Abstract:
A current-based resonant power delivery (CRPD) device and method with multi-cycle switching that enables efficient inductive power transmission at large distances. The proposed CRPD switches the Rx LC-tank for several cycles to utilize it as a current source. Therefore, the voltage across the load (RL) can be significantly higher than the Rx LC-tank voltage. In CRPD, the energy may first be stored in the receiver (Rx) coil by shorting the Rx LC-tank for several power carrier cycles. At the peak of Rx coil current, the coil energy may then be transferred to load (RL) for a quarter of the power carrier cycle.
