@Gyula  @All
I am wondering if there is some good way to protect a signal generator in case of using it as driver and not distort the signal, Thanks.

Hi dole,

If I got you correctly you may wish to protect a signal generator's output from being destroyed by any high voltage that might come back from the MOSFETs,  right?   If yes,  than I suggest using MOSFET driver integrated circuits dedicated for directly driving power MOSFETs or IGBTs with fast rise and fall time pulses and if such a driver is destroyed by any HV feedback from the MOSFETs than you have a few $ loss to buy another such driver IC and the generator output is saved.

IF you meant normal distortion because a generator output is not "strong" enough and a circuit justs overload it so that the shape of the signal gets distorted then the solution is also a driver chip like above or a small linear wideband power amplifier stage. 
IS this what you meant?

@Gyulasun
The solution to amplify the signal gen output and to keep it away from back emfs was once given to me by Verpies. Here is the link to that page where he replied to my query.

This cct is only good for non sinusoidal waveforms and thus can be used for pulses.

Best of Luck
Ghazanfar

it's a few days that I follow with great interest the forum and this thread.I want to replicate the circuit, but I have a little doubt about the connection of ground, it is really necessary? I found this page that offers a very simple circuit and an interesting theory about ground connection.

The connection of the ground in the schematics shown in previous pages refer to the circuit simulator ground (common negative) connections and no need for a real waterpipe or buried metal piece ground connection.
There are certain simulator programs that need the usage of at least one ground symbol to run correctly.

This can be a simple analog circuit, directly driving the MOSFETs from one output (the other output remains unconnected).  The supply voltage can be 5V or 5.5V to the multivibrator.  Use a 9V battery because MOSFETs switch ON with less drain-source resistance when driven by 9-10V gate control voltage versus the 5V.

The other possibility is to use the 555 timer IC, google for it, tons of info.

Hi Guyla
Thanks for reply.
I knew already the multivrator but it doesn't permit to set peaks, means not do to PWM.
Thanks for 555timer, Ive found some schematic that I think I can use :)
Cheer.

Dear 0.99
Try removing initial charge from 4700uf Cap. I am attaching the variants of AliGen (v 1.4 and 1.5). The archives include gen's simulation files for Cadence ORCAD 16.3. Here I am also attaching my schematics jpg along with output waveform. It's stable.

Kind Regards
Ghazanfar Ali
Hi Ghazanfar_Ali! And thanks again for your work and breakthroughs  8)
You put in this referred post 2 schematics. Which one I have to replicate and where the load is place please?
And please, where I can find the exact design of the coils L1 & L2?
Cheer.

Hi gyulasun,
Thanks, I thought the same, so it's gonna be CMOS Hex Schmitt

Any thoughts at dispencing with simulations and go for the real thing?

Ali,

I modified my schematic to eliminate the Initial Charge on the capacitor (as you suggested), then ran the circuit for 4 seconds (for complete stability). Shown is the last 100ms of that run.

It's clear from the scope traces of POWER in both the R1 resistor and FG function generator WHERE the power is coming from; in this case, the FG.

I'd like to see your ORCAD version where the circuit is similar to the MS circuit, where the FG is NOT adding energy to the capacitor. Are you able to get that working also and upload it?

Thanks,
.99

the origional circuit without putting the function generator under stress worked with 2 k in series with the frequency source

That's great, but we need to see it operating in ORCAD SPICE this same way. Then I'll be able to sort out where the power is coming from.

@poynt99

Do you believe that ORCAD SPICE provides a more accurate simulation of the real world than Multisim then? I merely downloaded the Multisim 30 day trial https://lumen.ni.com/nicif/us/evalmultisim/content.xhtml as that was the file format being used by Ali. I am wondering whether I should be using ORCAD instead.

Although it is possible Multisim may be simulating the circuit incorrectly, I doubt it is.

I am fairly good at using PSpice and obtaining the required measurements, so that is one reason I'd like to see the ORCAD files with the circuit operating the same as the Multisim. I will be able to get to the meat of the matter very quickly.

Hello all, I'm new here I guess you can say. Been watching this thread and lurking here for awhile now. I think if we are going to use a simulator to test anything we need to run this on multiple simulators to rule out a software anomaly. One thing that worries me is that these results may be a miscalculation by the simulation software. Though similar results are shown between Multisim and OrCAD we should also try other software's (even the free ones) to see if the results are the same or at least still suggesting OU. Each software may use a different calculation method and if multiple calculation methods show possible OU then it's a good chance that the results are accurate or at least telling the truth.

I'll see if I can get a TinaTI sim ready using the latest v1.5 schematic.

Couple of questions from somebody who has always a lot of worries  ::)


1. IRFP260 is the same as IRFP260N ?
2. Assuming that we will choose a circuit for driving mosfets; cold someone explain how that circuit (powered from 9V battery from example) could drive mosfets without grounds of oscillator and proposed circuit merged ? That always bothered me and I still can't get it properly : how to join two circuits : one with flowing large currents at 50V and more and one requiring only 9V and a few mA maybe.Of course we need also to eliminate leakage of power from oscillator to proposed OU circuit.

poynt99,  while it may be good to know where the simulator energy is coming from what actual benefit does this have if  simulator's are not going to simulate tapping radiant energy or energy from other unseen or unknown sources as may be the case with the actual circuit here?
