Abstract:
This power source control device has a discharge slowing means (3) that slows the speed of electrical discharge current from a capacitor element (C1) to a converter (6), and after the converter (6) is controlled and the capacitor element (C1) has been charged to a predetermined voltage higher than the voltage of a first DC power source (B1), on the basis of the changes in voltage value detected by a voltage sensor (4) in the state of the on/off state of a first and second relay (SMR1, SMR2) being reversed, an abnormality of at least one of the two relays is determined.
