Abstract: An electronic device and method for providing a communication service are provided. The method of operating an electronic device includes: receiving a first signal transmitted through a first band and a second signal transmitted through a second band; determining a communication mode of the electronic device for processing the first signal and the second signal based on device information or environment information of the electronic device; and processing the first signal and the second signal using at least one of a first modem or a second modem functionally connected to the electronic device based on the communication mode, wherein the processing of the first signal and the second signal includes: processing, when the communication mode is a first mode, the first signal in the first modem and the second signal in the second modem; and processing, when the communication mode is a second mode, the first signal and the second signal in the first modem.

Abstract: An apparatus for balancing a voltage of a direct current (DC) link capacitor of an inverter is provided. The apparatus of the present disclosure includes a switching unit connected to a node (a reference point) between the first and second resistors, which are connected in series to each other, and a node (a neutral point) between the first and second capacitors, which are connected in series to each other, and configured to short and open between the reference point and the neutral point, and a control unit configured to control the switching unit to short between the reference point and the neutral point when a voltage of the reference point (a reference point voltage) and a voltage of the neutral point (a neutral point voltage) are different from each other.

Abstract: An apparatus and method for providing an LTE service in an electronic device. The method includes: transmitting or receiving a voice signal through a first antenna and a data signal through a second antenna when the electronic device provides a multi-communication service. At least one switch connects at least one antenna and at least one communication interface with each other. When the electronic device provides a single communication service, transmitting or receiving a data signal or a voice signal through the first antenna, using the at least one switch.
