| With LTspice, you can use one of the circuits shown below. | |

| How did you make the transformer model?

| It's 3 inductors. K1 specifies the coefficient of coupling. Look up "mutual inductance" in the help section. Also look up "transformer model". I used K=1, which would be an ideal transformer, but in the real world, it will always be somewhat less. K=0 is no coupling. I chose the primary inductance to be 10 Henries, just to keep the no-load primary current low. Practical values may be lower. My inductors have series resistance incorporated in them, but you have to load the file into LTspice and right-click on them to see the values. I think I arbitrarily made them all 1 ohm. As you know, the inductance is proportional to the square of the number of turns, and the voltage ratio is proportional to the turns ratio, so a 100:1 inductance ratio yields a 10:1 voltage ratio.
