| 摘要 | 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. | ||

| 主权项 | 1. A method of powering wirelessly powered devices comprising: providing a wirelessly powered device and a wireless power transmission system; constructing, via the wireless power transmission system, a power optimized waveform, wherein the power waveform comprises: a summation of a plurality of subcarriers having distinct frequency components; anda plurality of cycles, wherein each cycle of the power optimized waveform includes a charge portion and a starve portion, and further wherein the maximum voltage of the charge portion is at least double the Root Mean Square (“RMS”) voltage of the starve portion; transmitting, from the wireless power transmission system, the power optimized waveform; and receiving, at the wirelessly powered device, the power optimized waveform. | ||
