Eric Goodchild and I have built two large twin DRSSTC's. The DRSSTC is a modern type of Tesla Coil that typically uses IGBT's in an "H-Bridge" configuration that switch power into a tank circuit. The H-Bridge is turned on for a few hundred microseconds during each spark event. During this time very large peak currents are created within the tank circuit. (about 1 kiloamp peak for our coils)

	Secondary	12.75 x 45 inches 24 AWG 1/16 inch epoxy coating
	Primary	10 turns 3/8 inch copper tube
	Power Switch	4x CM600HA-24H IGBT brick
	Power Switch configuration	H bridge
	Topload	12 x 45 inch, ring toroid, 7 - 1 inch rings
	Tank Capacitor	14kV 0.57uF MMC made with 2kv 1uF pulse caps
	Bus capacitors	4x CDE 2,700uF 450VDC Inverter grade DC link caps
	Peak Primary Current	1000A peak
	System Frequency	30kHz
	Controller	Steve Ward's UD 2.0
	Gate Drive	Gate Drive Transformer
	Max Spark Length	13 feet
	Bus voltage	680VDC

Chain Mail Suit Project

Eric and I have constructed a chain mail suit which allows the high voltage electricity to hit our body.
