The lower conduction and switching losses allow a significant improvement in efficiency, especially at higher temperatures, and the use of smaller and lower-cost components in power-control circuits. In addition, the IGBTs’ compact industry-standard TO-247 package saves component count by also integrating an ultra fast freewheeling diode. The 1200 V IGBTs also feature a short circuit withstand time of 10 µs, making them resistant to common causes of motor-controller failures, such as an error in the gate drive signal, shorting at grounding, and breakdown of motor phase-to-phase insulation.
