Description

Dual isolated gate driver for Radiant Half Bridge Circuit, designed by "Master Ivo".

Can be used as a impulsed series resonant primary for a Tesla coil, as Nikola Tesla intended it to be.

More info can be found on my channel:https://www.youtube.com/c/masterivo and specifically this video: https://youtu.be/c2_rKc7sHGk (describes this circuit)

Needs symmetrical power supply, and dual channel square wave generator with out of phase 49% duty signals. L1=L2=L3 are all bifilar pancake coils, made from 12,5m X 1.5mm2 or 10m X 2.5mm2 (prefered) speakerwire (pure copper), 10

L1 creates impulses during 1% dead time L2 is series resonant. L2 is the primary, L3 is parallel resonant and is the secondary L1 is close coupled to L3. L3 is loose coupled to L2, L2 is fliiped over (counter wound).
