  • Patent number: 10763698
    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.

  • Patent number: 10700599
    Abstract: A power system includes a power conversion stage that receives power from an input source and delivers power to a load via a power distribution bus. A control system samples the voltage delivered by the power conversion stage at a location close to the output of the power conversion stage and the load voltage at a location close to the load. The control system further measures the current flowing between the output and the load through the power bus. The samples may be used to determine a representation of the bus resistance. The determined bus resistance may be used to introduce a negative resistance characteristic in the power conversion stage as a way of compensating for the actual bus resistance.
