A power supply or UPS circuit can be a device that supplies electrical power to one or far more electrical loads. The term is most generally applied to devices that convert one form of electrical energy to an additional, though it could also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy. A regulated power source is one that controls the output voltage or present to a specific value; the controlled worth is held almost constant regardless of variations in either load electric current or the voltage supplied by the power supply’s power source.
A frequent power supply circuit typically includes in the following modul circuit:
