Control of IGBTs

 

The IGBT drive circuity represents the greatest single influence for operational security in the entire inverter.

The IGBT is a voltage controlled power semiconductor that can be turned with a 15V control Voltage without consuming driving power. This statement often can be found in basic application notes for the use of IGBT and MOSFET components; and few statements are so misleeading.

This and many other aspects are discussed in the download.
