LCC Compensation of Signal Channel for Simultaneous Wireless Power and Data Transfer Systems

Simultaneous wireless power and data transfer (SWPDT) is promising to offer the high-quality communication in various wireless charging scenarios. The high-frequency data carrier-based SWPDT (HFDC-SWPDT) is able to maintain the original power transfer characteristics by only sharing the inductive coupler. Based on HFDC-SWPDT, this paper develops a high-order LCC compensation for the signal channel, which can reduce the interference from the power channel and decrease the required injection current for data transfer. Though the comparison with existing low-order compensations, both the simulation and experiment are used to justify the improved performance of the proposed solution.
