具体实施方式
下文中，将参照附图更详细地描述示例性实施例。
在下面的描述中，当在不同的附图中描述相同的元件时，将相同的标号用于相同的元件。为了有助于对示例性实施例的充分的理解，提供了在说明中限定的主题，诸如详细的构造和元件。因此，明显的是，可以在没有明确限定的主题的情况下实施示例性实施例。此外，没有详细地描述在现有技术中已知的功能或元件，因为具有不必要的细节的它们可能使示例性实施例变得模糊。
图1是示出根据示例性实施例的无线功率传输系统的视图。根据示例性实施例的无线功率传输系统10包括功率传输设备100、第一功率接收设备200和第二功率接收设备300。
功率传输设备100使用传输谐振器(将在下面参照图2A和图2B进行详细描述)将磁能传输到第一无线功率接收设备200和第二无线功率接收设备300。
更具体地讲，功率传输设备100使用以圆柱形形状形成的传输谐振器来产生相对于地面的水平方向的磁场和垂直方向的磁场。功率传输设备100使用水平方向的磁场对放置在功率传输设备100的支撑件140上的第一功率接收设备200充电，并使用垂直方向的磁场对放置在功率传输设备100的主体130的顶表面170上的第二功率接收设备300充电。
具体地讲，圆柱形的主体130包括传输谐振器，该传输谐振器包括圆柱形的传输导电线圈(wire loop)，以同时产生水平方向的磁场和垂直方向的磁场。
第一功率接收设备200使用接收谐振器(将在下面参照图2A和图2C进行详细描述)利用从功率传输设备100传输的磁能充电。更具体地讲，第一功率接收设备200使用由功率传输设备100的传输谐振器产生的水平方向的磁场充电。第一功率传输设备200的接收谐振器包括第一接收导电线圈，其中，线圈面与水平方向的磁场垂直。这里，线圈面是由接收导电线圈形成的面。
第一功率接收设备200可以为3D眼镜，但是不限于此。例如，第一功率接收设备200可以为遥控器或移动电话。如果将遥控器或移动电话放置在支撑件140上，则因将遥控器或移动电话的接收导电线圈的线圈面放置为与水平方向的磁场垂直而对遥控器或移动电话进行充电。
第二功率接收设备300使用接收谐振器利用从功率传输设备100传输的磁能充电。更具体地讲，第二功率接收设备300使用由功率传输设备100的传输谐振器产生的垂直方向的磁场充电。第二功率接收设备300的接收谐振器包括第二接收导电线圈，其中，线圈面与垂直方向的磁场垂直。
第二功率接收设备300可以为遥控器或移动电话，但是不限于此。例如，第二功率接收设备300可以为3D眼镜。如果将3D眼镜放置在主体的顶表面上，则因将3D眼镜的接收导电线圈的线圈面放置为与垂直方向的磁场垂直而对3D眼镜进行充电。
功率传输设备100、第一功率接收设备200和第二功率接收设备300可以具有高的谐振Q因数(Q-factor)。这是因为能量接收效率随着功率传输设备100以及功率接收设备200和300的Q因数的增加而增加。具体地讲，无线功率传输系统10可以具有与(Qs×Qd)的平方根成比例的传输效率，其中，Qs是功率传输设备的Q值，Qd是功率接收设备的Q值。此外，功率传输设备100以及功率接收设备200和300可以包括环式谐振器(loop typeresonator)，以具有高的Q因数，并可以被构造为高质量低损失电容器(即，具有低电阻引线的电容器)，以具有高的Q因数。此外，因为当功率传输设备100以及功率接收设备200和300处于金属材料附近时，Q值突降，所以功率传输设备100以及功率接收设备200和300可以包括屏蔽结构。
下文中，将参照图2A、图2B和图2C来说明无线功率传输系统10的无线式充电的方法。
如上所述，无线功率传输系统10包括功率传输设备100和第一功率接收设备200。功率传输设备100包括射频(RF)放大器单元110和传输谐振器单元120。
RF放大器单元110使用从电源单元(未示出)传输的DC电压来产生高频率的交流(AC)波形，并产生集中在一定谐振频率上的磁场。此外，RF放大器单元110产生高频(MHz级别)的AC波形，并向传输谐振器单元120激励该AC波形。此时，RF放大器单元110具有可变的特定工作频率。
RF放大器单元110的特定工作频率与在传输谐振器单元120处产生的磁场的谐振频率相同，RF放大器单元110的工作频率可以为例如13.65MHz。然而，这仅仅是一个示例，且RF放大器单元110的工作频率可以在从1MHz至30MHz的范围内。如果功率传输设备100具有1～30MHz的工作频率，则功率传输设备100可以具有小的谐振器和高的Q因数，如果功率传输设备100不具有1～30MHz的工作频率，则传输效率因功率元件的限制而突降，因此，功率传输设备100效率不高。
如图2B中所示，传输谐振器单元120产生将被传输到第一功率接收设备200的磁能。更具体地讲，传输谐振器单元120包括馈电导电线圈126、传输导电线圈125和谐振电容器127。
馈电导电线圈126在以感性耦合的形式连接的传输导电线圈125中感生出电流，并引发集中在一定谐振频率上的磁场的产生。此时，谐振频率可以为如上所述的13.65MHz。然而，这仅仅是一个示例，RF放大器单元110的工作频率可以在从1MHz至30MHz的范围内。
传输导电线圈125产生集中在一定谐振频率上的磁场。此时，传输导电线圈125可以形成为圆柱形形状，以产生与地面平行的磁场和与地面垂直的磁场。具体地讲，可以通过圆形地弯曲来形成传输导电线圈。传输导电线圈125可以形成为与主体130的内边缘或表面接触。将在下面参照图4A至图4C对由传输导电线圈125产生的磁场进行说明。
传输谐振器单元120是LC谐振器，并通过改变谐振电容器和电感器的值来改变谐振频率。
功率传输设备100可以包括屏蔽构件，以防止在功率传输设备100处于金属材料附近的情况下Q因数突降的涡流场现象(Eddy field phenomenon)。将在下面参照图5对功率传输设备100的屏蔽构件进行说明。
如上所述，功率传输设备100将由传输谐振器单元产生的磁能无线式地传输到功率接收设备200和300。
此外，功率接收设备200包括接收谐振器单元210、整流器单元220、DC/DC转换器单元230和充电单元240，如图2A中所示。
接收谐振器单元210接收集中在特定频率上的磁能。更具体地讲，如图2C中所示，接收谐振器单元210包括：接收导电线圈215，形成在功率接收设备200(例如，3D眼镜)的边缘上；谐振电容器216，连接到接收导电线圈；拾取导电线圈217。例如，如果功率接收设备200是3D眼镜，则接收导电线圈215可以形成在3D眼镜的镜框中，如果功率接收设备200是遥控器或移动电话，则接收导电线圈215可以形成在遥控器或移动电话的边缘中。然而，这仅仅是一个示例，接收导电线圈215可以形成在3D眼镜、遥控器和移动电话的不同位置中。可以使用印刷电路板(PCB)或薄膜PCB来形成接收导电线圈215。
由传输谐振器单元120产生的一定谐振频率的磁场激励接收谐振器单元210，从而电流在接收导电线圈215中流动。此时，接收导电线圈215因被放置为与传输谐振器单元120产生的水平方向的磁场垂直或与垂直方向的磁场垂直而被激励。更具体地讲，如果功率接收设备200放置在支撑件140上，则接收导电线圈215因被放置为与传输谐振器单元120产生的水平方向的磁场垂直而被激励。此外，如果功率接收设备200放置在主体130的顶表面170上，则接收导电线圈215因被放置为与传输谐振器单元120产生的垂直方向的磁场垂直而被激励。
拾取导电线圈217使得在接收导电线圈215中产生电流，并将电流提供到整流器单元220。
整流器单元220将从拾取导电线圈传输的AC电压整流为DC电压。如在现有技术中已知的，整流器单元220可以包括桥式二极管和用作滤波器的电容器，桥式二极管包括四个二极管。然而，这仅仅是一个示例，整流器单元220可以使用将AC输入整流为DC输出的不同的电路来实现。
因为经整流器单元220整流得到的DC电压不保持恒定的电压，所以DC/DC转换器单元230将DC电压调节成恒定的。
充电单元240以经整流的恒定电压对电池进行充电。具体地讲，充电单元240可以包括充电集成电路(IC)和电池，以控制使用整流器单元220的输出电压的充电操作。
下文中，将参照图3和图4对功率传输设备100进行详细描述。
图3是示出根据示例性实施例的功率传输设备100的外部构造的视图。如图3中所示，功率传输设备100包括主体130、支撑件140、显示单元150和电源按钮单元160。
主体130容纳功率传输设备100的传输谐振器单元120。具体地讲，如图3中所示，主体单元130可以形成为圆柱形形状，以容纳圆柱形的传输谐振器单元120。主体130包括平坦的顶表面170，第二功率接收设备300放置在平坦的顶表面170上。因此，第二功率接收设备300放置在主体130的顶表面上，从而可以通过垂直方向的磁场对第二功率接收设备300进行无线式地充电。
支撑件140形成在主体130的侧表面上。如图3中所示，支撑件140的边缘包括显示单元150，以告知功率传输设备100的电源开/关状态。支撑件140可以具有盘形形状，以容纳第一功率接收设备200。因此，第一功率接收设备200放置在支撑件140上，从而可以通过水平方向的磁场对第一功率接收设备200进行无线式地充电。
此外，功率传输设备100包括电源按钮单元160，以根据是否对功率接收设备200和/或300进行充电来控制供电。
图4A至图4C是示出根据示例性实施例的由功率传输设备100产生的磁场的视图。
如图4A中所示，圆柱形的功率传输设备100产生垂直方向的磁场430和水平方向的磁场440。因此，垂直方向的磁场430与第二功率接收设备300的接收导电线圈的线圈面410垂直，从而对第二功率接收设备300进行充电。此外，水平方向的磁场440与第一功率接收设备200的接收导电线圈的线圈面420垂直，从而对第一功率接收设备200进行充电。
图4B是示出包括在图4A中示出的功率传输设备100中的传输谐振器单元120的视图。如上所述，传输谐振器单元120包括以圆柱形形状形成的传输导电线圈125，以使功率传输设备100产生垂直方向的磁场430和水平方向的磁场440。
图4C是示出圆柱形的传输谐振器单元120的磁场。如图4C中所示，圆柱形的传输谐振器单元120的磁场沿与顶表面和侧表面垂直的方向形成。
如果功率传输设备100放置在金属板(metal table)上，则因金属板导致出现传输谐振器单元120的谐振频率改变或Q因数降低的涡流效应。因此，功率传输设备100可以包括屏蔽结构，以防止功率传输设备100的充电性能因金属板而劣化的现象。下文中，将参照图5来说明功率传输设备100的屏蔽结构。
图5是示出根据示例性实施例的包括屏蔽结构的功率传输设备100的示图。在图5中示出的RF放大器单元110和传输谐振器单元120与上面参照图2描述的RF放大器单元110和传输谐振器单元120相同。
屏蔽壳113围绕功率传输设备100的RF放大器单元110，从而防止涡流效应。可以通过镀锡来形成屏蔽壳113。
功率传输设备100可以进一步包括在RF放大器单元110和传输谐振器单元120之间的屏蔽构件115。可以通过铁氧体片来实现屏蔽构件115。屏蔽构件115确保了低阻抗路径，从而补偿大部分的Q因数。
此外，可以在RF放大器单元110和传输谐振器单元120之间设置预定的间隙117，从而防止谐振频率预先改变。
通过屏蔽壳113、屏蔽构件115和间隙117防止了Q因数减小和谐振频率改变的涡流现象。
在上面的实施例中，接收导电线圈与在传输谐振器单元120处产生的磁场垂直。然而，这仅仅是一个示例，且可以以不同的角度放置接收导电线圈。即，与磁场垂直的接收导电线圈仅意味着能量接收效率最高。可以以不同的角度(接近于直角)来实现本发明的构思。
如上所述，通过单个功率传输设备对多个功率接收设备(3D眼镜、遥控器和移动电话)进行充电，因此，用户可以更容易且更有效率地对各种设备进行充电。
前述示例性实施例和优点仅是示例性的，且不应被解释为限制本发明的构思。可以容易地将示例性实施例应用于其他类型的设备。此外，示例性实施例的描述意在举例说明，且不意在限制权利要求的范围，且许多替换、修改和变化对于本领域技术人员来说将是明显的。
