<p>An electric power source device includes a direct current voltage source 10, a capacitor 13 connected in series with direct current voltage source 10, a DC/DC converter 19 connected to supply and receive energy between direct current voltage source 10 and capacitor 13, and a high voltage load 15 connected to both ends of a series circuit of direct current voltage source 10 and capacitor 13. A control circuit 33 of DC/DC converter 19 supplies electric power from capacitor 13 to direct current voltage source 10 when electric power is supplied to high voltage load 15 so as to reduce an electric current to be output from direct current voltage source 10 and to lighten the burden imposed on the direct current voltage source.</p> |
