一种具有减小环流和整流器电压应力的高效率三电平DC-DC变换器

This paper proposes a high-efficiency three-level (TL) dc-dc converter with reduced circulating current and rectifier voltage stress by using coupled inductor in the rectifier circuit. Because of decreased circulating current, the conduction loss in the primary circuit is reduced. In addition, since the rectifier diodes with low forward voltage drop can be employed due to the small voltage stress,...
