摘要： A multi-mode multi-coupling multi-protocol wireless power transmitter (WPT) and its embodiments transmit power to a wireless power receiver (WPR) in a power transfer mode (PTM) and a wireless power protocol (WPP) of the WPR. A first circuit of the WPT includes inductors or capacitors emanating power via a magnetic field or electric field PTM respectively. The WPT sequentially parses a test condition to identify a PTM, a power coupling linkage (PCL) between the WPT and the WPR, and a WPP of the WPR. The WPT identifies a match if the PTM of the first circuit and the WPP of the switch network, the variable matching circuit, a modulator/demodulator block or an out-of-band communication block, and a control logic circuit of the WPT match the PTM and the WPP of the WPR to transmit power to the WPR based on the match.

摘要： A method and system for self-regulating wireless power transmitted to a wireless power receiver (WPR) is provided. An auto-tuning network is operably coupled within the WPR. The auto-tuning network comprises an impedance network that dynamically increases, decreases, or maintains amount of the received wirelessly transmitted power by detecting changes in a rectifier load disposed in the WPR and/or in an output voltage of the rectifier in the WPR. The auto-tuning network self-regulates the wireless power received from a wireless power transmitter (WPT) obviating the need for conventional communication messages. The WPT is hence free from a modulator/demodulator block and an out-of-band communication block and can operate over a limited operating range to enable simpler design for passing EMC regulation. Additionally, the WPR implements a receiver-maximum power-signature algorithm for enabling the WPT to detect unsupported receivers, configure its operating point and range, and terminate power transmission when not needed by WPR.
摘要翻译： 提供了一种用于自动调节发送到无线电力接收器（WPR）的无线电力的方法和系统。 自动调谐网络在WPR内可操作耦合。 自动调谐网络包括阻抗网络，其通过检测设置在WPR中的整流器负载和/或在WPR中的整流器的输出电压中的变化来动态地增加，减少或维持所接收的无线发射功率的量。 自动调谐网络自动调节从无线电力发射机（WPT）接收的无线功率，从而避免了对常规通信消息的需要。 因此，WPT无需调制器/解调器块和带外通信块，并且可以在有限的工作范围内工作，以实现更简单的设计，从而实现EMC调节。 另外，WPR实现了接收机最大功率签名算法，用于使WPT能够检测不受支持的接收机，配置其工作点和范围，并在WPR不需要时终止电力传输。

摘要： A wireless power system (WPS) has a wireless power transmitter (WPT) that appraises an input power available to a power inverter from one or more input power sources. The WPT comprises the power inverter that wirelessly transmits power to a wireless power receiver (WCR) of the WPS, and a power appraiser circuit (PAC). The PAC ascertains maximum input power available to the power inverter from the input power sources. The PAC includes a variable load connected to a path carrying the input power to the power inverter or one or more input pins that receive power ratings of the input power sources that indicate available maximum input power from the input power sources. The ascertaining of maximum input power available to the power inverter from the input power sources appraises the input power available to the power inverter. The WCR receives information representing maximum power deliverable by the WPT.

摘要： A wireless power charger (WPC) integrated into a charging pad (CP) includes a wireless power transmitter (WPT), a location sense mechanism (LSM), a transport mechanism (TM) and a Central Control Unit (CCU). The LSM discovers and conveys the position of a portable device to the CCU when the device is placed on the CP to have its battery wirelessly charged. The LSM uses RF signaling and other capabilities in wireless connectivity standards to detect location of device. With information from the LSM, the CCU, via the TM, moves the WPTM in close proximity to the device. Once at the device position, the WPTM senses the location of the receiver coil in the device, adjusts its position via the TM to gain strong alignment and provides power wirelessly. When charging is complete or if the device is removed from the charging pad, the WPTM returns to its home-base location.

摘要： A wireless power transmitter (WPT) including a first, second, third circuit and a transmit coil for wirelessly delivering power to a wireless power receiver (WPR) including a receiver coil, rectifier, impedance network, protection circuitry, control logic, modulator/demodulator and ADC is provided. A method that enables WPT and WPR to deliver the required power to the WPR's downstream load in planar, orthogonal and intermediate modes of WPR placement on WPT is provided. The WPR is integrated into the strap/frame or in the vital area of the device. To avoid a heated metal object safety issue, the WPT implements a metal object detect algorithm to detect metal objects and terminate transmission of power. To protect their circuitry from induced voltage spikes in excess of acceptable levels, the WPR includes a simple protection circuitry that naturally turns on and siphons out the excess power when the acceptable threshold levels are exceeded.
