Abstract: In embodiments, a power supply circuit is provided. The power supply circuit may comprise a plurality of direct current direct current (DCDC) converter circuits and a pulse width modulation (PWM) controller operatively connected to the plurality of DCDC converter circuits. The PWM controller may be configured to obtain a current voltage of a power amplifier. The PWM controller may be configured to obtain a reference voltage for the power amplifier. The PWM controller may be configured to generate PWM control signals for the plurality of DCDC converter circuits based on a difference between the current voltage and the reference voltage. The PWM controller may be configured to provide the PWM control signals to the plurality of DCDC converter circuits. Each DCDC converter circuit of the plurality of DCDC converter circuits may comprise a transformer, a primary active clamping circuit connected to a primary end of the transformer, and a secondary resonance converter circuit connected to a secondary end of the transformer. The secondary resonance converter circuit may comprise a diode configured to provide a regeneration current from the secondary end of the transformer to an output end of the secondary resonance converter circuit.

Abstract: 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.

Abstract: The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (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.
