Abstract

This study provides a novel adaptive pulse waveform modulation (aPWFM) for wireless power transmission (WPT) for biomedical applications. A novel wireless aPWFM powering approach is proposed to improve the power conversion efficiency (PCE) for low average input power. When the average power input is lower than -15 dBm, the PCE can be improved 3.5-fold. LED load experiments were performed for performance verification and shows that implementing the aWPFM technology significantly improved PCE from 1.27% to 33.96% at an average input power of -8 dBm.
