N2 - Parity-time (PT) symmetry, a concept ranging from quantum field theories and mathematical physics to classical optics, is generalized to a wireless power transfer (WPT) system in [7]. However, the already introduced system is based on an operational amplifier, limiting the power transfer efficiency of the whole system. In this paper, the concept of PT symmetry is generalized to a switch-mode WPT system. PT symmetry is achieved with a nonlinear gain element which is a single-phase bridge inverter, achieving robust wireless power transfer scheme. It is shown in simulation that the system could adjust the frequency within tens of switching period, providing attractive way of dynamic charging. The analysis of the whole system is based on coupled mode theory (CMT).
