Electrical functions are integrated into new vehicles to increase fuel savings, enhance safety and comfort, and reduce CO2 emissions. Much of this is driven by government regulations and advances in semiconductor technology.
The push for CO2 efficiency started with improved combustion and transmission systems. This evolved into smart power distribution systems that delivered energy management on demand. Around the world, new standards require continued reductions in both tailpipe and evaporative emissions. The only way to reach these goals is 100% hybridization of internal combustion engines and, eventually, complete powertrain electrification.
As vehicle electrification continues, designers need to ensure sufficient and efficient power to all high-current devices. Traditional 12V networks now operate in conjunction with 48V systems. Networks include a variety of power electronics, from MOSFETs to IGBT based power modules and embedded power electronic systems. These are used in a wide range of applications: electrical power steering, DC/DC converter, electric air conditioning, liquid heater PTC, electric oil pumps, and start-stop systems up to micro hybrids.
Long term reliability in harsh environments, resistance to vibration, and high ampacity are essential.
