The Application Advantages of Silicon Nitride Ceramic Substrates in Electric Drive Systems for New Energy Vehicles
It is usually used as the internal support and heat dissipation substrate within the module, directly supporting IGBT or diode chips, and combining with the copper leads or metallization layers in the module packaging to form an “insulated and highly conductive” core structure, thereby ensuring the stable operation of the electric drive system under high power density and harsh environments.
In the electric drive system (motor driver/Inverter) of new energy vehicles, the IGBT power module or power semiconductor module is the core
