Description

使用可独立调谐的谐振器的无线功率传输
背景技术
本发明涉及无线功率传输，并且具体地，本发明涉及能够适用于对电池等进行充电的技术。
无线功率传输已经有100多年的历史了。随着过去十年中便携式电子设备的迅猛发展，对用于电池充电的无线功率传输的关注也在快速增加。
发明内容
为了增加无线功率传输系统的操作范围，可使用高Q因子的系统，所述系统使用自调谐线圈。自调谐线圈的问题是难以将所述两个线圈调谐至射频源频率并且介于彼此之间(这是通过改变匝数和这些匝之间的距离来进行的，并且不适用于自动反馈控制)。
对于实际的应用诸如用于对家用电器应用进行充电，典型的短程感应充电器只限于若干厘米或甚至若干毫米。高Q因子谐振系统部分地补偿相对于发射器(发射器)和接收器(接收器)之间距离的快速衰减的所接收的功率，以谐振线圈上的高操作电压为代价，因为当接收器装置被移动得更靠近发射器时，接收器线圈电压将上升。高Q系统必须整流和调控数量级为几百伏甚至几千伏的电压。这可能使在该类型的环境中操作的典型的以低电压操作的电子设备产生问题。高输入电压调节器是存在的，但它们效率不高、体积庞大且造价昂贵。
感应式充电器例如电池充电器通常在短程空间范围内操作，通常只限于若干厘米或甚至若干毫米。高Q谐振系统部分地补偿相对于发射器(发射器)和接收器(接收器)之间距离的快速衰减的所接收的功率。虽然更好的Q因子能够在兆赫兹范围内，例如在5至27MHz范围内产生，但在这一范围内，典型的整流器电路的性能受到半导体装置的最大操作频率的限制。在这些高操作频率下，常规整流器设计可能不能够表现得令人满意。在这种高频率下，常规整流器的输出电压波形可包括因寄生电感和电容谐振而产生的鸣振瞬态。这些瞬态导致整流效率损耗和输出信号噪声。此外，整流器的输入阻抗特性还随频率和负载而改变。为了减小该影响，使用系列谐振转换器通过改变切换频率来进行调控并抵消反应性阻抗变化。
根据一个方面，一种电路包括用于无线接收能量的谐振器电路，所述谐振器电路包括具有较大数目的匝数N1的接收器线圈和横跨接收器线圈与接收器线圈分路连接的可变电容装置，并且可变电容器和接收器线圈的本征电容形成谐振器电路；和输出线圈，所述输出线圈与接收器线圈的匝数N1相比具有较低数目的匝数N2，输出线圈感应耦合到接收器线圈以从该电路提供功率输出，其中谐振器电路具有约100kHz至30MHz范围内的谐振频率。
以下为实施例。
谐振器电路由可变电容装置调谐至100kHz至30MHz范围内的谐振频率。谐振器电路以高电压振荡并产生耦合到次级线圈的强磁场。所述两个线圈的电感耦合在输出线圈处产生与VL(线圈)＝Vin*Q*N2/N1相关的输出电压。该电路还包括用于将输出线圈上的AC电压转换为DC电压的电路系统。该电路还包括用于将输出线圈上的AC电压转换为DC电压的电路系统，该电路系统包括横跨次级线圈分路连接的电容器和耦合到该电容器的DC/DC转换器或电池充电器。该电路还包括连接至输出线圈以将输出线圈上的AC电压转换为DC电压的整流器电路，该电路系统还包括横跨次级线圈分路连接的电容器和与电容器串联耦合的DC/DC转换器。
根据另一个方面，一种电路包括用于无线传输能量的谐振器电路，该电路包括具有较大数目的匝数N1的发射器线圈；横跨发射器线圈与发射器线圈分路连接的可变电容装置，并且可变电容器和发射器线圈的本征电容形成谐振器电路；和被构造成耦合到输入射频源的输入线圈，其中输入线圈与发射器线圈的匝数N1相比具有较低数目的匝数N2，并且输入线圈感应耦合到发射器线圈以从该电路提供功率输出，其中谐振器电路具有约100kHz至30MHz范围内的谐振频率。
以下为实施例。
谐振器电路由可变电容装置调谐。谐振器电路以高电压振荡并在发射器线圈处产生强磁场。该电路还包括连接至输入线圈的射频源。发射器和输入线圈的电感耦合在发射器线圈处产生与VL(线圈)＝Vin*Q*N1/N2相关的输出电压，其中Vin与连接至输入线圈的射频源的电压相关。
根据另一个方面，一种用于无线能量传递的系统包括用于无线传输能量的电路，该电路包括第一谐振器电路，所述第一谐振器电路包括具有较大数目的匝数N1的发射器线圈；横跨发射器线圈与发射器线圈分路连接的可变电容装置，并且可变电容器和发射器线圈的本征电容形成谐振器电路；被构造成连接至输入射频源的输入线圈，其中输入线圈与发射器线圈的匝数N1相比具有较低数目的匝数N2，并且输入线圈感应耦合到发射器线圈以按约100kHz至30MHz范围内的谐振频率从该谐振器电路提供功率输出。一种用于无线接收能量的电路，该电路包括第二谐振器电路，所述第二谐振器电路包括感应耦合到发射器线圈的接收器线圈(接收器线圈具有较大数目的匝数N3)；横跨接收器线圈与接收器线圈分路连接的可变电容装置，并且可变电容器和接收器线圈的本征电容形成第二谐振器电路；输出线圈，所述输出线圈与接收器线圈的匝数N1相比具有较低数目的匝数N2，输出线圈感应耦合到接收器线圈以从该电路提供功率输出，其中谐振器电路具有约100kHz至30MHz范围内的谐振频率。

具体实施方式
现在参见图1，示出了一种包括发射器11和接收器21的无线能量传递布置方式10。发射器11和接收器21包括分别用于传输和接收无线功率的相应的可调谐的谐振器12,22。这些可调谐的谐振器12,22是与发射器侧11上的驱动器电子装置16和接收器电子装置26例如接收器侧21上的整流器电路32和降压DC/DC 34转换器电隔离的。
可调谐的发射器谐振器12包括具有较高数目的匝数N2的线圈15(发射器线圈)和具有相对较低数目的匝数N1的线圈14(输入线圈)，其中N2比N1大大约10至1000倍。可调谐的发射器谐振器12也包括横跨线圈15分路耦合的可变电容元件(可变电容器)18。可变电容元件18允许经由电隔离的LC电路(线圈15和电容器18)来调谐谐振器12。线圈15与具有匝数N1的线圈14相比具有相对较大数目的匝数N2。可调谐的发射器谐振器12经由输入线圈14被馈送。从射频源16向输入线圈14馈送射频信号。
典型的带宽范围、电压范围和功率范围为：
频率范围：100kHz至30MHz；
电压范围：5V至48V；
功率范围：1mW至100W
其它范围和上述范围内的子范围诸如5MHz至27MHz也是可能的。
匝数比率N2/N1允许输入线圈14处的相对低电压通过感应耦合向发射器线圈15传输电能并在发射器线圈15处产生非常高的磁场。该高磁场感应耦合到接收器谐振器22，如下文即将讨论的那样。可调谐的发射器12因此具有在高电压下操作的谐振结构，从而产生强磁场。
通过使用带有空气间隙可变电容器和可变调谐的空气芯线圈来提供谐振器。其它构型也是可能的，这取决于所期望的特性，包括对可调谐的发射器谐振器12的带宽要求、电压要求和功率要求。可调谐的接收器谐振器22包括具有较高数目的匝数N2的线圈25(接收器线圈)和具有相对较低数目的匝数N1的线圈24(输出线圈)，其中N2比N1大大约10至1000倍。可调谐的接收器谐振器22也包括横跨线圈25分路耦合的可变电容元件(可变电容器)28。可变电容元件28允许经由电隔离的LC电路(线圈25和电容器28)来调谐谐振器22。与具有匝数N1的线圈24相比具有相对较大数目的匝数N2的线圈25允许接收器谐振器(线圈26和电容器28)有效地经由对线圈25的电感耦合耦合到由发射器谐振器12产生的相对高磁场中，从而在线圈25处产生相对高电压。线圈25感应耦合到线圈24。
在一些实施例中，线圈24与线圈15磁屏蔽，以便不允许在发射器中的线圈15和接收器中的线圈24之间产生显著的电感耦合。此类磁屏蔽可通过各种方式来实现，包括将次级线圈放置在由接收器21上的初级线圈25所限定和约束的区域内。一种用于磁屏蔽接收器中的线圈24的此类布置方式示出于图2中。
现在参见图2，示出了结构40，其承载了可用作可调谐的谐振器12,22(图1)的一部分的两个线圈。结构40包括具有第一线圈(图1中例证性的25)的带42或盘，所述第一线圈由在带42的外表面42a上设置的连续的电隔离的导体44的N2匝构成。结构40也包括第二线圈(图1中例证性的24)，其由在带42的内表面42b上设置的连续的电隔离的导体46的N1匝(其中N2>>N1)构成。该结构40允许例如具有设置在带42的外表面42a上的第一线圈25的可调谐的谐振器22(图1)至少部分地将第二线圈24与由其它线圈产生的可能耦合到结构40的场屏蔽开，诸如将线圈15与可调谐的谐振器12(图1)屏蔽开，同时允许这种场耦合到结构40的线圈25。
可调谐的接收器谐振器22经由电感耦合从可调谐的发射器谐振器12接收能量，并且可调谐的接收器谐振器22将所述能量感应耦合到线圈24。在线圈处产生与比率N1/N2成比例的输出电压。该电压远远低于横跨线圈25从可调谐的谐振器12感生的电压。线圈24处的这种较低AC电压由全波整流器33整流以产生DC电压。电容器30整平/过滤该DC电压，并且DC/DC转换器32根据对后续装置诸如负载34的输入电压要求将该DC电压转换为所期望的值。当负载34从DC/DC转换器电路32获得电流时，线圈25的输出端处的电压不下降，而是使得该DC/DC转换器增加流过线圈25的电流。与依赖本征线圈电容的自谐振器线圈相比，用于传输和接收的可独立调谐的谐振器增加了该布置方式的操作范围，并且改善了该布置方式的可制造性。将可变电容器包括在内允许精密地调谐并因此选择谐振器的谐振频率。将分别用于传输和接收的次级线圈14,24包括在内，降低了射频源16处的电压要求、以及对处理电路例如电容器30、整流器33和接收器处的DC/DC转换器32的电压要求。
由于功率输出连接至具有较低数目的匝数N2的线圈24，因此输出电压和谐振器电压之间的比率由所述两个线圈的匝数比率控制，如：
VL(线圈)＝Vin*Q*N2/N1
其中Q为谐振器的品质因子，并且N2和N1分别为线圈25和24的匝数。例如，如果Q＝10，N1＝100且N2＝10，则线圈电压将与输入电压相同，便于整流和调控。该布置方式的另一个优点是能够将发射器和接收器谐振器12,22独立地调谐至振荡器/驱动器射频功率源频率，而不是将所述源调谐至谐振器。这能够允许独立地调谐多个接收器，同时由单一发射器提供功率。可用可变电容器手动地进行调谐，或可使用电压控制的电容器诸如反向偏置的半导体结自动地进行调谐。
在一个例子中，将可550kHz至1600kHz范围内使用的可调谐的AM无线电天线谐振器用于图1的线圈布置方式。发射器线圈由射频振荡器供电，所述射频振荡器经由10W的功率放大器驱动器设定在1MHz正弦信号。接收器线圈能够被移开例如24”。所述两个谐振器被调谐至振荡器频率并且各自的特征在于Q因子为10。
现在参见图3，一种可供选择的增强形式使用了包括线圈64和可变电容器68的可调谐的无源谐振器62，其中谐振器62设置在图1的发射器11和接收器21’(类似于图1的接收器21)之间而无整流器电路。此处，可调谐的无源谐振器62通过围绕谐振频率调谐无源谐振器62并且提供相位控制来提升所接收的功率和范围，从而偏置接收器11’侧上的波形以将射频信号有效地整流耦合到接收器11’。可调谐的无源谐振器62使得谐振无线功率传输系统能够在高射频范围内操作并且提供AC至DC功率转换而无需整流器电路。该技术适用于使用用于传输、调节和接收无线功率的谐振电路来进行交流电至直流电的转换、以及射频至DC(射频至直流电)的转换。
谐振器62为一种谐振频率为f的、由矩形脉冲振荡器和功率开关或放大器驱动的LC振荡电路。无源LC重发器被调谐至谐振频率f的第一谐波2f。所述两个频率在接收器中混合以在输出端产生基本上非对称的DC分量而无需整流器电路。DC功率通过如下方式从AC源产生：混合所述两个信号f和2f以产生具有总的输出电压连同DC分量的信号。所述两个具有不同频率的电压能够通过使用基本频率f和第一谐波2f从相同的AC或射频功率源产生。
通过控制所述两个电压之间的相移，能够在输出端产生更高振幅的正DC分量或负DC分量。所述处于两个频率的信号在功率源处混合或独立地发射并在接收器处混合。通过使用用于发射器和接收器的谐振电路，能够实现输出电压的放大。即，通过混合所述两个正弦波形f和2f(如图4A,4B所示)，产生了具有DC分量的非对称波形。例如，混合具有相等振幅的频率f与第一谐波2f能够产生具有正(图4A)或负(图4B)高振幅半波的总波形，这取决于所述两个电压之间的相移。例如，在图4A中，所述两个源电压之间的270°相移导致正峰69a；而在图4B中，所述两个源电压之间的90°相移导致负峰69b。正峰或负峰69a,69b的优势均可用来直接对电池进行充电而不使用传统的整流器和过滤电路系统。
现在参见图5，在实际的应用中，单线发射器导体70形成设置在某个结构诸如桌子72周边周围的回路，如图所示。发射器电感器70(对应于图1中的线圈15)在所述导体的两端部与调谐电容器74(对应于图1中的电容器18)并联耦合。接收器能够定位在由导体72所包围的区域内，并且高于或低于桌子72的表面约1m。这种单线回路经由如上所述的射频源(未示出)被馈送，并且可在相对大面积内传送功率，从而提供足够的功率以便对低速率间歇使用的装置78诸如家用护理器具例如移动电话、电动剃刀、电动牙刷等或其它具有低平均充电速率的器具进行充电。
该布置方式允许进行能够对多个装置进行充电的射频传输(并且所述发射能够处在可接收的限值内，诸如由例如International Commission onNon-Ionizing Radiation Protection所确立的那些)。利用该布置方式，多个装置可在若干立方米的空间中各自接收例如约100mW(通常需要30mW)，并且谐振重发器提高了用于小装置的功率。在该布置方式中，围绕桌子的回路提供了大的表面积，具有可调谐的接收器谐振器(22或22’)的装置能够自由地定位在其中。
已描述了本发明的许多实施例。然而，应当理解在不背离本发明的精神和保护范围的情况下可作出许多修改。例如，替代无源谐振器，可使用在基本发射器频率的第一谐波或更高谐波下操作的磁场发射器以提供如上所述的有效整流。因此，其它实施例在以下权利要求书的范围之内。
