What is an electrical distribution system?

An electrical electrical distribution system is a series of electrical circuits that delivers power in the proper proportion to homes, commercial businesses and industrial facilities. Regardless of the size and applications, the ultimate goal remains universal: the economic and safe delivery of adequate electric power to electrical equipment.

The Evolution of Low Voltage Power Distribution in Automotive

This distributed power architecture is more efficient due to lower losses in the distribution wiring. Automotive power distribution can also benefit from a distributed power architecture. By locating smaller 400 V/800 V DC-DC converters in defined zones around the vehicle, a simpler and more efficient wiring system is the result (see figure 6).
