Abstract
A wireless power system has a wireless power transmitting device and a wireless power receiving device. A clock signal may be provided to inverter circuitry in wireless power transmitting circuitry at a power transmission frequency. The clock signal may cause transistors in the inverter circuitry to turn on and off to create AC current signals through the wireless power transmitting coil. The clock signal may be processed to mitigate electromagnetic interference in the system.
