Picture

Torque vectoring (TV) power electronics

Three-phase permanent-magnet synchronous machine (PMSM)
The power electronics of the TV motor transforming the direct current per two parallel-switched Easy Pack IGBT modules made by Infineon into alternating current of variable frequency and voltage, carries up to a 70 A peak phase current even in case of a motor standstill.
