A CAN Network Architecture for Gate Drivers Dedicated to Wide Band Gap Components

Abstract : In this paper, an innovative communicationnetwork architecture for gate drivers is presented. It is adaptedfor wide band gap gate drivers, particularly SiC MOSFET, in theworking environment of power electronics with high dv/dt of125kV/μs under 1.5kV. In this paper, aspects linked to theconstitution of the entire communication network and itstopology are exposed. The design of the section of the networkthat guarantees the galvanic isolation is detailed. A model of theexposed structure has been established and is described in thispaper. The results obtained through this model are exposed for acarrier frequency band going from 300kHz to 30MHz. The finalchoices concerning the parameters considered in the model arespecified, as well as the carrier frequency. The electronicstructure of the modulator is presented for an application with abit rate equal to 1Mbit/s.
