• Resumen

  • Purpose – Litz wire manufacturing using mechanical procedures presents several limitations regarding reliability and repeatability, especially when a small strand diameter is used. This paper aims to propose a power supply design for Litz wire manufacturing using a high-frequency high-performance resonant converter.

    Design/methodology/approach – This paper proposes the design of a resonant power supply for induction heating specially designed to tackle with the challenge of heating Litz wires quickly.

    Findings – The proposed converter enables the removal of the isolating coating from the Litz wire through induction heating, improving significantly the manufacturing process.

    Originality/value – The proposed converter improves significantly the manufacturing process of Litz wire through induction heating, with economic and reliability benefits.
