摘要: An efficient active LC snubber for multi-output converters with flyback synchronous rectifier (SR) is proposed in this paper. The can be used to reset transformer and suppress switching surges. Besides, by storing surge energy the then releasing it SR, converter achieve high efficiency. For a forward 90.8%, maximum output efficiency, achieved. Experimental results also show that efficiency of higher than active-clamped-based converters.
