Evaluations of 4th generation IGBT for Induction-heating Voltage-fed Single-ended Inverter

Abstract

Voltage fed single-ended resonant-type inverters are commonly used for induction-heating cookers because of their relatively small device switching losses, low cost and compactness.
This paper presents a performance evaluation of the 4th generation IGBT when used in voltage-fed single-ended inverter for induction-heating cookers as the switching device.
A total loss reduction of 11% was observed with the 4th generation IGBT as compared with the 3rd generation one. Moreover, its chip size could be successfully made smaller by the approach or increasing the current density.
