   Well, it may not be long before the VW parked in Akula's back yard turns into a Mercedes.  But, the Germans won't be laughing when they see the Chinese make similar devices to theirs, at 1/4 the price. 
  Won't be long before these gadgets are for sale on the Internet.

I've been telling you for years that _fast rise and fall times_ are the key to getting more voltage from your secondaries. 
-E = dB/dt, after all. Make the rise time small and the voltage goes up. MenOfFather has been telling you the same thing... I think.
Now... pulse width is a similar story. Obviously short pulses must have even shorter rise and fall times. How short is short? The answer is another question: What is your secondary's _resonant frequency_? The stimulating pulse should be no longer than half a cycle of the resonant frequency, otherwise you will be damping the resonant ringing.  If you drive at the resonant frequency, use a 50 percent or less HI duty cycle pulse with as fast rise and fall times as you can manage. If you drive at other frequencies, try to make it an integer multiple (or divisor) of the secondary's resonant frequency, and keep your HI duty cycle short.

Your longitudinal wave is a Standing Wave in the transmission line you have made with the caps and inductors. Your bulb blew out due to VRSWR: voltage rise through Standing Wave Resonance. I think.

Nice work!   

ETA: Everywhere I have "secondary" above, you can just substitute your transmission line.

hi TinselKoala,

This circuit is the most easy to tune in order to get the maximum amplitude.
I started with either low frequency around 1khz to high or high frequency around 250khz base on $$$ component limitation i currently own eg:CREE 1200volts IGBT max :310khz to low frequency.The duty cycle would need to be set at 10%.

Then slowly increase or reduce frequency until the maximum amplitude is achieved.There is maybe more than more than 1 but you just to select the best of the 2 frequency
using the smallest possible duty cycle to achieve the similar or better result.
Another easy way i also noticed the output frequency would be doubled or more than doubled at times at certain resonance.

I have attached a very good video of how a longitudinal wave looks like -
http://www.youtube.com/watch?v=7cDAYFTXq3E

This concept kinda reminded me of the classic ruby rod laser where both end of rod is fitted with relfective mirror but the output is 90% mirror i can't recall fully.
When there is light around rod eg:xenon tube the light will inside the ruby crystal will bound to and fro similar to longitudinal wave.This is how light get amplified
within crystal and throw as laser.

I got this feeling the longitudinal wave get built up "maybe by means of accelerated bouncing to and fro" in my demonstration and reveal as transverse wave\increased amplitude in oscilloscope at resonance.


I think i have made a calculation error during the purchase of mica capacitors.In order to get around 500watt of power we may need to connect around 3 or4mica capacitor
in parallel configuration to get around 0.47uf for one capacitor.In other words  24 mica capacitor is needed for the circuit if 3 mica capacitor to be connected in parallel.

Do not try lower capacitor value 0.22uf which can't handle 500watt bulb even at higher frequency.Tried that earlier in experiment in an attempt to reduce cost.

100uH inductor in the form of toroid or choke would need to be of certain size to handle sufficient current at least 3Amps rated.

-----------------
I have attached my version 3.5 of the longitudinal experiment powered by DC 8.7volts at around or below 8Amp in order to destroy 120volts 2x250watt bulb.T
he lowest possible duty i can logically do is based on my PWM I/C 3525 or 3825 is 3% duty cycle.But i am sticking with 4% for stability base on PWM I/C limitation.

Imagine this 8.7voltsx8Amp=69.6watt(70watt of input power verified with primitive fuse) to just mange  destroy 500watt bulb.


That's COP of 700% of power amplification i can virtually achieve.

8amps Fuse seems to blow once the 500watt  bulb is blown.

If you noticed carefully i am intentionally using 47ohms instead of 5 or 10ohms to igbt so that anyone cannot say that i am getting additional power from the gates.
---------------
Finally i got all the small stuff to fabricate my pcb board-Don smith replication China.

Another busy weekend.

   Magpwr:
   I've had somewhat similar results at times of blowing bulbs when my voltage is too high. Especially when using CFL bulbs, along with incandescent bulbs.
  A brand new CFL 15 watt lasted only one minute before going up in smoke.
   It's probably not that the amps that are too high, but the frequency is not set right.
   Your caps might be providing for too high a voltage for a split second when the bulbs first light up, then dropping down afterwards.
   Please show your actual circuit, with one bulb lit by your device, and the second bulb lit by the grid that is placed next to it. This will show whether you have similar lumin levels on both bulbs, or not.

hi Nickz,

I did a quick test for fun around 4 hours ago using 1  x 120volts 100watt bulb using DC 3volts or 4volts i can't recall which one to destroy 100watt bulb.

There is also a version 4 which i just completed earlier where i use 2 LC(parallel configuration) one from each output of H-Bridge(Left &right)

One of the parallel LC is tuned at 32khz and another LC is tuned at 64khz.The output at bulb is 55khz using 4% duty using DC 8volts 5amps this time(40watt) to power 500watt light.



I tried for fun using tuned parallel LC so that the compressed wave or longitudinal wave won't return back to the H-bridge with another frequency or higher frequency.
This helps to lower current drawn down from 8amps to 5amp only.
I have maxed out this circuit 500watt output/40watt input at 1250% COP.

It's confirmed we can't use mosfet or igbt with built in protection diode for this type of circuit.Only the igbt as shown in screenshot works better.
The options are limited for igbt without diode in virtual circuit.

It's bed time now after 1am Sat.I got to fabricate pcb tomorrow.Time is really short.

  Tektron:
   I just received the two zener diodes that you sent me.  Great!
  They are made by CENTRAL  # CZ5355B.
  I've confirmed that they are the 18v, 5 watt zener diodes.
  Thank you very much.   
   
   I will mount them later tonight, and report back concerning if they made a difference on the mosfet heating issue. I hope so...

   Thanks, again.

   Magpwr: Can't really tell what your problem is with blowing the bulbs. Please at least upload a picture of your circuit. But, it sounds like the frequency levels are not right for those bulbs.
