Using the CL transformer symbol and model to make a

1:0.5 turns ratio transformer with a 1H primary inductance.

Using the CL transformer symbol and model to make a 1:0.5 turns ratio transformer with a 1H primary inductance. To do this in the CL transformer, we must set N = 2.

Because it is not an ideal DC transformer, the effect of the primary inductance must be taken into account.

The frequency is set to 1 Rad/s so that the reactance of the primary inductance equals 1 Ohm, i.e. the primary voltage has been attenuated to 1/sqrt(2) of the 1V pk-pk input signal.

Because the transformer is a 2:1 step down:

V(sec) = V(pri)/2

Note that:

i) the secondary is open circuit.

ii) A 1:N turns ratio transformer with a primary inductance of Lpri will have a secondary inductance of Lpri*N^2
