Abstract: A system for providing electrical power to a remote device through wireless transmission is provided. The system includes a power transmitting data unit (PTDU), at least one power receiving data unit (PRDU) and at least one power throttling circuit. The PTDU receives electrical power from a power source. The PRDU is connected to a load device. The PRDU includes a resonator and a power conversion circuit. The resonator receives electromagnetic waves from the PTDU and converts the electromagnetic waves into the electrical power. The power conversion circuit provides target power to the load device. The power throttling circuit determines how much electrical power from the resonator needs to be transmitted to the power conversion circuit based on the power requirement of the load device, wherein the electrical power required for the load device is regarded as the target power.
