Short pulse transmission for SiC communicating Gate Driver under high dv/dt

International audienceThis paper presents a new unidirectional data transmission method for gate drivers based ona pulse transformer system. In this work, we focus on pulse transformers integrated on gatedrivers used for aeronautical applications. The integration of communication functions canachieve real time setting of the device for a better flexibility and efficiency. First, an accuratemodel has been developed to simulate the pulse transformer regarding the pulse shape.Then, an experimental circuit was designed to test short pulses transmission through thegalvanic isolation of gate drivers
