High voltage transformers can be a bit tricky to design. When you’re trying to target a particular voltage one needs to account for things such as DCR losses in the windings. This is important when regulation is important. The following design procedure will get you close in the ballpark for your needs. I will account…
A super quiet EP13 size flyback transformer. Primary inductance is 4.31mH +/- 10%. Switching frequency is 60 KHz minimum. The input is rated at 120V. There are 2 outputs rated at 2.5V/600mA and an aux rated at 17V/20mA. The power rating is 3.4VA, but it could handle twice that at 6.8VA. The design reduces electrical…
