摘要： A power supply includes: a converter circuit including boost circuits, the converter circuit boosting a voltage output from a power source; a current detector that detects a first current flowing between the power source and the converter circuit; current detectors that each detect a second current, the second current being a sum current of currents flowing in switching elements of the boost circuits; and overcurrent determiners that determine whether the second currents are overcurrent on the basis of detection values of the second currents. When a result of the determination made by corresponding one of the overcurrent determiners indicates overcurrent, the boost circuits stop operating.

摘要： An outdoor unit includes a housing, a heat exchanger, an electric component box, a substrate, and a heat dissipator including multiple fins. The fins each have a first end situated in a windward side of an air passage formed between adjacent ones of the fins, and the first end faces the electric component box. When the heat dissipator and the electric component box are viewed from above, a first clearance gap having a first width and a second clearance gap having a second width greater than the first width are formed between the first end and the electric component box. The second clearance gap is situated closer to a back panel than the first clearance gap.
