Title:
POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/117204
Kind Code:
A1
Abstract:
A power source device according to an embodiment of the present invention converts an alternating current voltage into a direct current voltage. The power source device (100) is provided with: a rectifier circuit (A02) for rectifying an alternating current input signal; a smoothing capacitor (A03) for smoothing the rectified signal; a switch element (A08) for switching between connection and disconnection of the rectifier circuit to the smoothing capacitor; a voltage setting circuit (A05) for setting a target value of a voltage across the smoothing capacitor; a threshold setting circuit (A06) for setting a threshold for the voltage of the rectified signal; and a control circuit (A07) for controlling the switching on and off of the switch element, in accordance with an output signal from the threshold setting circuit. The control circuit turns the switch element off if the voltage of the rectified signal is not less than the threshold.
