Beschreibung
Zusammenfassung:	A power source device includes: a switching section switching an input voltage supplied to a load section; a smoothing inductor section smoothing and outputting an output current to be supplied to the load section in accordance with a switching of the switching section; a first inductor section decreasing an output inductance value of the smoothing inductor section; a second inductor section increasing the output inductance value of the smoothing inductor section; an electromagnetic induction activating section activating the electromagnetic induction between the smoothing inductor section and the first or the second inductor section; a load current fluctuation detecting section detecting a steep fluctuation in a load current; and a control section controlling the electromagnetic induction activating section so as to activate the electromagnetic induction between the smoothing inductor section and the first or the second inductor section when the steep fluctuation of the load current is detected.
