Beschreibung
Zusammenfassung:	A DC power supply device capable of preventing voltage oscillation of a power supply path to a motor control device is provided. The DC power supply device includes a power supply unit (such as an AC/DC converter) that outputs a DC and a filter circuit that detects a voltage fluctuation of the DC output from the power supply unit and adjusts impedance of own circuit such that the voltage fluctuation of the DC is prevented based on a detection result.
