Wide-range robust wireless power transfer using heterogeneously coupled and flippable neutrals in parity-time symmetry.

ABSTRACT: Recently, stationary wireless power transfer (WPT) has been widely adopted in commercial devices. However, the current WPT configuration is limited in its operational area and susceptible to operating condition changes, impeding its applications for dynamic environments. To overcome the limitations, we propose a WPT system with laterally aligned neutral elements in parity-time (PT) symmetry, which can widen the operational area with the number of neutrals N. Compared to the conventional multiple-input-single-output WPT, the dimension of system complexity is substantially reduced from R × C^N to R^N+1 because the neutral amplitudes are simply controlled by coupling capacitors. The operational frequency is automatically adjusted to a rea
