Abstract : In high-power Buck converters ,the circuit is in high switchingmode .Since the distributed stray parameters of the lead and non-ideal performance of the devices ,very high voltage and/or current spike appear on the switches ,which reduced the reliability of the circuits .This paper analyzed the reasons of the two kinds of spike produced and their harmand proposed several RCL snubber circuits .The analysis and designmethods of each parameter in the circuits are presented accordingly .The results of simulation and practical application prove that the snubber circuits have fine soft-switch effect and strong restraint function to the spikes .
wow,這樣子的例子太多了,很多都是有錯的,不知道有意還是無意呢,
就是一些IC廠家的規格也有錯的。。。作者: ppliu 時間: 2010-4-29 10:23 AM
