Title:
POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/014044
Kind Code:
A1
Abstract:
A voltage transformation circuit (47) in a power supply device (12) transforms the terminal voltage of a capacitor (46) and outputs the transformed voltage to a FET (42). The connection node located between the source of the FET (42) and the voltage transformation circuit (47) has the source of a FET (43) connected thereto. A detection circuit (48) for detecting the output voltage of the voltage transformation circuit (47) is connected in series to the FET (43). The voltage transformation circuit (47) adjusts the output voltage of the voltage transformation circuit (47) according to the voltage detected by the detection circuit (48).
