Quite clearly, the MOSFET body diode is entering its zener region when the MOSFET is OFF. This is due of course to the inductive kickback from the 337uH inductor.

Compare the SPICE IRFP260 MOSFET body diode model with a commercial 1N4989 200V Zener, below:

.MODEL MD D IS=9.22634e-11 RS=0.00602685 N=1.08631 BV=200
+IBV=0.00025 EG=1 XTI=1 TT=0 CJO=5.45582e-09 VJ=2.99908 M=0.9 FC=0.5

.model D1n4989  D(Is=84.5f N=1 Rs=.1 Ikf=0 Xti=3 Eg=1.11 Cjo=2n M=.3333 Vj=.75
+               Fc=.5 Isr=340n Nr=2 Bv=200 Ibv=10.35m Tt=144.3n)

No special "model" is required for zeners in SPICE, they use the "standard diode" model. The model parameters are set according to the diode's characteristics.

@ Mannix and All other friends
 
 Hello Friends
 Here is the ORCAD and MULTISIM Files for my AliGen v 1.4
 I felt that a small pumping of energy is required to keep the 4700 uF charged so why not to connect its one end to the pulse gen instead ground.
 Now u can find it more easy to make the device run without any damping.
 The load resistance I checked at 50 Ohms. And the simulation was still running. To be at safer side I chose 100 Ohms Load. I made it run for 60 seconds on Cadence ORCAD v 16.3 and it ran without damping. A lot of data from Simulation output.
 By increasing Pulse amplitude u will get more energy. Therefore I increased pulse voltage. But it gives good result even with 5Vs.
 Multisim showed me 62 Watts and ORCAD showed 14 W approx with an input of 10 mW.
 Interesting isn't it?
 I am not attaching ORCAD sim files as they are around 42 MB and only its schematic jpg .   Multisim files along with screen captures are as under.
 
 I wish u all the best in your replications.
 
 Kind Regards
 Ghazanfar Ali

@ All
Plz someone guide me what all files with extn are needed for ORCAD as there are so many files in my sim project folder.
Thanks

Is there any way downloading these zip files. Coz every time it gives CRC error.

@forest
So the ingenuity of my mind says if we are getting 149 VDC across the capacitor, why not to use a small amount of that voltage to run the 555 timer based pulse generator of the input stage. ;) That is why I said it can be turned into a 100 % self running generator. The key to start is the initial charge stored in the capacitor C2 or just touch 50V DC source to its electrodes for a while and then replace the DC source. That is how Tariel Kapanadze switches on its KapGen with just a 9V DC battery.
Best of Luck

Ali, can this experiment be replicated with other transistors?   i have  Irf540n   n chanel mosfet -  33 A  100V
i really hope that what ur saying is true and you tried this in real life and works.
and what kind of core material do i have to use for the inductor?

thank you

I havent tested IRF540n.
But I think if it can handle 1000 V at the start for 10 ms then there would be no problem. I just tested it on IRFP260. now I will switch to IRFP264 as it gives more power output.
Kind Regards

Hi Ali,

Perhaps if you run the simulation in Orcad for a very short time only, then the files may have become much smaller?

So then poynt99 or anyone else could use them sooner?

Try to copy some of those files into another directory and open them from there to find out which are the much needed ones?

This forum is optimized for Firefox (Mozilla)  perhaps this the problem when downloading with other type of browsers.

Thanks for the tip gyulasun. Downloading the zip files via Firefox does indeed resolve the problem seen with IE9, IE10 and Chrome.


I'll continue to provide an archive of the zip files at http://tinyurl.com/7pzrv7p for those who continue to struggle.

I would not be so optimist.Clearly the zener-like structure in IRFP26x series match with circuit parameters, but what and why is to be resolved. Then almost any mosfet can be used with proper zener instead of build-in. Just my two cents. ;D I think that Ismael Aviso could help us here if he was willing to do so....

There are some sizable differences between the IRFP260 and IRFP264 mostly in rise and fall times.  How important might these differences be?  Probably just need to test to find out but :
IRFP260:
Drain-Source Breakdown Voltage:    200 V    
Continuous Drain Current: 46 A
Fall Time: 28 ns    
Power Dissipation:  280 W    
Rise Time: 30 ns    
Typical Turn-Off Delay Time:  90 ns


IRFP 264:
Drain-Source Breakdown Voltage:    250 V    
Continuous Drain Current: 38 A
Fall Time:  92 ns    
Power Dissipation: 280 W    
Rise Time: 99 ns    
Typical Turn-Off Delay Time: 110 ns
