LTspice has a way to model electromechanical switches, which I have occasionally tried to use to simulate dc-dc converters without all the hassle of setting up mosfets and appropriate driver circuits.

We always enjoy [FesZ’s] videos, and his latest about FREQ function in LTSpice is no exception. In fact, LTSpice doesn’t document it, but it is part of the underlying Spice system. So, of course, you ...

We always enjoy videos from [FesZ], so when we saw his latest about tips and tricks for LTSpice, we decided to put the 20 minutes in to watch it. But we noticed in the text that he has an entire ...
