回复 言高手低 的帖子
看来大家对火牛很热啊,眼高兄对制作工艺很内行。大家都来交流。
记得几年前PLITRON 开发了一项专利技术NBT (Plitron NBT transformers are built in toroidal shape, thus offering all the advantages of toroidal transformer technology.
Toroidal transformers offer higher efficiency, smaller physical size and weight, and provide less audible hum and lower stray fields compared to typical EI transformers of equivalent power rating. Toroidal transformers are the fastest growing component in the magnetics and transformer industry. )是利用变压器一二次绕组间的漏电感、内部电容和内部电阻形成一个低通滤波,并通过绕组的设计,设定一个补偿绕组,滤除差模噪声,并可以从800Hz开始,滤除存在截止频率的更高次谐波。
