Can you tell me advantages and disadvantages between Switch Mode Power Supply and Linear Power Supply???

I forgot: linear regulators are better to use if you want a variable voltage output (like a lab supply) - SMPS's don't do variable voltage very well.
Hi IanP, do you mind to share with us the circuit? My appreciate.IanP said:FoxyRick wrote:I forgot: linear regulators are better to use if you want a variable voltage output (like a lab supply) - SMPS's don't do variable voltage very well.
This statement goes probably to far. I can show you a circuit (switchmode) which is adjustable from almost 0V dc to 100V dc with adjustable current limt from 0.1A to 25A..you will have difficulty in finding similar linear equivalent unless you would like to have a heater..
It is based on pretty unusual concept: regulation occurs on the negative line!

However, there is an article in January's Elektor about CUK convertors, and a project to build a variable CUK PSU with 0V to 100V, 5A output - quite impressive and well worth a look.
