A typical application of a power supply is to convert utility AC voltage into regulated DC voltages required for electronic equipment. Nowadays in most power sources the energy flow is controlled with power semiconductors that are continuously switching on and off with high frequency. Such devices are referred to as switch mode power supplies or SMPS. The "switchers" offer greater efficiency compared with linear supplies because an ideal switch does not dissipate power. They are also smaller in size and lighter in weight due to the reduced size of passive components and lower heat generation.
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 (converter), AC to AC (AC power source, 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. This site is an information guide to power electronics and SMPS. Here you will find tutorials, tools, schematics, and other resources on all aspects of switching power supply design, information on other energy conversion sources, as well as basic electrical engineering and electronics reference.
