Hi Greg

New here.

Looking at the pdf on the transformer tells me that it is a PF24-24, not PF24-10. PF24-24 gives 24VAC. PF24-10 gives 10VAC (Series connection).
I might be reading it wrong , if so correct me!

And strangely, not a single hit on the word PLASMATRON at wikipedia????

However a google search returns a nice low number of results exposing the work of mainstream academia:

Thanks, magnetO.
Xack, why do you look for a complementary transistor to 2N3055 for Q1 and Q2?
They are not complementary to 2N3055, as they must do different jobs. Q1 and Q2 make oscillations and Q3-Q4 drive the transformer.
I think you can use any medium power pnp transistor for Q1-2, e.g: BD140, BD238, etc.
All the best.

@Kinetix, conclusion

magnetO What is your conclusion after experimented with those diodes?

Hi Kinetix,

you got PM.

Conclusion is, I can possible re-use most of my trashed diodes. Every string has to consist of diodes with nearly same revers resistance.

Best regards

Sorry to confuse...got in a hurry, missed a shift, and bent the brain pan...I'll shut up now and stand in the corner over here so I don't get in your way.

Sk9136?

The complementary PNP for the 2N3055 is MJ2955 according to ST Microelectronics. I looked in Allied electronics and Digikey and I could not find a match for SK9136. Is that a Motorolla number? What's the cross reference numbers on it?

trouble with attachments....

Greg,
Thanks for your response and the information. I finally got my order ready.. or so. I was trying to get the details on the HV Diodes and I could not open up the attachments to the Thread. I found the price between 2000 Volt Diodes and 1000 Volt is a bunch. In your videos your using 2 in parallel. What's the part number and rating. If I could get to the attachments I'd not have to ask you.

Thanks,
Kyle

Sk9136

Here's the specs on that transistor. Looks like it's available.

SK9136
Si PNP Power BJT

V(BR)CEO (V)=100
V(BR)CBO (V)=100
I(C) Abs.(A) Collector Current=30
Absolute Max. Power Diss. (W)=200
h(FE) Min. Static Current Gain=25
@I(C) (A) (Test Condition)=5.0
@V(CE) (V) (Test Condition)=4.0
Package=TO-3
Military=N

That patent I threw at you has some good performance data (look near the end) on that circuit burning gas in a 1977 Pontiac Grand Prix equipped with a 8-cylinder, 301 cubic inch engine.

I interpret the numbers as a 37% increase fuel economy and a 89% decreace in un-burned fuel at the tail pipe.

If nothing else it might be a good example for you guys to compare your performance to.

Sorry if I'm bothering. Tell me to shut up and I'll leave you guys alone. I'm no expert. Just wanted to help that's all.

Oh, don't forget 1420 Mhz

hot

Greg,
What is the power consumption of the "new" bipolar transistor (capactor charger) inverter? .6 amp right? Is that no load or with the car running? You said that your alternator is getting hot. Is that from running the AC inverter or the ocillator/transformer power unit? What's the best set up to start from?

by the way, all you guys, thanks for all your work. I'm on the Allied web site ordering parts to conduct my own set up.

The transformer sounds right, Power out = power in - losses. For a step up, you just apply the voltage to the secondary instead of the primary. If it's designed for 50/60Hz and your driving it with 55Hz you should be well in the ball park.

The problem with popping MOSFET's in 555 type oscillators (Driving the charging circuit) is that they are being driven by a square wave. Two problems exist. 1. they are not being fully switched on as the Source Voltage ~= Gate voltage from the 555 output. 2. the waveform your pushing through the inductor/capacitor components is not sinusoidal. Therefore your pushing the transistor in the top and bottom of the wave to dissipate that power (heat). and in this case without using a "driver" to fully switch it on it gets hot and does not deliver the rated amps. Fully on = Vgs + Vcc. Literally, a sqare peg in a round hole. The bipolars/transformer is a round (sinusoidal) approach. Also, obviously MOSFET's don't do inductive loads without a flywheel diode across the Source and Drain. MOSFET transistors will NOT tolerate non-solid state switching at all. If you use a MOSFET, you must NOT disconnect the transistor circuit from the transformer or inductive load until voltage is 0.

Hi Kyle,

Thank for your interest. With my present 2-transistor inverter/oscillator it draw 5 amps sitting there. The new one that some have been building including myself has a quiescent or standby current of only .6 amps. But the old one draws so much power that I can't (won't) turn on the headlights too. In other words:

-present power hog inverter + headlights = too much for the alternator-

The two schematics we have been working with follow. They are simple, self oscillators ... no 555's or Micros. The first one is the power hog and the second one is looking much better, there is also a capture of the trace from the new NPN inverter @ 45 Watts, input voltage is 14.5 VDC:

The newer inverter really ain't that bad for a simple device.

Thanks,

Greg

currently in service - high quiescent power hog self-oscillator


newer low quiescent power self-oscillator


trace of newer @ 45 Watts load and 14.5 VDC input @ 60 Watts consumption.

[Kinetix]

Greg, please try the trick with that big value capacitor connected with it's "+" at the primary center tap and with it's "-" to ground. Begin with a few hundreds uF, and experiment with bigger values, till the gain stops.
I have seen this on a few oscilators using center tap transformer. It may change the frequency and improve the efficiency.
Best wishes.

tuning

You're right Jetijs,

By tuning the transformer at the right frequency we insure max efficiency.

It's quite possible with this multivibrator type of circuit. Just change the value of the components and that's it. It's not like the inverter type of circuit where the feedback is provided by another winding so you barely cannot change the frequency.

The ideal transformer for our application would certainly be the toroidal, since it's smaller and more efficient at higher frequency.

Also, even if I know that some of us don't really trust them, I would still recommend MOSFET's instead of NPN's for outputs.
They require less heat-sinking, they switch at low resistance and there is no need to overdrive in order to get more power. The result again is more efficiency.

Just my thoughts.


Gibs

Hi Gibs and all,

I couldn't agree more regarding a properly 'tuned' transformer for the job. Knowing this I at least chose a transformer with enough copper and iron in it for my power range. So, I chose a 24 VA (Watt) transformer with a 115VAC Primary and 10VAC secondary w/center tap (configuration). Further I chose a 'semi-toroid' design for efficiency. It is rated for 50/60 Hz. How much more tuned can you get? Problem is ... I'm running it 'backwards' so none of that applies maybe except the size (iron and copper).

If anyone actually KNOWS how to treat this scenario then I'm all ears. There must be a means (equations, analysis, etc.) of determining the proper operating frequency for a transformer of this size (any size) given the configuration and other parameters. I don't know how to do this. If a there was a 'step up' transformer with a center tap on the primary (and was designed and sold as one) then I'm sure it would carry an appropriate rating name plate that could be relied upon.

So, I'm just doing the best I can with what I don't know. I can continue testing with the power hog supply I have but I can't run my head lights too ... alternator get sizzling HOT. The idea is to continue with the Water Spark Plug testing not building power supplies, oscillators, inverts, etc.

Everyone that's built the VexUs circuit has blown CMOS and Micro-based inverters to H--L and back but the plasma circuit survives. TVS's didn't work nor other isolation methods, but the dumb old NPN power transistor-based supply lives on. Just trying to make a more efficient version of the same thing.

Well, there ya' go.

Peace,

Greg
