The input unit inputs an AC input. The rectifier circuit has a smoothing capacitor and converts the AC input into a rectified output. The switching circuit switches between an ON-state in which input impedance is low and an OFF-state in which input impedance is higher than that in the ON-state. The controller sets a modulation ratio such that, when controlling the switching circuit to switch between the ON-state and the OFF-state, at least a portion of a period, in which the modulation width of the modulation duty ratio becomes maximum, is included in a period from a time when an input current inputted to the smoothing capacitor is generated to a time when the voltage of the smoothing capacitor reaches a maximum value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device, driving device, control method, and storage medium","description":"A power supply device is provided with an output unit, an input unit, a rectifier circuit, a switching circuit, and a controller.
