	While working with various high quality electronic components, I have
noticed the utilization of switching power supplies.  I know these supplies
dissipate less heat and work by somehow increasing the input frequency,
but are these supplies considered new technology to replace humming          
transformers?  More importantly can anyone take the time to explain the theory
behind how these supplies actually work, and why they are used rather than    
the traditional transformer/diode bridge type?
