The efficiency of traction inverters at the heart of electric vehicles (EVs) directly impacts the available operating range of the vehicle on a single charge. In addition, efficiency, safety, and reliability are key factors in EV design.
To meet all three requirements, these inverters depend on various smoothly operating components and subsystems, including silicon-carbide (SiC) switches, microcontroller units (MCUs), low-voltage bias supplies, high-voltage bias supplies, DC link active-discharge circuitry, motor position sensors, isolated voltage and current sensors, and isolated gate drivers.
