Abstract

See full text

There is provided an air-conditioning apparatus including an auxiliary power supply that, when a voltage from an overhead line extending over sections powered by different power sources is stepped down with a transformer, converts the voltage into a low-voltage DC voltage and that, when a voltage from the overhead line is a DC voltage, is directly fed with the voltage and converts it into the low-voltage DC voltage that is the same as the converted DC voltage, and further including an inverter device that converts the DC voltage from the auxiliary power supply into an AC voltage and that supplies the AC voltage to a drive unit of a refrigeration cycle apparatus.
