Circuit:


Before coupling:

The Resonant circuit looks good.


The gates look good.


After coupling:

The capacitor’s current is stuck at 0A.


The gates aren't alternating.

 

hi dylan,
Welcome to AAC.
Try this version of your asc, note V2 o/c.
The biassing was incorrect.
Also use the 'Alternate' option in the Control Panel.

Thank you Eric,
What I understood from your answer is:
1. The current was not alternating because the biassing was incorrect.
2. The biassing was incorrect because of voltage source 2.
If the above is correct, could you explain how voltage source 2 affected the biassing, and what "o/c" means?

 

hi dylan.
Check this recent thread on a ZVS osc.
