Introduction of the driver board based on NOVOSENSE isolated gate driver in the xEV
The main drive electronic control system is an important part of a new energy vehicle. This video will start from the system block diagram of the electronic control system, introduce the components of the system and their functions, and focus on the use of NOVOSENSE's single-channel isolated driver with protection function NSI6611, in the electronic control system: its Miller clamp function can well prevent short circuits; and the DESAT function can shut down IGBT / SiC in time when a short circuit occurs, protecting IGBT / SiC from damage and ensuring safe and stable operation of the system.
