Abstract

In this paper, the energy saving on mobile communication repeater is studied. DB(Dual Band) small repeater, which is currently used in the field for indoor coverage, is adopted as a test unit. For reducing the power consumption, PFC (Power Factor Correction) is included on SMPS (Switching Mode Power Supply) of the DB small repeater. The test results show that approximately 38.9% of the power consumption is reduced comparing with the repeater without PFC. It means that approximately 230.43kWh per unit can be saved annually.

본 논문에서 이동통신 중계기를 위한 에너지 절감방법에 대한 연구를 수행하였다. 현재 실제 현장에서 서비스하고 있는 DB(Dual Band)소형 중계기에 있는 SMPS(Switching Mode Power Supply)에 PFC(Power Factor Correction)를 추가하여 전력소모를 감소하였으며, 이를 실제 구현하여 검증함으로써 실증된 결과를 도출하였다. 실증결과 장비 1식당 약 38.9% 피상전력 개선효과를 확인하였으며, 이를 연간으로 환산해 보면 약 230.43kWh의 에너지 절감효과가 있다.
