Hi,
I have an auto transformer with three winding:
1- 0 ~ 15 for circuit power supply
2- 0 ~ 20 for step up or step down to main winding (0-40-140-220)
3- 0 ~ 40 ~ 140 ~ 220 main winding
this can take input from 90 volts to 265 and produce 220 volt output.
Problem: I do not understand how it can step up and down in mentioned range?
I do not have electronics background, just programming!
