power supply question

[Moleculo]

I suppose I should know this, but can someone jog my memory as to the difference between a switched power supply and otherwise?





thx,

the conventional pwr supply has the big heavy transformer in it, and gives of trememdous gobs of heat. the switching supply basically has a clock timer in it that "switches " ac on and off and a desired rate or set point early ones were very noisy in an rf sense, most of the newer ones are pretty well filtered when designed for communications. they stil generate heat but don't even come close to the weight of a conventional supply. your'e computer has a switching supply in it. hope this helps, even though it's pretty simple explanation. 73
