Lessons 1 through 5 are now complete and posted. I have started on a set of lessons for blind users. These are explained in the book I am studying to learn LT Spice. However, because spice started in the days of punched card input and line printer output it still retains a method of text based input and data output. On the surface LT Spice does not appear to be blind friendly. I suspect most of the changes were internal.Īn updated note to my blind friends. So far I haven't run into any user interface differences between Version IV and XVII.

The inductance ratio corresponds to the turns ratio as follows:įor example, for a 1:3 and 1:2 turns ratios, enter inductance values to produce a one to nine and one to four ratios:Īnalog Devices is in the process of updating our website.

LTspice simulates the transformer using individual component values, in this case, the inductance of the individual inductors, not the turns ratio of the transformer.

Adding the K statement displays the phasing dot of the included inductors.

Adjust the inductor positions to match the transformer polarity by using move (F7), rotate (Ctrl + R) and mirror (Ctrl + E) commands.

The following is an equivalent to the statement above: Only a single K statement is needed per transformer LTspice applies a single coupling coefficient to all inductors within a transformer. For practical circuits, it is recommended you start with a coupling coefficient of 1. The last entry in the K statement is the coupling coefficient, which can vary between 0 and 1, where 1 represents no leakage inductance.

Couple them using a single mutual inductance (K) statement via a SPICE directive:.

Draft an inductor for each transformer winding.
