Abstract
This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for wireless power transmission. A wireless power transmission apparatus (such as a charging pad) may provide multiple wireless power signals to a wireless power receiving apparatus. 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 wireless energy 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.
