The disclosure relates to a communication technique and system after 4G systems for combining a 5G communication system with IoT technology to support higher data rates. Based on 5G communication and IoT-related technologies, the disclosure can be applied to intelligent services (e.g., smart home, smart building, smart city, smart or connected car, healthcare, digital education, retail, security, and safety). A converter may include: a first printed circuit board having a first controller for power conversion disposed on an inner surface of the first printed circuit board, the inner surface of the first printed circuit board comprised in an inner surface of the converter; a second printed circuit board having a second controller for power conversion disposed on an inner surface of the second printed circuit board, the inner surface of the second printed circuit board facing the inner surface of the first printed circuit board and comprised in the inner surface of the converter; first connectors disposed on the inner surface of the first printed circuit board; and second connectors disposed on the inner surface of the second printed circuit board, the second connectors configured to be coupled with the first connectors.

Converter including printed circuit board and power conversion module including converter

The purpose of the present disclosure is to protect a power circuit of a base station in a wireless communication system, the base station comprising: at least one module for processing a signal; and the power circuit for supplying power to the at least one module. The power circuit comprises a transformer, a rectifier circuit and a smoothing circuit, and the power circuit reduces the ratio of an on-section of the rectifier circuit if a reverse current from the at least one module is detected.

Device and method for protecting power circuit of base station in wireless communication system

A system and method are provided for controlling a temperature of a communication base station system or similar device. The method includes collecting temperature information from at least one location in a system such as a base station, setting hysteresis-based temperature settings for a first base temperature for starting to operate a temperature control device in the base station, and a second base temperature for terminating operation of the temperature control device based on the collected temperature information, generating temperature control information by comparing the set hysteresis-based temperature and the collected temperature information, and controlling the temperature control device and/or power to the base station by using the temperature control information.

Method and device for controlling temperature

The present disclosure relates to a communication scheme and system for converging a 5generation (5G) communication system for supporting a data rate higher than that of a 4generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars, connected cars, health care, digital education, retails, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. An operation method of a power supply is provided. The operation method includes calculating an inter-phase current deviation by averaging current deviations between a first phase current and a second phase current, comparing the inter-phase current deviation with a first threshold value, adjusting a pulse width modulation (PWM) duty value of at least one of a first phase and a second phase according to a result of the comparing, and compensating for inter-phase current deviation according to the adjusted PWM duty value.
