In this video, I'm presenting my new "Bi-Toroid HV Technology" transformer which consists of a core configured with ferrite U-shaped pieces, as shown in the diagram. The transformer has a central primary coil and two high-voltage secondary coils, developed in house and very well sealed with plastic resin. Each coil has a spark gap at the high-voltage output, and I can also connect gas bulbs for activation. To activate the transformer, I'm using a square wave circuit, the diagram of which is shown below. This is the first test, and it's impressive how well this device works.
