- power factor correction
Power factor correction (PFC) is a newer technology used in computer power supplies. PFC is applied to the circuits that include induction motors as a means of reducing the inductive component of the current and thereby reduce the losses in the supply. PFC has no effect on the operation of the motor itself. [Source: Adapted […]

- power line networking
Power line networking uses power line communications (PLC) to connect computers using existing power outlets in the home, essentially transforming every electrical outlet in the building into a network connection. Power line networking is one of the cheapest forms of home networking and has a low start-up cost and minimal IT workload. And despite using […]
- power management
Efficiently directing power to different components of a system. Power management is especially important for portable devices that rely on battery power. By reducing power to components that aren’t being used, a good power management system can double or triple the lifetime of a battery.
