摘要：
This paper presents the carrier harmonic modulation (CHM) for near-field data communication during wireless power transmission. The proposed CHM does not increase the coil dimension, and an additional data driver is not required. Compare to conventional modulation techniques such as frequency-shift keying (FSK) and amplitude-shift keying (ASK), the power delivered to the load (PDL) of CHM is independent of the data transmission. The prototype CHM provides a data rate of 1.1 Mbps while the power carrier frequency is also 1.1 MHz. It achieved a maximum PDL of 641 mW and the system efficiency of 17% with a 30 mm TX/RX coil diameter.
