Improved Litz wire manufacture process using resonant power converter-based induction heating

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.
