Itsu can you please test to see if you are getting any feed back current from the snubber circuit back into your PS.

Nick,

as requested, here in green, the current flowing back into the 24V PS from the non dissipative snubber.

See the diagram red square from which point it was taken using my current probe.

The current controller was set to max. meaning 5A/Div.
We see a ± 6A current sine wave with some 5A current spikes during the closing of the MOSFETs (our spikes).

The 24V ps was pulling about 6A of current.

Yellow and blue are the drain signals.

I cannot explain the sine wave current as i was expecting a straight zero line there with some spikes  (the 5A spikes) on it.
Probably my current probe is affected by the yokes strong magnetic field which is very close by.


For what its worth.

Regards Itsu

   Itsu:
   So, it's as I suspected, 5 amps backfiring into the PS output side.
  This current needs to be blocked from returning to the PS. But, just how should this be done?
   I have much higher voltages to worry about, also. With over 200v drain signals and fairly high outputs.
   If reaching the chaotic mode, the current drawn can go much higher, as well.

Nick,

thats the whole purpose of this kind of snubbers, to redirect the voltage / current spike back into the supply so its not wasted.
These spikes (short) are easily being absorbed by the PS capacitors and reused.

   Perhaps you're right. But, I doubt that what happened was a coinsidence, as the PS was working OK until 5 seconds after I turned it on after placing the new snubber circuit on . It seems to be working OK with the laptop adapter on less than 19v. My Kacher does not over heat while running on that voltage, also. Like it does on 24v.
  I'll try to fix the PS later tonight. I have the replacement resistors on hand now.
  Can the caps on the power supply handle 250v spikes? We'll see. But why does Ruslan always place a fat resistor  on the PS where he connects his batteries up to it?

I don't recall seeing protection on those cheapo Chinese PSU's. 

Fat resistor for current limiting.

What is the link for Geofusion's latest video please?
