Summary:

OEM's and car manufacturers suppliers have agreed to increase the electrical system operation voltage up to 42VDC -36VDC battery voltage- in order to save electricity and to enable near future vehicles, characterized by a high demand for power consumption, mainly because current mechanical operated systems - valves, air conditioning - are expected to be replaced by electrically powered systems.However, this transition towards a pure 42VDC network is going to be gradual, in a first step combining the current 14VDC -12VDC battery voltage -and the new 42VDC operating voltages, the so called "Dual Voltage architecture".Electrical and Electronic Distribution Systems (EEDS) are the keystone of energy optimisation strategies that will successfully fulfil the new requirements and the following electrical systems' aspects must be taken into consideration for a Dual Voltage power network: protection, switching, conversion, control signal management and distribution.Impact of the new network proposal must be analysed from the system architecture level right down to the component level -fuses, solid state devices, electromechanical relays, terminals and connectors, smart junction boxes, etc-. In this electrical system, the DC/DC converters arise as a new component for the automotive industry. It allows exchanging of energy flow between both power networks.The strategy of conversion -reversal and/or non reversal-together with the location of the conversion-from a full distributed conversion with many converters to centralized conversion with only one converter- is the basis that defines the top level of the electrical architecture
