scuba14c Posted May 16, 2005 Report Share Posted May 16, 2005 I have been trying to build a boost converter, but am having problems. If you aren't familiar with these, they use an inductor, diode, a semiconducting switch, and a 555 timer. The voltage builds up in the inductor, and is pumped into the capacitors. The diode prevents it from flowing out. I can get it to charge to 45V, and then it won't go any farther. With a 12V input, it does work, but should be able to charge to a much higher voltage. The load on the capacitor doesn't matter either. I have used 100uF and 3600uF banks and both stop at 45V. I have a 100uH inductor and a fast recovery diode. This is the schematic I built it off of...
