Circuit Maker, Trasformer

Guest
I am trying to simulate a circuit in Circuit Maker which involves a
Transformer.
But I do not know how I should enter the values for number of Turns of
the Transformer

anyone having any Ideas?

SPICE (assuming that is what it uses) only knows about inductance.

If you're working with transformers as voltage converters, as in a
familiar mains supply for example, then it's *ratios* that are key.

Simply choose from CM's list of models a transformer with an
appropriate primary/secondary turns ratio. D-click and edit it if you
want a different ratio. Here's an illustration.

You can also change primary and secondary DC resistance, leakage
inductance, and magnetizing inductance if you want. Give your edited
subcircuit a new name, as I've done in the example, so that you can
use it again quickly in future.

BTW, there's a side issue here that's always irritated me. CM offers
two symbols for its transformers. One is symmetrical (as shown top
right corner). The other always shows the fewer turns on the left,
regardless of the turns ratio, making it always look like a step-up
transformer. So I often mirror-flip it, to match my mental picture of
a real mains transformer. Of course, the name is then misleading! Or
you can choose the 'correct' name (I'd like a 240-to-40 transformer to
be called 10TO1), but then you can't flip it as you get the wrong
voltage on the secondary!

I love to cook with wine. Sometimes I even put it in the food.
