Abstract

This paper presents the design guidance of a wireless power modulator (WPM) for wireless power transfer (WPT) systems with multiple receivers. The WPM is implemented by an inductive-dominant relay resonator to alter the transimpedances among the receivers through the processes of enhancing, decoupling or weakening the magnetic flux in the receivers. The proposed WPM can manage the power flow of WPT systems without any control and communication devices, which improve the reliability and cost-efficiency. A 20 W WPT system with two LED loads is set up to demonstrate the effectiveness of the proposed WPM in regulating the power flow. The WPT system operates at 100 kHz.
