Abstract
To perform wireless power transfer without needing a feedback coil, an electronic component includes: a drive transistor to be connected in series to a resonant circuit, the resonant circuit including a feeding coil for feeding power to a receiving coil and a resonant capacitor configured to resonate with the feeding coil; and a drive control section for controlling the drive transistor. The drive control section includes an ON-signal generation section for generating, when a potential difference across the drive transistor falls within a given threshold range, a control signal for controlling the drive transistor to a conductive state for a predetermined first period and thereafter controlling the drive transistor to a non-conductive state.
