Title:
AC-DC POWER SUPPLY DEVICE AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2018/088454
Kind Code:
A1
Abstract:
This AC-DC power supply device is provided with a circuit board that is provided with an alternating current input terminal, to which an alternating current is inputted, and a direct current output terminal, from which a direct current is outputted. The AC-DC power supply device is provided with: a diode bridge that rectifies the alternating current inputted from the alternating current input terminal; an alternating current input line that electrically connects the alternating current input terminal and the diode bridge to each other; a coil connected to the diode bridge; a diode connected to the direct current output terminal; a switching line that electrically connects the coil and the diode to each other; and a switching element connected to the switching line. In the AC-DC power supply device, a part of the switching line is disposed perpendicular to a part of the alternating current input line.
