8000FPS Slow Motion Tesla Coil Spark Formation and Collapsing Hot Spots

Slow motion Tesla Coil recordings of SSTC sparks. Recorded at 8000 frames per second and replayed at 15-30 frames per second. Notice the step leader, known from natural lightning strikes and the hot spots that might be forming from collapsing plasma channels. Join the discussion at High Voltage Forum about these high speed video recordings …

Where To Get “Free” TO-247 IGBTs and MOSFETs

A look at a box of IGBTs and MOSFETs that I have salvaged from household electronics like microwave ovens, induction stoves, solar inverters, welding machines, car and battery charges and other common high power electronics with switching inverters. The TO-247 IGBTs can be used in a DRSSTC Tesla Coil using the free half- and full-bridge …

Project Documentation: Tesla Coil Soft Start Safety Box

The Tesla coil Soft Start Safety Box project has been finished. The first version of my soft start box for 3 phased 400 VAC loads was just that, a soft start box. I wanted to include safety features like fault detection and emergency stop, but I also wanted to remain galvanically isolated from the mains …
