Document Type and Number:
WIPO Patent Application WO/2024/058336
Kind Code:
A1
Abstract:
The present disclosure provides a refrigerator including a control device for controlling driving of a motor and a method of controlling same. The refrigerator according to the present disclosure includes: a storage compartment; a door configured to open and close one open side of the storage compartment; a cold air supply device that generates cold air through a freeze cycle including compression, condensation, expansion, and evaporation processes of a refrigerant, and supplies the cold air to the storage compartment; a motor used to drive a compressor included in the cold air supply device; and a control device that controls driving of the motor, wherein the control device includes: an inverter unit including a plurality of switches that switch a coil through which current flows among a plurality of coils included in the motor; and a processor for square wave control of the inverter unit, wherein the processor may determine a torque correction amount used to smooth the speed of the motor, set a first conduction angle of the plurality of switches in a first mechanical angle range constituting one cycle of the mechanical angle of a rotor of the motor and a second conduction angle of the plurality of switches in a second mechanical angle range excluding the first mechanical angle range, and set the second conduction angle to be greater than the first conduction angle.
