| Abstract |
This paper introduces an 'IGBT desaturation pulse' which tends to reduce turn-OFF losses for regular and Reverse Conducting IGBTs. Hereby, the effect of the desaturation pulse is compared between conventional IGBT-types and innovative 'low-saturation' IGBT-types with an increased emitter-sided plasma concentration due to injection enhancement. Device simulations for 6.5 kV IGBTs of both types, a gate control scheme to implement the IGBT desaturation pulse into the timing diagram as well as a proposal for a gate-drive unit are elaborated and presented. |
