或多个次级装置存在于初级装置的充电区域内时,有可能以这种方式使用磁性材料,即使得超过一半的》兹路为低;兹阻材料(参见图4d)。 • Minimum field leak: when one or more secondary devices present in the region of the primary charging means, it is possible to use a magnetic material in this manner, even when more than half of the available "low hereby path; hereby barrier material (see FIG. 4d). 这意味着对于特定的;兹动势(magneto-motive force, mmf) 4夸有更多的不兹力线5危入。 This means that for a particular; 4 boast hereby motive force (magneto-motive force, mmf) hereby no more risk into the line of force 5. 由于感应电压与所耦合的磁通量的变化率成比例,这将使转移到次级装置的电能增加。 Since the rate of change of the induced voltage is proportional to the magnetic flux coupled, which will allow transfer of power to the secondary device is increased. ^^各中的空气间隙越少并且越短,场的边缘越少,则磁力线离初级装置的表面越近,所以泄漏也最小。 The smaller the air gap and in each ^^ shorter fewer fringe field, the magnetic lines of force nearer the surface of the primary device, the leakage is minimal.

•成本高效:与多线圈^:计不同,本发明的解决方案要求更为 • cost-effective: the multi-coil ^: different terms, the inventive solution requires more

简单的控制系统和更少的部件。 Simple control system and fewer components.

•次级装置的自由绕轴旋转:如果次级装置是薄片状或可选地甚至是圆柱状(参见图10),可以这样对其进行构造,使它保持与磁力线的良好耦合,而不管它是否围绕最长轴进行旋转。 • free rotation about the axis of the secondary device: If the secondary device is a sheet-shaped or alternatively even be cylindrical (see FIG. 10) may be configured so that it remains a good coupling with the magnetic field lines, regardless whether rotate around the longest axis. 如果次级装置是一个安装在另一i殳备内的电池组电池,当次级装置的绕轴旋转可能难以控制时,这可能尤其是一个优点。 If a secondary device is another battery cell i Shu in the mounting apparatus, when the rotation about the axis of the secondary device may be difficult to control, which may be a particular advantage.

•次级装置内的磁芯可以设置为位于该设备内或设备附近的其它平行金属平面的附近,例如位于铜印刷电路板或铝盖的附近。 • the core inner secondary device may be provided within the apparatus or located near the other parallel to the metal plane in the vicinity of the device, for example a printed circuit board is located in a copper or aluminum cap. 在这种情况下,本发明的实施例的性能大大优于传统绕芯 In this case, the performance of an embodiment of the present invention is much better than traditional winding core

24缠绕的线圏的性能,这是因为如果传统设备线圈面向金属平面放置,穿过传统设备线圈的场线将遭受磁力线排斥(因为磁力线必须垂直于线圈平面传播)。 Rings of wire 24 wound performance, because if conventional coil device is placed facing the metal plane, the field lines passing through the coil will be subjected to a conventional device repulsive lines of magnetic force (lines of magnetic force because the coil must be perpendicular to the plane of propagation). 由于在本发明的实施例中,磁力线沿磁芯的平面传播,因此也是沿金属平面传播,使得性能得到提高。 Since the embodiment of the present invention, the magnetic lines of force, and therefore the propagation direction of the metal core along a propagation plane, so that the performance is improved. 一个附加的好处是,本发明的实施例的次级装置内的f兹芯可以作为初级装置产生的电》兹场和》兹芯另一侧上的^f壬4可元件(例如电^各和电池组电池)产生的电》兹场之间的屏蔽。 An additional advantage is that the electric "field and hereby" ^ f nonyl element 4 may be (e.g. hereby electrically on the other side of the core within the secondary f hereby die apparatus embodiment of the present invention may be produced each as a primary means ^ and electrical battery cells) generated hereby shielding between fields. "

•由于本发明的实施例的次级装置的-兹芯的导》兹率高于空气的导磁率,因此它用来聚集磁力线,这样能捕获更多的磁力线, 否则磁力线将流经等价的空气截面。 • Since the secondary embodiment of the apparatus of the present invention - hereby guide core "is hereby higher than the air permeability, it is used to collect magnetic lines of force, so that more magnetic fluxes can capture, or magnetic force lines flowing through the equivalent air-section. 磁芯"形状因子"的大小(等价的磁力线捕获范围)由磁芯的最长的平面尺寸而确定为一阶近似。 Core "form factor" in size (equivalent to the magnetic field lines capture range) is determined by the longest planar dimension of the core is a first order approximation. 所以,如果本发明的实施例的次级装置的-兹芯的平 Therefore, if the secondary device of the embodiment of the present invention - hereby flat core

面尺寸具有较大地非正方形长宽比,例如长宽比为4: 1的矩形,而不是长宽比为1: 1的正方形,它将l姿比例捕获更多的沿平行于最长平面尺寸的方向传播的任何》兹力线。 Dimensions having largely non-square aspect ratio, for example, an aspect ratio of 4: 1 is rectangular, rather than an aspect ratio of 1: 1 is square, it will capture more l ratio pose a direction parallel to the plane of the longest dimension any "hereby force line direction of propagation. 因此,如果》兹芯用于具有受限平面形状比例的i殳备(例如,T者如耳才几或钢笔的长薄设备),与相同区域的传统线圈的性能相比,其性能将大大提高。 Therefore, if "i hereby Shu prepared having a core (e.g., T are only a few such as the ear or long thin pen device) is limited to a planar shape ratio, compared with the same properties of conventional coil region, its performance will be greatly improve.

•次级装置紧邻初级装置。为了4吏这一点成为可^f亍,有可能具有两个线圈,例如一个线圈置于另一个线圈的顶部,或一个线圈编织到另一个线圈中,或者与另一个线圈编织在一起,第二线圈能够在初级装置的有效区域内的任何点处产生基本垂直于第一线圈的方向的净电流。这两个线圈可以交替地被驱动,使得每一个被激活一段时间。另一个可能是相隔四分之一周期驱动两个线圈,从而在平面内产生一个旋转f兹偶极子。这在图9中示出。这一点对于其它组合形式的线圏结构也是可能的。潜抛廖使用并联或串联谐振电路驱动线圈是本领域为人公知的。例如在串联谐振 The secondary coupling means to be effective in certain applications, may require a primary device, it will effectively transfer electrical energy to the bar 4 without a secondary device i gallon secondary device away how the force transfer, conditions are: • secondary conductors the central axis is not perpendicular to the plane, and; • secondary device in close proximity to the primary unit 4 may become official this ^ f right foot, it is possible to have two coils, for example, a coil is placed on top of the other coil, or a coil. woven into another coil, another coil or woven together, the second coil can be in the effective area of ​​the primary means of generating any net current point substantially perpendicular to the first coil. the two coils may be alternately are driven, each of which is activated such that a period of time. another possibility is to drive two coils spaced apart quarter cycle, thereby generating a rotation in a plane f hereby dipole. this is shown in figure 9. this for other combinations of rings of wire structures are also possible. latent throwing Liao using parallel or series resonant circuit for driving the coil is well known in the art man. for example, in a series resonant 路中,线圈和电容器的阻抗在谐振时相等且相反,所以电路的总阻抗最小,且流经初级线圏的电流最大。通常还将次级装置调i皆到工作频率,以〗吏感应电压或电流最大。在一些类似电动牙刷这样的系统中,通常有这样一个电3各,该电路在次级装置不存在时被解谐(detumed),并且当次级装置在适当的位置时进行调谐。次级装置中存在的》兹性材料改变初级装置的自感,并^吏电^各发生谐振。在其它类似无源无线标签(passive radio tag)这样的系统中,次级装置中没有石兹性材料,所以不会影响该系统的谐振频率。这些标签通常4艮小并远离初级装置使用,从而即使有》兹性材#+存在,初级装置的感应也不会显著改变。而在所^是出的系统中,情况并非如此:•高导磁率磁性材料可以存在于次级装置中,并紧邻初级装置使用;• 一个或多个次级装置可以同 Way, the impedance of the coil and the capacitor are equal and opposite at resonance, the minimum total impedance of the circuit, the maximum current flowing through the primary line and the rings of the general i are also transferred to the secondary device operating frequency, the induced voltage to〗 Officials or maximum current. in such a system similar to some of the electric toothbrush, typically 3 each have such a power, the circuit is detuned when no secondary device present (detumed), and when the secondary device is tuned at the appropriate position the secondary device present "hereby change material self-inductance of the primary device and each ^ ^ officials electrically resonate. in such a system, other like passive radio tags (passive radio tag), the secondary device is no stone hereby material, it will not affect the resonant frequency of the system. these tags are typically smaller and Gen 4 away from the primary use of the device, even if the "+ # hereby exemplary material is present, the primary sensing means does not significantly change, while in the ^ is the system, not the case: • high permeability magnetic material may be present in the secondary device and the primary means used immediately; • one or more secondary devices may be the same 紧邻初级装置。 Adjacent to the primary device. 这产生了显著改变初级装置的感应的效果,并才艮据垫纟反上存在的次级装置的数量改变不同的级别。 This change resulted in a significant induction of the primary effect of the device, and only the number of data Gen secondary device present on the pads of varying different levels of anti Si. 当初级装置的感应被改变时,电路在一特定频率产生谐振所要求的电容也随之改变。 When the primary sensor means is changed, a specific frequency generating circuit resonant capacitance required also changed. 使电路保持谐振有三种方法:•借助于控制系统动态改变工作频率;» 4昔助于控制系统动态改变电容,以〗吏在预定频率时发生i皆振;•借助于低Q系统,该系统在电感范围内保持谐振。 The circuit maintaining a resonance three ways: • dynamically change the operating frequency by means of the control system; »4 Xi dynamically varying the capacitance means of the control system, with i〗 Officials occurs at a predetermined frequency are vibration; • by means of a low-Q system a resonant inductor in the holding range. 改变工作频率带来的问题是,次级装置通常^皮构造为在一预定频率发生谐振。 Changing the operating frequency of the problem is caused by the secondary device is generally configured to transdermal ^ to resonate at a predetermined frequency. 如果工作频率改变,次级装置将被失谐。 If the operating frequency is changed, the secondary device is detuned. 为了克服这个问题,可以改变电容而不改变工作频率。 To overcome this problem, you can change the capacitance without changing the operating frequency. 次乡及装置可以净皮i殳计为4吏得每一靠近初级装置方文置的附加设备将4吏电感变为一个量子级别,而将一个适当的电容器接入以使电路在一预定频率发生谐振。 Rural and secondary means may be calculated as net Paper i Shu 4 officials each have additional devices placed close to the primary device will Fang officials inductor 4 becomes a quantum level, and the capacitors into an appropriate frequency to cause a predetermined circuit resonance occurs. 由于这一谐振频率的改变,充电表面上的设备的数量可以被检测到,并且初《及装置也可以感觉到4可时有东西靠近充电表面或远离充电表面。 Since the resonance frequency changes, the number of devices on the charging surface may be detected, and the beginning "and 4 means may be felt near the charging surface or something away from the surface of the charging time. 如果除了一个次级从属设备之外有一个导》兹物体》文置于充电表面附近,则不太可能把系统改变到预定的量子级别。 If in addition there is a secondary slave device other than a guide "hereby object" paper placed near the charging surface, it is unlikely to change the system to a predetermined quantum level. 在这种情况下,系统能自动i也失i皆并减小流入线圈的电流。 In this case, the system can automatically i are also lost and to reduce the current i flowing through the coil. 附图说明为了更好的理解本发明,以及显示它是如何被实施的,现在将仅仅通过举例的方式对附图进行参考,其中:图1示出典型现有技术的无接触电能转移系统的^兹设计,该系统要求初级装置和次级装置的4fr确对准;图2a示出另一典型现有^支术的无4妄触电能转移系统的磁设计, 该系统的初级装置中包4舌一个大线圈;图2b示出在3巨离线圈平面5mm处大线圈内部的非均匀场分布,在中央具有最小量;图3示出一种多线圈系统,其中每一线圈^皮独立驱动^^人而产生局部化的场;图4a示出所才是出的系统的一个实施例,该实施例显示与现有技术的实质性不同,图中不包括次级装置;图4b示出一个带有两个次级装置的所提出的系统的实施例;图4c示出糸^及装置的有-支区i或的4黄截面,以及导线产生的》兹通密度的等势线;图4d示出所提出的发明的该特定实施例 For a better understanding of the invention, and show how it is implemented, will now be only by way of example with reference to the accompanying drawings in which: Figure 1 shows a contactless power transfer system of a typical prior art ^ hereby design, the system requires 4fr primary means and secondary means determines the alignment;
