The values as derived from this application note serve as a base for selecting the most appropriate driver. Semikron s igbt drivers cover the needs to master the challenging conditions of today s power electronics. 8 direct gate drive circuit. Overload and short circuit protection 3.

The gd3100 is an advanced single channel gate driver for igbts sic. An igbt driver turns on and off the igbt very quickly by charging and discharging the small capacitance between the gate and source. The structure of an igbt power mosfet is such that the gate forms a nonlinear capacitor. A new benchmark is set for high switching high voltage application with the skyper 42 lj pv.

The driver achieves gate levels of 40a 6w by using external n type dmos elements for both the gate drive and dc dc converter output stages. It is mostly used when an igbt is run at rated high frequencies like in switch mode power supply smps. The gate is behaving as a memory of the on state of the switch. Ic gate drivers 2 2.
