Abstract
This work proposes the use of inductive links in order to wirelessly power autonomous sensors. In order to increase the powering distance and the power efficiency, resonant tanks were considered. To drive the transmitting resonant network, a commercial class D amplifier was used. Working frequency was restricted to 150 kHz. Commercial magnetic-core coils were selected as they provide high coil values and quality factors in a small-size factor, which is a requirement for the intended application....
