Go back to:

The schematics in here make use of the libraries presented so far but, while the schematics rely on the custom elements, the thematics are, in general, for power conditioning. There will be no image posted since all the files can be downloaded as a single archive and browsed with LTspice, directly. The links to the file(s) are here.

In no particular order, the schematics are:
Making these examples, even though I had references from anywhere I could find, I used my own way of implementing the schematics in LTspice which, to my knowledge, they are unique, in that there are no other schematics that are built like these. Of course, there may be others related to power conditioning, yes, there may be APFs and UPQCs built in LTspice, but these are my own versions, no plagiarism here.
File-wise, all the schematics have a PC_ in the beginning of the name for easier finding. All the files should be kept as they are, in the directory and file structure as they are now. The symbols and libraries used are, as mentioned, part of the custom models descripted here and they are extracted so that all the schematics inside the folder Power_Conditioning can be run with a fresh, new and clean installation of LTspice. Unfortunately, the inevitable cluttering cannot be avoided; it would have been nice to have .sub and .sym inside the current project's folder in which to store the libraries and symbols, leaving the clean folder for the schematics only. Maybe in future version.
