Hi,
sometimes I´ve seen at SMPS a wave form on the power line instead of a straight clear line with the scope. I know probably it has to do with a bad filtering of signal at secondary but sometimes it´s very difficult to remove it even making filter better. Is it like a feedback from inductor of the transformer?
