Abstract :
Short circuit protection can be provided for IGBTs by using a current-sensing scheme. The performance and accuracy of integrated current sensors on IGBTs can be affected by the layout of the sense device. Data is presented on current-sense IGBTs and an improved layout is proposed to increase the accuracy of the sensor
