Ghazanfar Ali Generator - Utlilizing trapped energy

@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

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

Hi Ghazanfar_Ali! And thanks again for your work and breakthroughs 
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.
