Abstract
In this paper, we present a simple method to extend the feasible rated charging zone of a four-coil coupled wireless charging system (WCS) by optimizing the compensate capacitors of the coils. With the proposed optimizing method, the tolerant lateral misalignment of our WCS prototype has been extended to 44.3% of the coil size, achieving a 38.3% relative improvement.
