I need the 12vdc for my project from 220vac without tranformer and use SCR, please help me the idea. Gia, I really want to be friendly in all my posts. But it's really annoying that so many posters here do miss all the information needed to give adequate help. Can't you imagine that some more details are needed to understand what you are doing?? So, you should at least explain us the reason why you need to neglect the transfomer. And of special importance: How much current is drawn by the 12V supply? And what about the SCR? Does it mean, that you want to produce the 12V by the help of a SCR circuit? Or does your application contain a SCR section, which must be driven by the 12V circuit? Questions over questions! You did spent half a minute to formulate your post but will mislead dozens of members to spend a manifold of time to try to understand your post. Think about it. Kai |
