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 Youtube 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.
