Hi Terry,They're fairly straightforward coils, secondary form is 24"x105", toroid is 11"x55". These dimensions are 1:12 scale of the 12-story NLL design. These prototype coils are used mainly to test design concepts for the NLL coils. The primary drive is the conventional C-switch-L scheme, with IGBT's in place of a spark gap for improved efficiency and control. The primary operates at 3kV, 4.5kA. Currently, the system can produce an 18ft point-to-point arc with about 6kW input power. Although the prototype operates from either single or three-phase power for convenience of demonstration, the final NLL design will use a dedicated six-phase, 20kV system. GL
