Design Method of PWM AC/DC Flyback Converters

Want are Isolated Flyhback Convertors?

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.
