The electric energy is not normally used in the form in which it was produced or distributed. Practically all electronic systems require some form of energy conversion. A device that transfers electric energy from a given source to a given load using electronic circuits is referred to as power supply. Of course, it does not really supply power, it just converts it, so "converter" is a more accurate term for such a device. A typical application of a DC power supply unit (PSU) is to convert utility AC voltage into regulated DC voltages required for electronic equipment. Original PSUs were linear. Nowadays most of them are of SMPS type. Do you wonder what is it? The units in which the energy flow is controlled with semiconductors that are continuously switching on and off with high frequency are referred to as switch mode power supplies or SMPS. In general, SMPS can be classified into four types according to the form of input and output voltages: AC to DC (also called off-line DC power supply), DC to DC (voltage or current converter), AC to AC (frequency changer or cycloconverter), and DC to AC (inverter). The field of engineering that deals with the design and analysis of power conversion circuits and devices is called power electronics, although power supply design is a true cross-disciplinary task. It involves the circuit, magnetics, thermal management, control and compliance issues. This site is the power electronics information guide. Here you will find a tutorial, tools, reviews, schematics, and other free online resources on all aspects of switching power supply design and selection, information on other energy conversion devices, as well as basic electrical engineering reference and electronic formulas. |
