It has been a while that I wanted to remove epoxy from one of these HV module which are sold as 400 kV devices. Even though I knew the internal circuitry to some extent, but i wanted to know it exactly and also I wanted to know clearly how to remove epoxy from a potted electronic circuit.
This video took a large amount of effort, and I have learned quite a few new things. hope you enjoy.
A functioning and clear procedure of epoxy removal using Acetone is presented. the schematics of this 400 kV module is shown. To my surprise the device after being removed from the epoxy was still functioning and so I could get the input waveform and measure the frequency of the oscillation. At the end I created a Matlab Simulink model for this device, and different possible failure modes of the device is discussed.
The last few weeks very super busy, working in the lab with Philip, reading many master theses and participating in the MSc defenses forced me out of KZfaq for a few weeks. But here I am back.
Deeksha and Philip defended their thesis last week, so congratulations to both of you. Deeksha thesis has open a new line of research about transformer magnetic modeling. I am curious to expand my knowledge on the topic. Philip did an excellent job and demonstrated a hardworking and skilled student. Many days we had to work till late night to get the data and design a functioning pulse transformer. Thanks Philip and Deeksha for delivering a good work and for being ta motivation for me to learn new things.
Even after not producing videos for nearly a month still i am ahead than what i promised to myself.

Hello, absolutely this generator does not generate 400 kV, no way.

This is the most comprehensive break down and explanation of one of these units that I have ever seen. A brilliant bit of work, thank you very much.

Start counting from ZERO - not one :)

That's not a "voltage tripler" circuit at the end of the circuit. It's a voltage doubler, with a half wave rectifier diode, and the large capacitors, to change the output from A.C. to D.C.

400 Thousand Volts.😂😂😂😂🤣😂🤣🤣🤣😂🤣🤣🤣😂

Great analysis. One important detail: the output transformer has 6 windings in series. It is critical in this type of high voltage range. If there was only one winding with 6 time more turns, assuredly, the transformer would internally produce arcing and would burn very quickly. Hence, the importance of using 6 isolated windings in series, as is the case here. Great video, thanks, I wanted to open one of those for a long time. 🎉

These modules are sold on eBay among others as "high voltage modules". But in fact it's the business part of stun-guns.

@Freddyfanmulti3214

the driver looks like it survived a war

@bl4cklainer35

is it possible to obtain the simulink model

@MikeOxolong

Is this high voltage module dangeours? It is 400 KV, so I assume you will get a shock, but if the input is 5A at 6V, the output current should be something like 0.3 uA.

Awsome. For years I was wondering what was inside one of these. 👍

A great video: You don´t simply explain everything, you also lay out the whole methodology for researching a circuit, and even that is a win, for anyone with zero interest in this concrete circuit... But would you please upload also in 480p in the future, cause I´ve noticed that with time, less people do that, (usually just 360p and 720p), but I find the 480p still to be the most practical !!! I use a microcomputer (like a growng amount of people also do), and for my relatively huge 80cm-screen, 480p still has the best looks, while not going hard on the PC (480p isn´t high enough for football, but people using microcomputers, will watch much more videos like yours, than watch football anyway)...

You were actually counting fast. 😂

Thank you for this valuable video.

@suryapratap_tech

Very good explanation and the way of breaking down was also good, with some precautions, you could have gotten a perfect internal circuit. But it was very amazing, I liked to learn many things about that generator.
