초록

본 논문에서는 단일칩 마이컴을 이용한 위상변위 방식 직류-직류 전력변환기를 제안한다. 제안한 전력변환기의 1차측은 위상변위 방식에 의하여 단극성 펄스폭변조(unipolar PWM)로 동작하는 풀브리지 전력구조이며, 2차측은 4개의 다이오드로 구성된 풀브리지 전파정류기이다. 제안한 전력변환기의 제어는 단일칩 마이컴에 의해 수행되고, 그 MOSFET 스위치들은 부트스트랩 회로에 의해 구동된다. 그래서 전력변환기의 전체 시스템은 간단하다. 제안한 전력변환기는 공진회로와 저지커패시터를 이용하여 고효율을 달성한다. 본 논문에서는 먼저, 제안한 전력변환기의 전력회로의 동작을 각 동작모드를 따라 설명한다. 그리고 제안한 전력변환기의 전력회로 설계방식을 보이고 제안한 전력변환기를 동작시키는 마이컴 상의 소프트웨어 제어 알고리즘과 피드백 및 스위치 구동 회로에 관하여 간략히 설명한다. 그 후, 본 논문에서 제시한 설계와 구현방식에 의하여 설계하고 제작된 시제품 전력변환기의 실험결과를 통하여 제안한 전력변환기의 동작 특성을 입증한다. 실험결과에서 약 92% 정도의 최고 효율을 얻었다.

This paper presents the phase-shift full-bridge DC-DC converter using the one-chip micom. The proposed converter primary is the full-bridge power topology that operates with the unipolar pulse-width modulation (PWM) by the phase-shift method, and the secondary is the full-bridge full-wave rectifier composed of four diodes. The control of proposed converter is performed by the one-chip micom and its MOSFET switches are driven by the bootstrap circuit. Thus the total system of proposed converter is simple. The proposed converter achieves high-efficiency using the resonant circuit and blocking capacitor. In this paper, first, the power-circuit operation of proposed converter is explained according to each operation mode. And the power-circuit design method of proposed converter is shown, and the software control algorithm on the micom and the feedback and switch drive circuits operating the proposed converter are described, briefly. Then, the operation characteristics of proposed converter are validated through the experimental results of a designed and implemented prototype converter by the shown design and implementation method in this paper. The highest efficiency in the results was about 92%.
