Abstract | Millimeter-wave tracking radars should be operated in various environmental restrictions, thus they demand more computing power and smaller size compared to conventional tracking radars. This paper presents the design and implementation of the compact power supply for millimeter-wave tracking radar applications. To meet requirements of low voltage/high current and voltage accuracy for FPGA/DSP digital circuits, Point of Load (POL) converters are used in order to enhance power density and system efficiency. LDO (Low Dropout) is applied for the output voltage under the light load condition, then the single-input-multi-output power supply with max power of 375 W and 8 outputs is developed. The proposed power supply achieves output voltage accuracy of ±2 % and noise level of <50 mVpp % under full load conditions. 밀리미터파 추적 레이더는 다양한 환경조건에서 운용 가능해야하므로 기존의 추적 레이더에 비해 동등 이상의 연산능력 및 소형화를 요구한다. 본 논문에서는 밀리미터파 추적 레이더에 적용하기 위한 소형 전원공급기 설계 및 구현방안에 대해 기술한다. FPGA/DSP 등 디지털회로의 저전압/고전류 및 전압 정밀도 요구사항 충족을 위해 Point of Load (POL) 컨버터를 적용하였으며, 전력밀도를 향상시키고 시스템 효율을 개선할 수 있다. 부하가 크지 않은 출력전압에는 LDO (Low Dropout) 등을 적용하여 최대 출력 375 W, 출력 전원 8종의 단일 입력-다중 출력 전원공급기를 개발하였다. 최대 부하 조건에서 전압정밀도 <±2 %, 잡음레벨 <50 mVpp 특성을 확인하였다. |
