A computer system needs various power supplies and the total cost of a computer is at present 1/3 power supplies. Figure right shows a power system employing one DC supply created from the mains and distributed individual power supplies for each sub-system.

The cable that is plugged into the aircraft that is waiting at the gate. In general terms the power conversion provides the following.

1 W < P < 10 MW: 10⁷ W range

The more Electric Aircraft initiative intelligently applies new, innovative electrically driven smart power sub-system technologies for aircraft secondary power which traditionally use hydraulic, pneumatic, mechanical and electrical components.
