초록

군 전술정보통신체계(TICN: Tactical Information and Communication Network)의 하위체계라 할 수 있는 전술다기능단말기(TMFT: Tactical Multi-Functional Terminal)는 개인 사용자에게 음성통화, 데이터 송수신, 멀티미디어 서비스를 제공하는 체계이다. 2011년도 개발당시 전술다기능단말기 전원회로는 충전IC를 거쳐 각각의 소자에 전원을 공급하는 구조였으나, 새로 개선된 전원회로는 충전IC를 별도로 구성하지 않고 PMIC(Power Management Integrated Circuit)를 통해 각 소자에 전원이 공급되도록 하였다. 본 논문에서는 개발단계의 전원회로설계가 적용된 전술다기능단말기와 신규 PMIC를 적용한 전술다기능단말기의 전원구조를 비교하였다. 그리고 소비전류, 충전시간, 충전 시 단말기 온도상승 등의 성능평가를 통해서 설계 개선 및 부품의 적합성을 검증하였다.

The TMFT, a sub-system of TINC, provides voice calls, data transmission and reception, and multimedia services to individual users. At the time of development in 2011, the power circuit of the TMFT was designed to electrical power supply to each device via a charger IC. However, the newly improved power supply circuit allows power to be supplied to each device through the PMIC without configuring the charger IC separately. In this paper, the power circuit design structure of TMFT applied in the development stage and the improved power circuit design structure were compared. And we verified through experiments whether the improved power circuit can be applied to TMFT. The experimental method was verified by directly comparing the current consumption test, charge time comparison test, and rising temperature test during charging each of before and after improvement terminals.
