  That was the same Tl 494 board on Ebay, for $7, or so, that Itsu used to do some tests on. He mentioned previously that that TL 494 board has to connect first to mosfet drivers, and also, the mosfets need an adequate snubber circuit for the TL board to function properly.
  I think that he made a video of it, and suggested that I try it out, as well. Which I think that I'm about to embark on, myself.
  Maybe he can post a link to that video, as I can't find his videos on YouTube.

Good to hear that you are going for a PWM. Magpwr's design looks robust and quite easy to build.

  Ok, thanks for that info, again.  I wish that you had stayed with it, instead of moving on...
  It looks like your 100w bulb is not lit to more than 50w output or so. Is this the case? And how many of those bulbs could be lit?
  You mentioned that the duty cycle was not able to be controlled on that board. No duty cycle then?
 
   Remember when I asked you about making a Kacher driver using the IRFP260N fets, and the TL 494 board? 
So, that the Kacher frequency/duty cycle can be controlled also.  Check this out. Looks like it has plenty of pep...
