(H)EV - Auxiliary
Because overall efficiency is always a primary concern for (H)EVs, it makes sense to consider bringing further substantial loads to the high voltage domain whenever a high voltage rail is available in a car. For instance, EPS (electrical power steering) for which an auxiliary inverter can be used to control the electric motor required. Other common uses: climate compressor, electric charger (eTurbo) and active chassis control.
For these applications and more, discover Infineon’s broad range of dedicated auxiliary inverter solutions. Whatever your (H)EV needs are, we have the know-how and components to realize them to your specifications.
