Abstract

This article provides a brief description of load conditions for single-shot heat treating, vertical scanning, and brazing and soldering. It discusses the various power components used in power supplies. These include capacitors, integrated power module, transformers, and various switching devices, namely, silicon-controlled rectifiers, insulated-gate bipolar transistors, and metal-oxide semiconductor field-effect transistors. The article also provides information on frequency-multiplication harmonic-induction power supplies, namely, push-pull and half-bridge inverters and full-bridge inverters. Series resonant and parallel resonant circuits and their tuning calculations associated with output networks are also discussed. The article describes the frequency range of simultaneous dual-frequency induction heating power supply, and discusses the advantages, applications, and technical background of independently controlled frequency and power (IFP) induction heating power supply. It concludes with a description of the developments in control systems for modern induction power supplies.
