    Abstract: An electronic device and method are disclosed. The electronic device includes a display, a camera module having first and second cameras having first and second viewing angles, respectively, and a processor. The processor implements the method, including: acquiring a first image with a first magnification using the first camera, and displaying the first image on the display, while acquiring the first image, receiving an input requesting changing an image acquisition magnification of the camera module from the first magnification to a second magnification, changing a distance between the first camera and the second camera in response to the input, upon detecting that the changed distance between the first camera and the second camera is less than or equal to a threshold distance, switching from the first camera to the second camera, and acquiring a second image using the second camera, and display the acquired second image on the display.

    Abstract: A power supply capable of protecting a rectifier circuit using a switching element from an overvoltage or an overcurrent is provided. The power supply includes a power input terminal; an output capacitor; a synchronous rectifier configured to rectify an AC voltage input through the power input terminal; a converter configured to convert the rectified AC voltage into a DC voltage following a preset voltage and supply the DC voltage to the output capacitor; and a protection circuit provided between the power input terminal and the output capacitor, and configured to supply an AC voltage higher than the voltage charged in the output capacitor to the output capacitor by bypassing the synchronous rectifier.

    Abstract: An electronic device comprising: a power supply apparatus including a first converter configured to generate driving power and a second converter configured to generate first standby voltage and second standby voltage; and a main body operated based on the driving power and the second standby power received from the power supply apparatus. The second converter is configured to: during a normal mode operation and a standby mode operation, obtain the first standby voltage and adjust the first standby power based on the obtained standby power; and during the standby mode operation, obtain the second standby voltage; and in response to the obtained second standby voltage being equal to or less than a reference level, perform the normal mode operation to control the first standby voltage to be maintained at a first voltage level and control the second standby voltage to be maintained at a second voltage level.
