Power

Abstract

The quality of power delivered to circuits can profoundly influence the proper operation of those circuits. Power supplies must deliver a required output voltage and current; voltage ripple is another important metric. An understanding of power supply design helps us to choose the proper power supply. AC-to-DC supplies convert alternating current to direct current. Power converters transform DC to DC. Batteries have several important characteristics that influence system design. Many embedded computers use power management hardware and software to manage their power consumption. A simple linear regulated power supply is used as an example.
