Hi Magpwr,

yes sure i would be interested, looks very promising that low voltage / amperage input but still with a nice 1kV output.

Thanks,   regards Itsu

hi itsu,

I have just uploaded a crude hd youtube video to demonstrate the 1.1kv nanosecond generator circuit.

The circuit diagram is provided in there.Do check out the test pen lit in free air with nanosecond generator to prove high voltage pulse exist provided with pulse repetition is more than 14.5khz.

I think the cost exceed $100usd for this nanosecond circuit.

Key components
5x kd226d
MUR10150E x 4
APT10035LLL around $13 in ebay
4 or 7KV High Q 1.8pf...2pf and 100pf SMD capacitor *******Expensive ~$32usd ea
IXDI614 (mosfet driver)
35volts Tantalum capacitor for Mosfet driver
Ceramic capacitors for mosfet driver

35volts 33uf x 2 tantalum polymer capacitor connected in series .*Expensive
Can be replaced with single 15uf 63volts tantalum capacitor.

XL6009 voltage boost circuit x 2.
One of XL6009 circuit to be modified(ss34 to ss36 and output capacitor change to 50volts version) to produce tune 47.1volts max to reach just below 1000volts ...mosfet limit at drain.



smd air inductors current rating around 2Amop...3Amps.
90nH
68nH
47nH


------------------------
Tips output of mosfet driver is placed close to mosfet gate.

Start with low nanosecond pulse at the driver while maintaining 47volts for source.

The mosfet needs 23.5volts ..... 24volts to be provided to mosfet driver IXDI614 in order to function efficiently.


R1 can be anything from 60 to 100 ohms.It does effect pulse width to certain extend.Thick film resistor for smd or 1watt 100ohms resistor will do as well.
-----------------------------

The prototype pcb board does look little ugly since there are many small changes.

Thanks Magpwr,

great job, it might be of use for someone especially when you mention it only needs 50V to run with a high repetition rate.

I will stick to my Dally design (modified by verpies) for now.

    I've been working at tuning my set up the last few days. My best running frequency for the induction circuits is now at 25Khz, while lighting 3 100w bulbs.  This is without the full rectification at the output, yet. Only using two UF series diodes in parallel before the bulbs, for now, until I get my 6 amp diodes to make the full bridge rectifier with. Any other diodes heat up.
   When I connect my signal generator to the 0.47uf wima capacitor, the best output at the bulbs is obtained at, also 25Khz. Just like the Mazilli.  However, if I further adjust this frequency to produce the highest output by moving the ferrite pieces in the grenade core, (while running the Mazilli). This normal resonant frequency (25Khz) drops to about 20Khz, instead, and the bulbs get brighter, but, the signal goes into what Itsu calls the "chaotic mode". However, this new resonant frequency (20Khz) produces the best output at the bulbs. 
    I still get NO response from my Kacher/grenade sycronization. This is where I'm stuck at...
As there's something that's just not right about my Kacher's running frequency, not being able to influence the induction circuits to any noticeable extent, while scoping the output, and observing the bulbs lumin levels.

   Itsu:  How are you making out? 

                Keeping in touch,

Nick,

sorry to hear you see no improvements, it is where most of us got stuck.

Itsu:  How are you making out? 

I just yesterday finished building my new nano-pulser so i can swap it out for the kacher.

I like the 1.4Kv pulse, but i am not satisfied with the gate and drain signals which look terrible.
I think when i can clean those up then the pulse will be higher and/or with less input.

Below first screenshot shows the present 1.4kV pulse i got with 260V on the drain, and the second screenshot shows the terrible gate / drain signals.

In this second screenshot, yellow is the drain voltage, green the drain current (500ma/div.) and blue the gate signal.
Pulse repetition frequency was set to 10Khz which causes the input to be 24V @ 1.5A.
When increasing this p.r.f. to the max. 23KHz of the onboard VCO, it increases the input current to 3A.
By the way, this 2e screenshot was taken with the drain voltage set to 130V!
