Abstract

The present invention relates to an isolated power supply for a flyback circuit comprising a primary stage, a main output stage electrically isolated from the primary stage through an isolated transformer, and at least one secondary output stage, wherein the secondary output stage is isolated from the primary stage through a first capacitor (C31) and a second capacitor (C32), and the first capacitor (C31) and the second capacitor (C32) transfer an energy from the primary stage to the secondary output stage to be output.
