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