A refrigerator including a body; a water supply device including a water supply pipe at least partially inserted into the body, and a water supply valve to open and close the water supply pipe; an ice making device including an ice making tray defining an ice making space, the ice making tray being movable so that water from the water supply pipe is accommodatable in the ice making space when the ice making tray is positioned to make ice, and a driving device to move the ice making tray; and a control unit configured to, based on a user input to execute a function of removing foreign substances contained in water from the water supply pipe, control the driving device to move the ice making tray so water is prevented from being accommodated in the ice making space, and control the water supply valve to open the water supply pipe.

Refrigerator and method of controlling the same

A power supply device is provided. The power supply device includes a rectifier circuit for rectifying an inputted alternating current power supply, a capacitor circuit comprising a first and second capacitor which are connected in series, and smoothing the alternating current power supply rectified in the rectifier circuit, an inverter for converting the output power of the capacitor circuit to a preset power and outputting same, a switch for selectively connecting a middle node of the first capacitor and the second capacitor and an end of the alternating current power, a sensor for detecting a size of the alternating current power, and a controller which confirms a power mode of the alternating current power on the basis of an output value of the sensor, and which controls the switch so that the capacitor circuit multiplies and amplifies the selectively rectified alternating current power based on the confirmed power mode.
