Why are SMPS smaller than linear power supplies?
I understand when you switch at high frequency, the transformer,inductor and capacitor size reduces. Usually, there are 2 transformers in a smps. One at the AC input and one after switching.
How do they rectify the 60Hz using the first transformer. I am trying to understand this as the transformer is really small.
Is the freq upconverted some how?
