Abstract

In this paper, a detailed analysis of zero current or zero voltage switching boost converter using a single switch is described. The proposed topology is capable of decreasing switching loss of IGBT device using soft switching technique. As a results, it can be reduced size and weight of passive elements. Based on the mode analysis, practical design considerations are presented. We confirm the converter topology, principle of operation and simulation results obtained from the PSIM software. The performance of the proposed converter is verified by with 1kW(400V, 2.5A) prototype circuit operated at 30kHz.

이 논문에서는 단일 스위치를 사용하여 영전류 또는 영전압 스위칭 하는 부스트 컨버터를 기술하였다. 제안된 토폴로지는 소프트스위칭 함으로써 IGBT소자의 스위칭 손실을 감소시킬 수 있다. 이에 따라 수동소자의 크기와 무게를 줄일 수 있다. 모드 해석을 근거로 하여 실제적인 고려되어야할 설계를 제시하였다. 컨버터 토폴로지 동작원리를 설명하고 PSIM 소프트웨어 설계를 통하여 시뮬레이션 결과를 확인하였다. 제안된 컨버터의 성능은 30kHz에서 동작하는 1kW(400V, 2.5A) 실험실수준 레벨에서 증명하였다.
