Hi There
I have simulate a faseshift welding inverter with a LVI coil I did see on the internet.
That do work nicely and now busy with the feedback, I did use a comparator for this and not
the standard UC3875 feedback normally used, I think the comparator way is better for welding
where the output has high short circuit current spikes.
See the sim of this.
and soft switching and stable output.
