Abstract:
This paper presents an intelligent IGBT module for a quasi-resonant inverter, widely used topology in induction heating (IH) applications. The proposed module is composed of an IGBT and the integrated gate drive circuit which provides dedicated protection function to IH applications: soft start during load detection, long turn-on prevention, hard turn-on disabling, retention of minimum turn-off duration, and overvoltage protection for the IGBT in addition to conventional functions such as abnormal supply voltage protection, temperature monitoring and protection, and fault indication. The module is evaluated in the practical IH cooker to show the effectiveness of protection during the various operating conditions.
