본 논문에서는 부스트 및 벅-부스트 컨버터에 대해 주파수 응답에 대한 리플 효과를 무시할 수 없음을 명확히 하고, 파형의 형태에 따라 위상 지연 또는 위상 리드가 나타나는 예상치 못한 특성을 유발함을 밝힙니다. PWM 회로의 램프 생성기. 결국 동일한 회로 구성에서도 램프 발생기의 톱니파형의 경사방향(정방향 또는 역방향)에 따라 안정성을 위한 위상여유가 급격하게 변화하게 된다. 파급효과에 대하여 일반분석 모델을 제안하고 이를 부스트 및 벅-부스트 컨버터에 대해 분석한다. 그 결과 리플 효과는 주로 기울기의 변화와 리플의 평균에 의해 발생함을 확인하였고, 두 컨버터 모두 램프 발생기의 톱니파형의 기울기 방향에 대해 비대칭 특성을 가지며, 일반 경사 방향보다 역경사 방향의 경우 안정성에 더 유리합니다. 또한, 톱니파형의 형태에 따라 컨버터 출력 커패시터의 ESR이 주파수 응답에 미치는 영향이 다르다는 것을 밝혔다. 제안된 분석 방법은 실험과 시뮬레이션을 통해 검증되었다.

Abstract: In this paper we clarify for the boost and the buck-boost converter that the ripple effect is not ignorable for the frequency response, and reveal that it causes the unexpected characteristics where either the phase lag or the phase lead appears depending on the shape of waveform of the ramp generator in the PWM circuit. Eventually the phase margin for the stability drastically changes depending on the slope direction (normal or reverse) of the sawtooth waveform of the ramp generator even in the same circuit configuration. For the ripple effects we propose the general analysis model and analyze them of the boost and the buck-boost converters. As the result we identify that the ripple effects are caused mainly by the variation of the slope and the average of the ripple, and reveal that the both converters have the asymmetric characteristics for the slope direction of the sawtooth waveform of the ramp generator and there is more advantage for the stability in case of the reverse slope direction than in case of the normal one. It also clarified that the effect of ESR of the output capacitor of the converter on the frequency response is different according to the shape of the sawtooth waveforms. The proposed analysis method is validated by the experiments and simulations.
