On notera deux choses :. Il s'agit des diodes Schottky. The theory is that since these diodes are so fast, their recovery time is inherently shorter than in case of typical, slower rectifier diodes; also, their noise floor is lower. Then there is the other group, which says that while speed is no doubt good, Schottky diodes do not offer current capabilities of rectifier diodes, and worse still, their voltage ratings are not anywhere near those of rectifier diodes.

For example, Nelson Pass states very plainly in several of his projects that in his experience, classic heavy duty bridge rectifiers will in fact produce better results than ultra fast Schottky diode rectifiers. Personally, I agree with Mr. I would never go for ultra fast diodes in current amplifier rectification stages - fine for preamps, fine for voltage gain stages, but not good for current gain stages.

Il sera donc plus efficace,. Le montage avec selfs donne une tension moyenne aux bornes de la charge de 12,4 V. La conclusion est claire :. Search this site.
