dear friends,

can any body differentiate between SMPS (switch mode power supply) and DC regulated power supply.

Well, VA for VA, the SMPS will be smaller, Uncle, though a little more complex inside it. You'll find oscillators and other semicondictor stuff in the SMPS, where you won't find so much within a regulated supply.

A DC Reagulated Powe Supply consists of - may be, a transformer, a rectifier, filter & regulator.

Whereas an SMPS also contains a Capacitor Reservoir - which stores the energy.
