Rectification of line voltage? Answered
I need to get 230V DC for controlling the brightness of the bulb using a mosfet transistor. The problem is that the rectified line voltage'll get 230 * sqrt (2) = 325 V .. it is too much. I didn't find a transformer AC / AC 230/160 V or step-down IO DC / DC 320/230 V on a market. How can it be solved? Sorry for my english. Thank you for answer.
