Which is the third model available in LTspice?
There is a third model available in LTspice, the CHAN model, created by John Chan and discussed in a research paper entitled “Nonlinear transformer model for circuit simulation.” The accuracy of this model has been widely proven and it can perform the modelization of the hysteresis loop with only three parameters:
Why do you need LTspice to model inductors?
Inductors are complex and critical components in electronics. LTspice allows designers to make the design cycle easier by providing fast and accurate methods to simulate them. Depending on the complexity of your circuit, you can use one of the three models presented here.
How to make simulations run faster with LTspice?
In order to make simulations run faster, LTspice includes internal models. If you right-click on an inductor, you will see the following window: Here’s a trick for LTspice! If you do not introduce any value for the parallel resistance, LTspice will include a default value.
How to deactivate the parallel resistance In LTspice?
If you do not introduce any value for the parallel resistance, LTspice will include a default value. If you’d like to deactivate this option, go through the Tools menu and select the Control Panel. From here, select the Hacks! tab, as shown below.
How to change the name of a component In LTspice?
(For example, I use c:\\windows emp .) by using the icon, or by typing ‘S’. Change the name of the component in your schematic to match the exact name of the model in the library file. Now when you simulate, your new device model should be used.
How is LTspice used to simulate a transformer?
LTspice simulates the transformer using individual component values, in this case, the inductance of the individual inductors, not the turns ratio of the transformer. The inductance ratio corresponds to the turns ratio as follows: For example, for a 1:3 and 1:2 turns ratios, enter inductance values to produce a one to nine and one to four ratios:
