As the ZPM thread has so much content that it started to load slowly especially on mobile devices, I'm creating a new thread continuing the initial thread.

If you want to search for specific information posted in the initial thread you can find it here:

 

Romanian ZPM (Zero Point Module)

 

In this initial post I'm also adding the donation section as I did in the initial thread:

If you find ZPM intriguing and the experiments and data I share here with you useful for your own projects and research, you may help the further research by donating:

 

 

Your support will be very much appreciated and it will be used ONLY for equipment and building customized electronics for further research and experiments.

If you're working with a ZPM replication please share your findings here like I do so we can enhance this device.

Thank you,
Fighter

Another UA7812 voltage regulator from the MOSFET driver smoked:

So I decided to get rid of this approach with voltage regulator for powering the switch LED, now that LED is powered by the separate power used for cooling fans and switched on or off by the main switch. Those switches have two set of contacts so when switch is turned on it can close two separate circuits.

Another thing I did was to put high-voltage super-fast SF28G diodes on the MOSFETs but I had some problems with this, when exploring with different frequencies few times I had sudden surges of the power drained from the DC source, the source entered in auto-protection and the 12V/55W light-bulbs from ZPM's output became extremely bright and were destroyed. So far I lost 3 light-bulbs of that type, I have only one left which is still functioning (link to larger image here):

For some reason seems ZPM doesn't like those protection diodes and at certain frequencies it suddenly starts draining full power from the DC source and smoking the 12V/55W light-bulbs.

For now I have set optimum frequency and the 12V/55W light-bulb seems to work fine but probably as soon as I will encounter one of those frequencies the same thing will happen again. If it happens probably I'll remove these protection diodes, I don't like this behavior and it's provoking damages, I don't know what's the reason but it's a fact.

You need to limit the current using a resistor to 10-20 mA, whatever your LED needs. 12v / R = 0.01A.

It's okay, now I removed that voltage regulator and both LED's are powered by the separate circuit powering the cooling fans. I suppose that voltage regulator didn't liked the pulses present on DC source's input, it expected clear DC voltage there.

Fighter.

Because the bulb is constantly getting damaged. Perhaps it would be better to use a wire resistor in this form. Or it would be better to use a heating element. This way, the energy of the heat could already be measured. This measurement method is also recommended by Robert Adams. Temperature of water heated per unit time.
Disassembled old appliance heater
(if someone is trashed):
sandwich oven has two 110V heaters
water heater 220V

In my opinion, FET overheating is caused by the load current (12V55W bulb).
You can see it here.

ambient temperature is 20.6 ° C
The drive is FET 22.5 ° C
Bulb switch FET 44 ° C

Sorry but that's an abnormal situation, not only the light-bulbs are destroyed but the DC source enters in auto-protection mode.

Is nothing to measure in that situation, I intend to avoid it as it could destroy my equipment...

Finally found some time to check the PowerSource, I verified IRFZ46N's drain-source continuity and found they were shorted so the MOSFET was damaged by that malfunctional DC adapter.

After I removed the MOSFET I checked that the circuit where its gate pin was is still receiving square wave signal:

 

As you can see the square wave was present so I mounted a new IRFZ46N. I must admit I had some big concerns as my soldering tool is not that delicate for this kind of fine/small circuits so few times I was thinking the copper areas where the MOSFET was soldered will be destroyed by the heat of my tool. There was a high risk of damaging the circuits from the MOSFET area...

After I finished I've made a test with the PowerSource module powering up a PowerSwitch module driven by my signal generator. Wanted to make sure the repair succeeded:

 

So now the PowerSource module is functional again but I don't intend to use again a cheap DC adapter, I bought a 12V/2A AC transformer and a big 4700uF electrolytic capacitor and using one of the bridge rectifiers I already have I'll build a dedicated DC adapter:

Of course I'll build it when I'll find some time again...

Just a short post, a few days ago somebody asked me through email what's under that red tape covering the middle of the Metglas, if there is a gap and if it's something in it which I don't show:

There is no gap or something secret there, I did put that red tape when I first built the ZPM in order to to keep as close as possible the both pieces of the Metglas core together. To have everything crystal-clear I removed that red tape and used a strong plastic zip tie to continue keeping the pieces of the Meglas core together (link to larger image here):

All the information about ZPM is public, complete and published in this forum. And will always be this way.

It will be updated as I continue the research depending on the free time I can find.

Thanks,

Fighter

Hey Fighter, while it is very nice of you to show that there is no secret sauce hiding under the tape I would urge not to get distracted with changes to convince people. I take you at your word that the device is exactly as you describe it. Do what you think is good, but you don't need to appease or convince the naysayers IMO.

My Friends,

Hahahaha Yes, I agree with Zanzal!

"Whats under the tape", hahaha a 26 Plate Lead Acid Battery?

Apologies, they say: "Sarcasm is a metric for potential - Howard Stark"?

I agree, sweep the silly aside!

Hahaha, the joke about the battery made me laugh after a hard day at work, thank you Chris !

I don't know who the guy is but most probably he was thinking about some permanent magnets or God knows what kind of "secret" thing hiding under that red tape.... Well, I think he didn't expected me to reveal the "secret", I may disappointed him, I apologize for this...

lols yes, although it must be said. i dont see any nay-sayers.  more like kids in a candy store

I've build the customized DC source for the PowerSource from Vidura, I tried to make it as compact as possible (link to larger image here):

I put the bridge rectifier directly on the transformer's core so the core can be used as a radiator if the bridge rectifier becomes warm.

But there are two problems with it:

  • the 4700uF/100V electrolytic capacitor seems it's not doing its job very well, I have a 620mV Vpp, the capacitor is brand-new;
  • the output is not 12V as I expected, it's about 16V.

(link to larger image here)

The transformer is 230V/12V and also brand-new (link to larger image here):

@Vidura, I suppose this is not acceptable for powering up the PowerSource, isn't ?..

About voltage I suppose I could put a resistor on output for lowering those 16V to 12-15V but I'm not sure what electrolytic capacitor I should use in order to have a linear DC.

I need to check on the scope the output of the 12V secondary, maybe the factory put more turns on it and it's actually 16V there...

Vidura posted this 8 hours ago

Hi Fighter, This voltage is normal when it is rectified and a capacitor connected. The rated transformer voltage is RMS , and so the output rectified and filtered will unloaded output the peak voltage. Anyway 16 volt should be ok, the driver IC is rated up to 18v if the resistors of the snubber circuit becomes hot you can lower the duty cycle on the preset of the module. Regards Vidura.

Vidura posted this 8 hours ago

I suppose that the scope trace is the ripple, 620mv is no problem at all , it is filtered again in the module , and the final stage, the power switch modules have a filtered voltage regulator, there will be pure DC always.

Fighter posted this 8 hours ago

So this output is acceptable for PowerSource. Then next when I find some time I will start tests with ZPM.

Thanks for clarifications Vidura, I really appreciate your help...
