밧데리 충전을 위한 새로운 AC/DC 컨버터에 대한 연구
鄭敎範,金台根 弘益大學校 産業技術硏究所 2004 産業技術 Vol.14 No.-
New AC/DC power converter for battery charging is proposed. The converter with four MOSFET, a diode and an inductor transfers energy from AC current source to DC battery. In order to make the converter efficient and compact, the inductance as small as possible is chosen. The converter has a ultimately short interval of turning MOSFETs on, which makes the parasitic capacitors of MOSFETs and a diode take effects on the converter operation. The analysis of the converter operation and the calculation of the energy losses are in detail performed, which is proved with the computer simulation study.
