8 H charging choke request

Post by Joshua Guertler » Mon Jul 01, 2019 10:14 pm

Greetings,

Would any one happen to have an 8 henry charging choke that can handle 10 kV and 100 mA?

If not, would anyone happen to have any pure steel (99.8% or 99.95% pure) rods with a diameter greater than 6 inches and a length equal to or greater than 2 inches? Thank you.

Sincerely,
Joshua Guertler

Joshua,

No need necessarily for a massive charging choke for your system at all. I would just use some decent wattage high voltage charging resistors to limit current, as well as a suitable HV diode for protection, which can easily be found at the voltage and current levels you are after quite cheap on ebay. This will probably be smaller, cheaper, and much more manageable to handle. However, if you still really wanted to make a large charging choke, you can always use a bundle of smaller diameter iron rods coupled with many turns instead of one giant piece, which would be extremely heavy and expensive.
