English Abstract

This paper presents a study on the gate driver circuitries that need to be implemented to drive several power devices when associated in series connection. More specifically, the propagation paths of parasitic currents through the gate driver circuitries, exited under high switching speeds, are studied in different configurations trying to minimize common mode currents generated. In a gate driver ...
