초록

본 논문에서는 능동 클램프 풀브릿지 Boost 컨버터에 관한 DC 모델링과 AC 모델링 과정에 대하여 기술한다. 동작 원리로부터 이 컨버터의 교류 부분을 등가의 직류 부분으로 바꾸고 반도체 스위치를 재배치하여 개념적인 등가 회로가 유도된다. 유도된 등가회로는 CCM(Continuous conduction mode) Boost 컨버터와 DCM(Discontinuous conduction mode) Buck 컨버터로 표현된다. 유도된 등가회로의 각 스위치 부분을 PWM 스위치 모델로 대체하여 DC 모델 및 AC 모델이 완성된다. 이론적인 DC 및 AC 모델링 결과는 실험이나 SIMPLIS 시뮬레이션을 통해 검증된다.

In this paper, a DC and small-signal AC modeling for the active-clamp, ful1-bridge boost converter is described. Based on the operation principle, the ac part of the converter can be replaced by a dc counterpart. Then, a conceptual equivalent circuit is derived by rearranging the switches. The equivalent circuit for this converter consists of CCM(Continuous conduction mode) boost and DCM(Discontinuous conduction mode) buck converter. The analyses for the equivalent CCM boost and DCM buck converter are done using the model of PWM switch. The theoretical modeling results are confirmed through experiment or SIMPLIS simulation.
