<p>An electric power source device is provided with a direct current voltage source (10), a capacitor (13) connected in series with the direct current voltage source (10), a DC/DC converter (19) connected to supply and receive energy between the direct current voltage source (10) and the capacitor (13), and a high voltage load (15) connected with both end terminals of a series circuit of the direct current voltage source (10) and the capacitor (13), wherein a control circuit (33) of the DC/DC converter (19) supplies the electric power from the capacitor (13) to the direct current voltage source (10) when it supplies the electric power to high voltage load (15), so that the electric power source device reduces an output electric current from the direct current voltage source (10) and lightens the burden imposed on it.</p> |
