Design and Fabrication of 3.3 kV IGBTs for Traction Applications

The paper deals with design and fabrication of monolithically integrated over-voltage sensors with 3.3 kV IGBTs for traction applications. The sensor concept is introduced, and experimental validation on 600 V IGBTs is presented. Guidelines for the design of a 3.3kV IGBT including voltage and current sensors are provided together with its process fabrication.
