Electric Vehicle (EV) Auxiliary Power
Auxiliary power supplies are used in modules for vehicles with some level of electrification on the power train including Mild Hybrid Electric Vehicles (MHEV), Hybrid Electric Vehicles (HEV) and Battery Electric Vehicles (BEV).
The main traction inverter converts DC current provided by the high voltage battery of the car, into AC current required by the induction motor responsible for producing the torque required to propel the vehicle. Performance of this module significantly contributes to the overall efficiency of the vehicle, in terms of its acceleration and driving range. Both conduction and switching losses must be carefully evaluated when selecting the required power electronics components of the inverter module, in order to achieve the vehicle's targeted drivetrain performance.
Electric Vehicle (EV) Charging
With the decarbonization of automobiles and other transportation vehicles, there will be an increasing need for vehicle charging infrastructure. Robust devices and systems, designed for safety and reliability, are needed to power the cars of the future.
48V Starter Generator
Best-in-class Automotive Power Modules (APMs), automotive MOSFETs, and automotive Gate Drivers allow customers to maximize power density, efficiency and reliability for their Belt Starter Generator (BSG) and Integrated Starter Generator (ISG) designs.
Plug-in hybrid/electric vehicles (xEV) include high voltage battery sub-systems, in addition to the 12 V battery. The 12 V battery must be charged from the HV battery using a DC-DC converter, housed in the vehicle. Since these converters are contained in the vehicle itself, they must be efficient and lightweight. The sizing of these units is dependent upon the vehicle’s 12 V power demands.
On Board Charger
Best in class automotive power semiconductors including Silicon Carbide (SiC) MOSFETs, SiC diodes, silicon Super-Junction (SJ) MOSFETs, hybrid IGBTs, and Automotive Power Modules (APMs), enable customers to maximize power density, efficiency and reliability for their On Board Charger (OBC) designs.
