Title:
POWER SUPPLY DEVICE AND BEARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053197
Kind Code:
A1
Abstract:
A power supply device (17) comprises a first circuit (61) and a converter (53). The first circuit (61) converts alternating-current voltage to a first direct-current voltage and outputs the first direct-current voltage. The converter (53) outputs a second direct-current voltage produced by adjusting the first direct-current voltage to a first voltage range to an electronic circuit (54). The input voltage of the converter (53) is set to a second voltage range. The first circuit (61) converts the alternating-current voltage to a first direct-current voltage adjusted to the second voltage range.
