Abstract
The present invention describes systems and methods for providing a power optimized waveform. An exemplary embodiment of the present invention provides a method of powering wirelessly powered devices including the step of providing a wirelessly powered device and a wireless power transmission system. Furthermore, the method involves receiving a power waveform to the wirelessly powered device from the wireless power transmission system, wherein each cycle of the power waveform includes a charge portion and a starve portion. Additionally, the maximum voltage of the charge portion is at least double the Root Mean Square (“RMS”) voltage of the starve portion.
