A compact multi-wire-layered secondary winding for Tesla transformer.

Area of Science:

• Electrical Engineering
• Materials Science
• High Voltage Technology

Background:

• Traditional Tesla transformer secondary windings, known as one-wire-layered (OWL) designs, face limitations in compactness and structural integrity.
• The need for more efficient and robust secondary winding solutions is critical for advancing Tesla transformer performance.

Purpose of the Study:

• To introduce and evaluate a novel compact multi-wire-layered (MWL) secondary winding for Tesla transformers.
• To demonstrate the MWL winding's advantages in terms of size, electrical strength, mechanical strength, and reliability compared to OWL designs.

Main Methods:

• A multi-wire-layered (MWL) secondary winding was designed using a tapered polymeric base tube with concentric-circle and spiral grooves.
• The MWL winding was fabricated with 2000 turns, 3 layers, and a total length of 1.0 m.
• Performance testing was conducted on a Tesla-type pulse generator, evaluating voltage boost, repetition rate, and pulse lifetime.

Main Results:

• The MWL secondary winding achieved a compact form factor, with a length of 2/n of traditional OWL windings.
• The winding demonstrated high electrical strength by precluding surface voids and high mechanical strength due to the polymeric base tube.
• Experiments successfully boosted voltage to 1 MV at a 50 Hz repetition rate with a lifetime exceeding 10^4 pulses.

Conclusions:

• The developed multi-wire-layered (MWL) secondary winding is a feasible and advantageous alternative to traditional one-wire-layered (OWL) designs for Tesla transformers.
• The MWL winding's compact nature, enhanced strength, and reliable high-voltage performance make it suitable for advanced pulse generator applications.
