Transmitter configuration to improve resonant coupling efficiency of a wireless power transfer system consisting of misaligned coils


Resonant coupling efficiency (RCE) in an inductively coupled near-field wireless power transfer (WPT) system is proportional to quality factor of the transmitter and receiver resonators, and square of coupling coefficient between them. The coupling between transmitter and receiver is highest when the two coils are perfectly aligned. However, in real-life… (More)
