Save the file somewhere convenient for LTSpice such as C:\LTC\LIB\SUB. This file will grow over time, the next transformer model you save can be added to the same file. In your main spice model add a spice directive ( click on the .op tool button etc ) that says ".inc MyTransformers.lib" This lets spice find the file.

There are a number of ways to model a multiple-winding transformer in SPICE, but I have chosen to normalize all windings to a one turn linking connection, terminal Vc. The SPICE model below is for a four winding transformer having a 10 turn push-pull primary winding and two 1 turn secondary windings. In the SPICE model, each section

Here is the simple approach to simulate a transformer in LTspice IV: Draft an inductor for each transformer winding Couple them using a single mutual inductance (K) statement via a SPICE directive: K1 L1 L2 L3 1 The last entry in the K statement is the coupling coefficient, which can vary between 0 and 1, where 1 represents no leaka

In LTSpice that would be, for example, the Spice directive for a coupling coefficient of perhaps .99995 Your "completed" transformer would be L1 = 12Hy + 25 ohms L2 = 12Hy + 25 ohms L3 = 64mHy + .13 ohms L4 = 64mHy + .13 ohms K1 L1 L2 L3 L4 .99995 The last is the spice directive for coupling.

Table 2. Parameters of the Plitron PAT-4006-CFB output transformer. To develop the SPICE model (Appendix A3), the center-tapped primary winding with ultra-linear taps is divided into four mutually-coupled segments that have {0.3, 0.2, 0.2, 0.3} of the total number of windings.

LTSpice model for output transformer. 04-24-2015, 01:53 PM. I'm trying to do a SPICE model for the amp I'm building but I have run into a difficulty around the transformers. I have a Hyeboer 18W HT-6135 output transformer. I know the turns ratios an nominal impedance in ohms but SPICE wants the impedance in Henrys.
