A three-phase Tesla coil
MetadataShow full item record
A special Tesla coil that is fed from the three-phase AC mains power supply is described. Such Tesla coil gives. uniform output voltage in each operating pulse, as it is fed from each phase of the mains with 120 degrees out of phase. There are two versions of such Tesla coil, one with three separate primaries and common secondary, each primary circuit including its primary coil, condenser, and two-electrode spark gaps connected to one phase of the AC mains, and another with only one primary coil, one rotating arm with three two-electrode gaps for each AC mains phase. Both version gives very similar results. The described three-phase Tesla coil is developed as high-frequency, high voltage generator for use in laboratory plasma experiments for research in cleaning of flue gases from SO2 and NOx.
