Abstract

A single-sided induction heating system based on IGBT is proposed. The system includes the series resonant circuit, control circuit, and auxiliary circuit. The main circuit includes rectifier, filter, inverter, and resonant circuit. A drive circuit is designed for IGBT combing some protection circuits. We have a simulation of the single-sided induction heating system in ANSYS. The simulation results are compared with the experimental results. The performance of the system is promising. And also we estimate the temperature distribution model by the least squares theory.

Highlights

  • The electromagnetic induction heating technology, which is known as the “green heat” mode, is increasingly being used in areas of industrial production and civil applications, such as industrial electronic encapsulation, surface quenching, melting technology, civil induction cooker, and water heater, due to its high efficiency, security, and other significant advantages [1]

  • The values of inductance, capacitance, and resistance in the inverter circuit can be determined according to actual measurements and calculation

  • Temperature measurement instruments are the handheld infrared thermometer made by Fluke company

Summary

Introduction

The electromagnetic induction heating technology, which is known as the “green heat” mode, is increasingly being used in areas of industrial production and civil applications, such as industrial electronic encapsulation, surface quenching, melting technology, civil induction cooker, and water heater, due to its high efficiency, security, and other significant advantages [1]. Induction heating power is a kind of inverter device which converts alternating current power to the middle frequency alternating current, high frequency, or ultrasonic frequency alternating current by electromagnetic induction principle to change electrical energy into heat energy [2]. It has the characteristics of achieving automatic control, the short heating time, and high temperature [3]. This paper introduced the design of IGBT induction heating equipment which was used on the single surface. We introduce the principle of single induction heating. We do some simulations and experiments and have a conclusion
