ソリューション

xEV auxiliary systems replace traditional mechanical solutions and improve system efficiency by changing from an engine belt-driven solution to an electric drive solution. Battery electric vehicles (BEVs) do not have a combustion engine, requiring the auxiliary systems to be converted to an electric drive alternative. Hybrids (HEVs) and Plug-in Hybrids (PHEVs) have an internal combustion engine (ICE), but auxiliary systems in these architectures can be more efficient running from the high-voltage battery, rather than the engine belt. While the voltage levels may be different for the design, mild hybrids (MHEVs) have both 12 V and 48 V batteries, allowing larger loads to run from the 48 V power net. This provides benefits from a system efficiency standpoint and can lead to a reduction in wiring size.

In high-voltage systems (BEV, HEV, PHEV) and medium-voltage systems such as MHEV, applications like e-Pump, e-Compressor, e-Cooling Fan, e-Turbo, electronic power steering (EPS), other auxiliary motor inverters, and coolant PTC all address the expanding xEV needs in this space.

onsemi’s automotive products covering Automotive Smart Power Module (ASPM), IGBT, SiC, Super-Junction MOSFET, Automotive Power Module (APM) and gate driver provide the flexibility to design scalable systems that achieve increased power density, lower cost per kilowatt, and superior thermal performance.
