Abstract
A method, system and an apparatus of resonant induction to power a graphics processing unit (GPU) are disclosed. In one embodiment, a resonant induction system is described. The resonant induction system includes a transmitter circuit tuned to a resonant frequency. The transmitter circuit generates a non-radiative magnetic field when a control current is passed through the transmitter circuit. The resonant induction system also includes a receiver circuit, resonantly coupled to the non-radiative magnetic field generated by the transmitter circuit, and tuned to the resonant frequency of the transmitter circuit. The receiver circuit is located in a GPU. The transmitter circuit and the receiver circuit are resonantly coupled to each other at the resonant frequency. A control current source supplies the control current to the transmitter circuit. A feedback module may be communicatively coupled to the GPU to determine a power requirement of a particular computer graphics application.
