The Transformer Characteristics of the Active Clamp Forward Converter for Notebook Computer Adapter

노트북 컴퓨터 어탭터용 능동 클램프 포워드 컨버터 변압기 특성

The active clamp forward converter provides zero voltage switching and low voltage stress in wide input voltage range. It has a high efficiency at a high switching frequency and the clamped energy is recovered to the input stage. It is available for the power adaptor circuit of notebook computer. The adaptor with 19.5V/200W output power is designed for notebook computer. Specially, it is considered the transformer properties of the converter in design process. The organized process is checked by the validity from the test of the active clamp forward converter.
