CCM3 Simulation

Hello,

I'm trying to simulate the Flyback Converter in LTSpice for 10.4c. I've read on a different posts to use CCM3 from the switch.lib. CCM3 allows you to set a 1:n turns ratio, but how do I set up a magnetizing inductance? I found a way to create a transformer on LTSpice by coupling two inductors and using a SPICE directive called K-statement and setting the n = 1 in the CCM3 model. Would this approach work or does anyone know how to add Lm to CCM3?

Thanks for the help!

    Claire,
    There is a transformer model included in switch.lib that has turns ratio and Lm parameters. Also, there is a transformer symbol (save as .asy) file available on the assignments HW 4 web page.
