Hybrid Circuits Simplify IGBT Module Gate Drive

This paper will review the typical gate drive requirements for the latest generation of high power IGBT modules and present simplified implementations of the required circuits using newly developed hybrid integrated circuit (HIC) building blocks. A newly developed circuit that provides short circuit protection without desaturation detection will also be presented.

Trench IGBT failure mechanisms evolution with temperature and gate resistance under various short-circuit conditions

Two extreme configurations under short circuit conditions leading to the punch through Trench IGBT failure under the effect of the temperature and the gate resistance have been studied. By analyzing internal physical parameters, it was highlighted that the elevation of the temperature causes an acceleration of the failure which is due to a thermal runaway phenomenon, whereas the influence of th...

Short-circuit protection for an IGBT with detecting the gate voltage and gate charge

This paper proposes a new short-circuit protection method for an IGBT. The proposed method is characterized by detecting not only gate charge but also gate voltage of the IGBT. This results in a shorter protection time, compared to the previous method that detects only the gate charge. A real-time monitoring system using an FPGA, A/D converters, and a D/A converter is used for the proposed prot...
