A survey on high-frequency inverter and their power control techniques for induction heating applications

Abstract

Intensive use of induction heating (IH) technology can be seen in many areas such as industrial, domestic and medical applications. The evolution of high-frequency switches has facilitated the design of high-frequency inverters, the key element of induction heating technology. Controling output power in a high-frequency inverter for induction heating application is complex. However, the importance of IH technology is not widespread. Induction heating technology requires accurate output power and current control with appropriate dynamics. Several power control techniques have been discussed inrelation to designing high-frequency inverters for IH applications. This paper makes a comprehensive review of the various power control techniques regarding high-frequency inverters for modern IH applications (domestic & industrial).
