48V electrical systems have advantages over current 12V systems, providing 4 times the power and providing greater efficiency when powering fans, pumps, electric power steering racks, and compressors. Higher voltages are more efficient, but automotive regulations demand costly shielded cabling (galvanic isolation) above 60V, so 48V systems keep the cost down. 48V systems used in Mild hybrids, are the cost effective, yet emission reducing first step on the electrification ladder.
48V Electric Supercharger
With the aim of reducing CO2 emissions, turbocharger systems are evolving from exhaust gas driven to electric driven forms for use in Mild Hybrid Electric Vehicles (MHEV). The superchargers improve the response of the engines at low revolutions and
View application 48V Starter Generator
Mild hybrid technology provides a cost-effective solution, for vehicle manufacturers to reduce CO2 emissions and improve fuel efficiency. The starter generator provides electrical power to the 48V network, reducing the load on the ICE and can also pr
View application 48V to 12V Bidirectional DC/DC Converter
In mild hybrid electric vehicles, the DC/DC converter is a mandatory part of the overall system. It is typically used in buck mode to supply electrical energy to the 12V system, which has been created by the 48V starter generator. In some cases, such
View application AEC-Q100 and AEC-Q101 products
ST is able to offer a complete product portfolio including silicon power MOSFETs, protections, gate drivers and microcontrollers, in accordance to AEC-Q100 and AEC-Q101 standards to build cost effective and efficient 48V vehicle networks.
