What is power in management?

Power management devices may be comprised of power distribution circuits and cables or voltage regulation to maintain a stable power supply reference. It may also relate to the way power supplies convert between different voltages and currents in a system or the conversion between AC and DC power. Often special signal switching and filtering is needed to implement the proper power management for an application. This may include feedback into a control loop to respond to the changing physical characteristics of the system – for example, angular velocity on a motor shaft or temperature in an oven.

Power management is critical in systems with batteries, including hybrid systems with battery and mains or another source of power like solar. Batteries can have their life expectancy significantly reduced by not staying within the discharge specification for the system or the charging profile for the battery technology employed. In many cases, systems behave differently as the battery power drops or if an alternative supply is selected. A system may have economy modes when battery power gets low, requiring charge level to be actively monitored.
