Hello there everyone !! I am prabhat and I come from India. I am a first year electronics engineering student who has great interest in this field but I know very little . I am trying to learn a lot of things from places like YouTube and Google and also tried building some small projects . I have had built a small 100 watt induction heater which works quite well. The latest one being the sstc 3 from kaizer site itself. And i have opened 2 threads regarding the same out of which one is completely resolved . I had passion for this field for a long time but due to lack of theory knowledge in this field I get stuck many a times and thats when I need this forum's members help. My best wishes with everyone during this covid  -19 outbreak
 Stay safe !!

Hello - my name is Rob. I've been designing custom analog bipolar and CMOS integrated circuits for 28 years. I've done chips for everything from military to toy trains to medical equipment. DC to GHz. I now live in Montana (USA) and work as a consultant. 

 The high voltage world is a total departure for me. None of my chips have ever exceed 500 mW. Most are less than 1 mW.  I have very little experience with power electronics like IGBTs or even discrete components. 
 
Four years ago my son, who was 13 at the time, saw Electroboom's Tesla Coil and wanted to build his own. While we could duplicate Medhi's poor results, we wanted more. My son actually gave a lot of good ideas that advanced us to where  we got much stronger arcs but had a problem blowing up transistors.  As an aside, it turns out that you can be a very well respected electrical engineer for nearly thirty years, but if you smoke up the house *just once* your wife makes you work with a fire extinguisher by your side. I tell her I now put fuses in all power lines, but she is still tense when I'm working on this. 

Covid-19 has given me time to resurrect the project. Although I do now have a single transistor design that can produce 10" arcs reliably, I still blow a lot up trying to improve the performance. I wish I learned about TVS diodes before last week and saved a lot of transistors...

Welcome Prabhat
as an engineer hopeful you have much to learn
you learn from your own mistakes ie working out what went wrong and doing it again with that mistake fixed and now looking for the next one.
you do learn a little from others mistakes, but your own are where the most learning comes from
Go out and experiment if you do not understand why it went wrong document fully and put it up here on this site, --the brains trust is sure to help

enjoy

Hello all, well I just read thru all the "Welcome new members " posts and have now understood why 4hv hasn't
replied to my registration, a few of them are here!! 8) To start with, I am 56 yo service tech for Phenix Technologies in Maryland. We manufacture High Voltage, High Current, High Power test equipment and components. Started learning about electronics about 9 yrs old, spent a lot of time at Radio Shack and reading their books, then more formal study in high school. Went into the military and got more formal study at TOFTOY
at Redstone Arsenal Huntsville, AL. My MOS was 27E, TOW/Dragon missile guidance technician. After military
I went to College and got my Associate Degree in electronics. My passion is HV and working on a frankenstein
SSTC that is mix of Steve Wards SSTC-5 and a few others. As I mentioned I am a service tech, I travel a great
deal around the world, and COVID has put that to a halt. So lots of time to get frankenstein spitting lots of PD  ;D. I hope to learn more from you guys and contribute to this forum. It's great to be here!

Hi Rowdy and welcome to HVF!

Great resume and I hope you will feel welcome and get all the help you need, looking forward to see a project thread about your SSTC.

Phenix seems to be in a great variance of fields, any specific you work in as service technician?

I would like one of these, if you happen to have one at work that is just collecting dust and is to be thrown out :D https://www.phenixtech.com/Files/Admin/PDF/40302_Ultra_HV_DC_Test_Systems.pdf

Hey Mads, LOL no we do not have one of those in the scrap pile, customers tend to have those fixed. Lots of money in one of those units. Actually I service and calibrate everything we make.
