Circuit inside DC boost step up pulse power module
Click For Summary
SUMMARY
The discussion centers on the internal circuitry of a DC boost step-up pulse generator, specifically a 400kV model purchased from eBay. Participants question the voltage rating, suggesting it is likely closer to 20kV, and discuss its components, including a current limiting resistor, capacitor, and potential pulse width modulation. The circuit is compared to a flyback inverter, with references to high-voltage transformer schematics and components typically found in ignition systems.
PREREQUISITES- Understanding of high-voltage circuits and safety precautions
- Familiarity with pulse width modulation (PWM) techniques
- Knowledge of flyback inverter design and operation
- Experience with electronic component identification and schematic reading
- Research "flyback inverter 400kV schematic" for detailed circuit designs
- Study the operation of pulse width modulation in high-voltage applications
- Explore safety measures for working with high-voltage circuits
- Investigate the components of ignition systems in automotive applications
Electronics enthusiasts, engineers working with high-voltage systems, and individuals interested in the design and operation of pulse generators and inverters.

400kV? Is that a typo? What is the application?evan manalu said:

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
