Arrow Power Supply Requlation

Just one stupid question,


What is the meaning of regulated output, or Unregulated output in SMPS???


In a SMPS schematic I can see diodes and capacitors at the Transformer outputs, Those should do the regulation?? (as we know in Normal PSU)?

and the author of that supply wrote a NOTE on top of the ETD44 transformer.

Tempreture rises if supply in NOT regulated??


Any help about this?

Hi,
The regulation happens in the feed back section. It depends on the feedback gain. more the gain better the regulation.
The output diodes are capacitors are just rectifiers are filters.
