Power Supply Types | What are the Different Types of Power Supplies?
A linear power supply is, in many ways, the classic choice. It operates by taking the input voltage, and then, through a combination of transformers, diodes, and filters, provides a steady, direct current (DC) output. The process, however, can lead to some energy loss in the form of heat. Pros: Low noise and minimal ripple.

Chapter 7: Energy Storage Elements | GlobalSpec
The second distinguishing feature is that capacitances and inductances can absorb, store, and then release energy, making it possible for a circuit to have an electrical life of its own even in the absence of any sources. For obvious reasons, capacitances and inductances are also referred to as energy-storage elements.
Power Supply
Power Supplies. A power supply is, as its name implies, a source of power to an electronic circuit. Most electronic circuits operate from DC as they process AC or DC signals. The most common power supply is the one that gets its input from the standard AC wall outlet that supplies 120 volts at 60 Hz.
