Title: Shove Yank Parallel
Post by: KD6VXI on May 03, 2016, 10:52:38 PM
 OK,  have a single ended class E one transistor amp functioning.   

Want double the power.   Eventually more,  but this is the next step:

Would I be correct in approximating push pull parallel as having a binocular core xformer from drain to drain,  with the output network after that?   I realize the core would be bigger than a standard binocular,  but ya get the gist.

If not,  what am I missing.

Thanks,  in advance.

I haven't had tremendous luck with traditional push pull and class E.  I have had very good success with single ended push-pull.  The single ended push pull approach scales VERY well, and you can parallel up MOSFETs for each of the single ended push-pull "modules", and then run the secondaries of the output transformers in series.

This may be the approach to take.  The harmonic suppression is also excellent.
