Circuit inside DC boost step up pulse power module

[evan manalu]

Any one know circuit inside DC boost step up pulse generator?
I have this one buy from ebay 400Kv type,i want to know how this work by circuit inside..
I had googling and not found result..
Please help me..

400kV? Is that a typo? What is the application?

Just a transformer?

Looks more like 20kV. Still plenty dangerous...

I'd expect it to at least have a current limiting resistor and a capacitor, like a car ignition. But the nature of the arc makes me think there is more.

Right..
More like pulse with modulator..
And i have x-ray scaning
But dificult to identify the component inside

This looks similar

search images for "flyback inverter 400 kv schematic"
You get slightly different results for 40 kv, etc

The large dark silhouette resembles the EHT transformer from a TV: a square ferrite core with the bulges being two separated windings. The other components would form the oscillator and driver to pulse the primary winding of that transformer.
