본문

본 논문에서는 강압형 DC-DC 컨버터의 성능 개선을 위한 스위칭 기법인 2차 SDSDM(Space Dithered Sigma-Delta Modulation)방식을 제안한다. PWM 방식은 일정 스위칭 주파수 대역에서의 고조파로 인해 소음, 전자파 장애, 스위칭 손실 등을 초래한다. 이러한 문제를 해결하기 위한 DSDM 방식의 일종인 1차 SDSDM은 랜덤 디더(Random Dither) 발생기가 1차 SDM의 양자화기(quatizer) 입력 단에 위치하여 스위칭 주파수가 분산된다. 강압형 DC/DC 컨버터에 제안하는 2차 SDSDM의 방식을 적용한 실험 결과를 통해 타당성을 검증한다.
