Abstract |
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 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. |
