Stability of Dynamic Wireless Power Transfer System without Feedback Control against Coil Misalignment
In this paper, we present a design methodology for determining the resonant tank frequency in a feedback control-free dynamic wireless power transfer (DWPT) system for an automatic guided vehicle (AGV). High stability in power transmission characteristics against misalignment between the power transmitting and receiving coils can be achieved by setting a coupling coefficient-independent frequency as the optimum one. The principle of resonant tank frequency determination is originally proposed on the basis of steady-state analysis. The practical effectiveness is verified using a 1.5kW-85kHz DWPT prototype.
