Abstract
One-to-multiple wireless power transfer (O2M-WPT) is convenient and flexible, using a single transmitter to power multiple loads. However, existing O2M-WPT still exhibits several drawbacks: 1) the primary coil tends to burn out when there is a load open circuit or coils misalignment; 2) the compensation network cannot naturally realize constant-current (CC) or constant voltage (CV) output. In this brief, a primary multi-frequency constant-current compensation (MFCC) network is proposed to solve these problems. With the MFCC, the primary side works as a current source at multiple operating frequencies, and the receivers can achieve CC or CV output, meeting the requirements of various loads. Experimental results verify the effectiveness of the proposed MFCC network for the O2M-WPT systems.
