POWER SUPPLY DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/075239

Kind Code:

A1

Abstract:

A power supply device according to the embodiment supplies DC power to an electrolytic cell that generates hydrogen through electrolysis. This power supply device comprises: a self-excited power converter including a first output terminal and a second output terminal that outputs a positive voltage with respect to the first output terminal; a reactor serially connected to at least one of the first output terminal and the second output terminal; and a filter circuit connected between an anode and a cathode of the electrolytic cell. The filter circuit is a low-pass filter. The cutoff frequency of the filter circuit is set to be lower than the switching frequency of the power converter.
