The transmitted power is controlled so that an output voltage detected in a predetermined ratio can be equal to a reference voltage. A reduction signal is outputted when the output voltage decreases below a threshold. A presence or absence of an abnormality in a capacitance connected to the output terminal or a load current in a load connected to the output terminal is determined, when the output voltage is equal to the target voltage, by changing at least one of the detection ratio and the reference voltage so that the output voltage can transition from a target voltage higher than the threshold toward a middle voltage lower than the threshold only during a predetermined time period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply apparatus","description":"In a power supply apparatus, power is transmitted from its input terminal to its output terminal.
