Abstract

The paper investigates the implementation of the phase-controlled Class E asymmetric inverter topology in a near-field wireless power transfer application. The purpose of this design is to achieve high efficiency performance and desired output power through duty cycle and phase shift compensation under coupling and load variations, which is an issue caused by unintentional misalignment of transformer coils. Since the application is near-field, the coupling coefficient k ranging from 0.4 to 0.6 was utilized through simulations, and the appropriate compensation was applied to improve the overall power efficiency of the system.
