摘要： This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for wireless power transmission. A wireless power receiving apparatus may be configured to combine power from multiple wireless power signals. In some implementations, the wireless power receiving apparatus may combine wireless power received from multiple secondary coils to provide a combined wireless power signal to a load, such as a battery charger or electronic device. In some implementations, each set of primary coil and secondary coil may utilize low power wireless power signals (such as 15 Watts or less) in accordance with a wireless charging standard. By combining power from multiple low power wireless power signals, the wireless power receiving apparatus may support higher power requirements of an electronic device. The disclosed designs may minimize electromagnetic interference (EMI) and provide greater efficiency of wireless power transfer.

摘要： This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for a wireless power transmission apparatus that supports charging of one or more wireless power receiving apparatuses. The wireless power transmission apparatus (such as a charging pad or surface) may include multiple primary coils and multiple local controllers (such as one local controller per primary coil). Each local controller can independently activate a primary coil to supply power to a wireless power receiving apparatus. Thus, the wireless power transmission apparatus may support concurrent charging of multiple wireless power receiving apparatuses. When a first primary coil is activated, a local controller can mute or disable the adjacent primary coils (near the first primary coil) to mitigate undesirable interference. In some implementations, the local controller may provide a status to other local controllers (associated with adjacent primary coils) to disable the adjacent primary coils.
