    • A contactless power receiver is provided with a dynamically tuned pick up coil. The power transfer capacity of this power receiver is dynamically tuned using semiconductor switches that are operated in linear mode over part of their operation. The semiconductor switches are driven by a controller that is configured to implement a range of control strategies depending on system requirements. The semiconductor switch maybe used by itself or in conjunction with reactive elements to dynamically tune the pick up coil. In some implementations the contactless power receiver maybe configured to work with a consumer electronic or a wireless sensor device. The contactless power receiver can be integrated with the energy storage component of the device to provide a retrofit solution for existing products. The device can then be placed in vicinity of a planar magnetic field generated by a charging pad.
    • 非接触式电力接收器具有动态调谐拾取线圈。 使用在其一部分操作中以线性模式操作的半导体开关来动态地调整该功率接收器的功率传递容量。 半导体开关由控制器驱动,控制器被配置为根据系统要求实现一系列控制策略。 半导体开关本身或与电抗元件结合使用可以动态地调谐拾音线圈。 在一些实施方式中,非接触式电力接收器可以被配置为与消费电子或无线传感器设备一起工作。 非接触式电源接收器可与设备的能量存储部件集成,为现有产品提供改进解决方案。 然后将该装置放置在由充电垫产生的平面磁场附近。
