The inverter includes an upper arm having a third switching element and a lower arm having a fourth switching element. The converter includes an upper arm having a first switching element and a lower arm having a second switching element. The electronic control unit is configured to, when a state where the primary-side voltage is at least equal to the specified threshold continues for a specified time or longer, i) increase the primary-side voltage by repeatedly switching the second switching element between ON and OFF state while maintaining the first switching element to be OFF state, and apply the increased voltage as the secondary-side voltage to the inverter, and ii) convert the secondary-side voltage to the AC voltage by repeatedly switching each of the third and the fourth switching element between ON and OFF state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply device","description":"A power supply device includes a battery, an inverter, a converter, an electronic control unit.
