A method for performing switching synchronization of a bridgeless rectifier in an electric vehicle (EV) wireless power transfer system may include receiving, by an EV control module, an input voltage of a transmission-side resonance circuit from a transmission-side of the EV wireless power transfer system; calculating, by the EV control module, a phase difference between the received input voltage and a voltage or a current selected in the bridgeless rectifier and a reception-side resonance circuit; and controlling, by an EV control module, switching time points of switches included in the bridgeless rectifier to decrease the calculated phase difference. The reception-side resonance circuit may be electromagnetically coupled to the transmission-side resonance circuit, and the bridgeless rectifier may be configured to rectify an output of the reception-side resonance circuit and to output the rectified output.

Method and apparatus for performing switching synchronization for bridgeless rectifier in electric vehicle wireless power transfer system

A method for controlling wireless power transfer to an EV using a bridgeless rectifier may include detecting a phase difference between an input voltage of a transmission-side resonance circuit and an output voltage of a reception-side resonance circuit; after detecting the phase difference, predicting a resonance frequency change direction according to a preconfigured design condition; and controlling switching time points of switches included in the bridgeless rectifier in a direction compensating for the predicted change direction.

Method and apparatus for controlling wireless power transfer to electric vehicle using bridgeless rectifier

An electronic device according to one embodiment of the disclosure includes a display, a memory that stores an application for editing an image, and a processor that outputs the image through the application onto the display. The processor may be configured to output, on the display, the image, a first guide indicating an area to be cropped in the image, and a preview corresponding to the first guide in a first mode of the application. The processor may output, on the display, an image changed in accordance with a second mode in response to a user input to change a mode from the first mode to the second mode. The processor may output a second guide corresponding to the second mode on the display such that the preview corresponding to the first guide is output. In addition, various embodiments understood through the specification are possible.

Method and electronic device for outputting guide

An electronic device is provided. The electronic device includes a display, a memory configured to store instructions, and a processor, wherein the processor is configured to execute the stored instructions to display an image and a user interface (UI) representing depth information of the image through the display in response to a first user input for editing the image, receive a second user input for selecting an object to be added in the image, display at least a part of the object in the image based on a depth value of the object and depth information of a first region in which the object is located in the image, and display an indicator representing the depth value of the object in the UI.

Apparatus for editing image using depth map and method thereof

An electronic device is provided. The electronic device includes a memory storing spherical content, at least a portion of which is provided in the shape of at least a portion of a sphere with respect to a central point of an image, a display configured to output the spherical content, and a processor configured to be electrically connected with the memory and the display.
