Abstract

Abstract : 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.
