Title:
POWER SUPPLY DEVICE AND SENSOR DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/207561
Kind Code:
A1
Abstract:
This power supply device is provided with a transmission unit for outputting an AC signal corresponding to the intensity of external force, a rectifying output unit for converting the AC signal into a pulsed DC first signal, a rectifying and smoothing output unit for converting the AC signal into a second signal that is closer to direct current than the first signal, a starting unit for outputting a starting signal, and a control unit that is started by the starting signal. The starting unit has a first terminal that is electrically connected to the rectifying output unit and a second terminal that is electrically connected to the rectifying and smoothing output unit, and outputs the starting signal if the voltage applied to the first terminal is greater than or equal to the voltage applied to the second terminal. This power supply device is capable of reliably starting the control unit.
