Abstract :
Self-clamped Inductive Switching (SCIS) energy capability is a critical parameter of device performance for IGBTs used in automotive ignition applications. In this paper, we studied a monolithic dual-voltage self-clamped IGBT to improve its SCIS energy capability. During an inductive turnoff process, the collector voltage of the proposed device is clamped first at a high level for a short period of time and then at a much lower level until the electromagnetic energy stored in the inductive coil is fully discharged. The concept has been verified and analyzed with extensive numerical device simulation. A monolithic prototype device has been designed and fabricated with a conventional eight-mask IGBT process. The experimental results are reported
