Abstract

The experimental results and application potentials of a ZVS Forward DC-DC converter based coreless PCB transformer and coreless inductor are presented. The experimental converter, that has a maximum power of 12W, maximum switching frequency of 2.2MHz and nominal input voltage of 24V, has been successfully implemented. The coreless PCB transformer and inductor are found to have many favorable characteristics to high frequency operations due to the absence of a core loss. A power conversion efficiency of the experimental converter was measured at 70${\sim}$80%, and the output was regulated at 12V within 0.7% tolerance.

본 논문은 코어 없는 PCB(Print circuit board) 변압기와 인덕터를 이용한 ZVS (Zero voltage switching) Forward DC-DC 컨버터의 실험 결과 및 실용 가능성을 보고한 것이다. 최대출력 12W, 최대 스위칭주파수 2.2MHz, 정격 입력전압 24V를 갖는 실험용 컨버터가 검증되었다. 코어 손실이 없기 때문에 코어 없는 PCB 변압기와 인덕터가 고주파 동작에 적합하다는 것을 밝혔다 실험 컨버터는. 최저 70% 에서 80%의 전력변환 효율을 나타내었고， 12V 출력전압은 0.7% 이내에서 안정되었다.
