Semikron 4 Control pin IGBT
From a drive point of view, an IGBT is very similar to a MOSFET



An IGBT,like a MOSFET is a 3 terminal device. It is controlled via the Gate-Emitter (gate-source for a MOSFET) voltage

To turn on a MOSFET you must raise the GATE voltage with respect to the SOURCE above the threshold voltage. Likewise to turn on an IGBT you must raise the GATE voltage with respect to the EMITTER above the threshold voltage

You are probably used to seeing the SOURCE of a MOSFET ground/earth/0V referenced and thus this key driving requirement appears as just a "gate voltage."

This particular IGBT module you are linking is an inverter leg made from 600V IGBT's.  You will most certainly an isolated driver circuit that is capable of at least 600V+ between the primary &amp; secondary which can also tolerate at 1500V/us dv/dt 

When the voltage between pins4 &amp; 5 (gate and emitter) exceeds 5.5V the left and IGBT will facilitate current flow from terminals 3 to 1 

When the voltage between pins6 &amp; 7 (gate and emitter) exceeds 5.5V the left and IGBT will facilitate current flow from terminals 1 to 2
