Automotive supplier Schaeffler has started mass production of a new high-voltage inverter brick equipped with ROHM’s silicon-carbide (SiC) MOSFET bare chips as part of its strategic partnership. The inverter assembly, also called a “brick,” is the core power building block that controls the electric motor using logic signals. The traction inverter acts as the bridge between the high-voltage battery and motor. Its primary function is to convert DC from the battery pack into AC used to control the motor’s speed, torque, and other characteristics. By integrating SiC MOSFETs, the frame-mounted sub-module can fit into a compact form factor with high power density.
