Before proceeding with the design process, we need to confirm the fundamentals of the isolated flyback converter.
As shown in the following outline, we will discuss switching AC-DC conversions, the characteristics of a flyback converter, its operation and snubber, and continuous and discontinuous modes. A solid understanding of these concepts is a prerequisite for the design process.
