48 Volt Technology: Development & Drivers …

48 Volt Technology: Development & Drivers

In the early 1990’s there was a lot of excitement around the introduction of a 42V power supply. Due to the high cost of components and the lack of a real driving force for development this system was ultimately unsuccessful.

In today’s market components are much cheaper, technology has improved considerably, and the need to reduce CO2 emissions is a substantial driver for the concept of 48V. The challenge for OEM’s and suppliers is now to create an inexpensive alternative to hybrid vehicles, which will provide a significant reduction in CO2.
