a device used as part of an electronic device, which transforms electrical current from an AC line circuit to DC for use in electronic devices, and which can use either 110 volt or 220 volt AC line curent.
A power supply which achieves its output regulation by means of one or more active power handling devices which are alternately placed in the "off" or "on" states. It is more efficient than linear supplies which vary the conduction of power devices to achieve output regulation.
A type of power supply that uses a high frequency oscillator prior to the transformer so that a smaller, lighter transformer may be used. These power supplies are commonly used in synthesizer modules.
