Electric and Hybrid Automobiles


IGBT Power Modules are at the heart of electric and hybrid automobiles.


In Power Drive Systems (hybrid and electric vehicles) IGBT power modules convert DC to AC (battery to motor) and AC to DC (energy from braking to charge the battery).  Power drive system applications include:


  • Hybrid vehicles (cars, trucks)

  • Electric vehicles

  • Fuel cell vehicles

  • Race cars (KERS:  kinetic energy recovery systems)




CPS Product – Summary


CPS manufactures AlSiC baseplates, AlSiC pin fins, AlSiC-pyrolytic graphic baseplates and AlSiC spacers for IGBT power modules.  AlSiC baseplates reduce mechanical stresses associated with differential thermal expansion of module components, thereby increasing module life by as much as 10X.
