   Hoppy:
  I'll keep it in mind.
  Such as:
  http://www.littelfuse.com/products/tvs-diodes/leaded/1_5ke.aspx#

   I'm still wondering why Itsu's snubber resistors aren't heating up.
   I'll see if I can order some bigger 3w carbon resistors, as I'm not sure what type the ones that I have on are. They are the resistors I showed in the picture. The 1/2 watt didn't make the grade. Nor the present 3 watt ones, either.
   But, first I'll disconnect the Oleg snubber and see if the Fets snubbers calm down.

   I removed the 3 watt resistors and reconnected just the snubber caps. Using 3 200w bulbs on as the load, I get 230 volt peeks. And some ringing back. FETs getting warm but not hot. Oleg snubber makes very little difference in bringing down the peaks. But I'll leave it on for now. Probably need the right type of 1K resistor there also.
   At least those previous 3watt 56 ohm resistors are not there getting hot. As they are not installed any more. They're probably not the right type, either.
   Possibly some of the ringing on the flat top part of the squares wave is good. I still have to work on getting those 200 + volts peaks down some more though.
   I got the 50 volts back on the square wave, while the running frequency is around 16.6KHz. The three 200 watt bulbs are fairly well lit, considering it being a 600w load.
  No interaction from the Kacher, as yet. Kacher running at 1MHz to 1.1MHz. Ferrite inside the Kacher does not help too much in varing the running frequency, nor increasing the brightness of the bulbs

Hi all, I was looking through some of my snap shots and came across a couple of snapshots, I was wondering if any one wanted to compare any of their snap shots assuming you get my drift in that area.

Am I being vague and confusing oh surely not Oh dear where have I gone wrong?
Do you think the wave distortion is due to a detune in the wave length somewhere?

Ile leave you with that one.

Nick,

removing the 3W R from the RC snubber and thus only leaving the C connected means you have removed the snubber, as a C alone across the drain / source can hardly
be called a snubber, it just adds capacitance to the MOSFETS drain / source capacitance.


If the Oleg snubber has no effect, i would remove it.    I think you could be right about the 1K resistor of the correct type there.  It could make a difference
including a high quality cap.

50V square waves when driving it with 24V is to be expected, so that looks good.

I would try to find the correct resistors for the RC snubbers and go for the TVS option.   I think Hoppy mentioned something like 140V clamping voltage.


Can you see any interaction on the inductor or wima cap sine wave signal when activating the kacher?  (be aware you might have some 500 or so volt there).

Thanks very much for all the answers.
I will try to first understand more and than step by step build something.  ( in the past  i didn`t experiment so much yet with ic`s ... so  now is the time )
I learned a lot allready from the things I read on the last pages  and  i will flip back to previous pages also  .

I am enthousiast       Yeahhh !       (  like to become a Genius ...  ehmmm  a  technical Genius  : )
