Transformer Windings?

SpaceNugget · July 28, 2014

Hello, I am trying to wind my own transformer for a power supply that I am making.

I am having trouble finding resources on the optimal number of windings. I know the ratio that I need to supply the correct voltage, but how do you decide what is the correct multiple of the ratio for a given frequency and load?

for example, 60hz 115vac to 24vac with a 3A load you would need a ratio of roughly 5/1 to account for voltage drop. I have never seen a transformer with one winding on one side and five on the other. clearly that would not work well.In which case, how do you calculate which is more efficient, 500 - 100, 1000 - 200 so on and so forth.

I know this is a rather unusual request compared to most threads in this section, but I did not see a better place to ask.

If there is an electrical engineering forum or something, try asking there. People here will be able to help a little but probably don't have the knowledge of an electrical engineer. You may receive better help there. Good luck on your project

Not saying people here don't know, just saying electrical engineers may know more
