Circuit inside DC boost step up pulse power module
Click For Summary
Discussion Overview
The discussion revolves around understanding the internal circuitry of a DC boost step-up pulse generator, specifically a 400kV model purchased online. Participants seek to clarify how the device operates and identify its components, with references to applications such as x-ray scanning.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about the internal circuit of a 400kV DC boost step-up pulse generator, expressing difficulty in finding information online.
- Another participant questions the 400kV specification, suggesting it might be a typo and asks about the application of the device.
- Some participants propose that the device may primarily consist of a transformer, with references to similar products and links to online marketplaces.
- There is a suggestion that the circuit could include components such as a current limiting resistor and a capacitor, akin to a car ignition system, but there is speculation about additional complexity due to the nature of the arc produced.
- One participant mentions the possibility of a pulse width modulator being involved in the operation of the generator.
- Another participant describes the internal components based on an x-ray scan, suggesting the presence of an EHT transformer and components that would form an oscillator and driver for pulsing the transformer’s primary winding.
- Links to external resources are shared for further exploration of similar circuits and schematics.
Areas of Agreement / Disagreement
Participants express uncertainty about the specifications of the device, particularly the 400kV claim, and there is no consensus on the exact internal components or their configuration. Multiple competing views regarding the circuit's design and function remain present.
Contextual Notes
Participants have not reached a definitive conclusion regarding the internal workings of the pulse generator, and assumptions about the specifications and components are not fully resolved. The discussion includes references to various models and potential applications, which may influence interpretations.

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.evan manalu said:And i have x-ray scaning
