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.
