Abstract:
Currently, the gate driver unit for power semiconductors provides the control of the components and ensures the safety of the switching cell. The integration of a communication function on a driver is described in this article. This new function sets up a communication channel between the primary side and the two control channels of the driver that are located on the secondary sides. The communication is done by using the CAN protocol. This paper introduces an innovative solution to provide a galvanic insulation to a CAN bus that fits the specific requirements of power electronics, especially a low parasitic capacity primary - secondary and the immunity to high dv/dt. A first prototype was designed and the experimental results are exposed. This project is a joint effort between the IETR laboratory and ECA Group Company
