동기정류기를 이용한 저전압/대전류용 DC-DC 컨버터
The Low Voltage and High Current DC-DC Converter Using Synchronous Rectifier
초록
In this Paper, we report the experimental results of the Forward-flyback U-U converter with current doubler and synchronous rectifier. The experimental converter, that has a output voltage 3.3V, output current 20A, maximum power of 66W, switching frequency of 290kHz and input voltage range of 36-75V, has been successfully implemented. As a result, in the entire voltage range the measured full load efficiency was above 85
