Project Description

i want projct for electronic power supply systmA power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (mechanical, chemical, solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.\r\nEvery power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from:\r\nElectrical energy transmission systems. Common examples of this include power supplies that convert AC line voltage to DC voltage.\r\nEnergy storage devices such as batteries and fuel cells.\r\nElectromechanical systems such as generators and alternators.\r\nSolar power.\r\nA power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. Examples of the latter case include the low voltage DC power supplies that are part of desktop computers and consumer electronics devices.\r\nCommonly specified power supply attributes include:\r\nThe amount of voltage and current it can supply to its load.\r\nHow stable its output voltage or current is under varying line and load conditions.\r\nHow long it can supply energy without refueling or recharging (applies to power supplies that employ portable energy sources).
