摘要 <p>PROBLEM TO BE SOLVED: To inhibit a rush current flow to a load when an output current value or an output voltage value of a power circuit is changed.SOLUTION: A drive device 10 includes: a power circuit 20 capable of changing the output current value of an output terminal having a load 2 connected thereto; an output capacitor 15 connected between the output terminal of the power circuit 20 and a reference potential section 19; a switching element 17 connected between the output terminal of the power circuit 20 and the reference potential section 19; and a control unit 11 for controlling the output current value of the power circuit 20. The control unit 11 switches on/off the switching element 17, and controls the output current value of the power circuit 20 during a period when the switching element 17 is switched on in such a manner that the voltage of the output terminal of the power circuit 20 during the period of concern becomes a value lower than and including a voltage which is applied to the load 2 during a period when the switching element 17 is switched off after the period of concern.</p>
