In the future cars will have a 42 V electrical system and operate in the “idle-stop” mode. Both developments present opportunities for innovative power electronic applications. Idle-stop operation requires a supply of electric power to maintain Heat Ventilation Air Conditioning (HVAC) and other ancillary functions when the engine is off, motivating the development of new generation and conversion technology. Electrification of functions such as engine valve operation, transmission clutches and water pumps also present cost, control and reliability challenges. The 42 V architecture is described and some of the resulting opportunities and challenges are discussed.
