Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/116509
Kind Code:
A1
Abstract:
An air conditioner (100) comprising: a converter unit (13), which has a first and a second input terminal (131, 132), the second input terminal being connected to a commercial AC power supply (1), and which converts a first AC voltage input from the first and second input terminals to DC voltage, which is then output; an inrush current limiting circuit (8), which has a plurality of resistors (2, 5) connected between the commercial AC power supply and the first input terminal, and a plurality of relays (4, 7) capable of short-circuiting or opening both ends of the respective resistors; an inverter unit (14), which converts the DC voltage output by the converter unit to a second AC voltage, which is then supplied to a motor (21); a temperature detection unit (9) for detecting the temperature of the resistors; and a microcomputer (50) which, after a signal related to operation of the motor is received and before operating the converter unit and the inverter unit, controls the relays on the basis of a comparison between the temperature and a threshold value.
