WebDiscontinuous Flyback Converter Fundamentals Figure 2 shows typical current waveforms of a DCM flyback converter in operation. To simplify circuit analysis, we can convert the flyback circuit to a basic buck-boost converter configuration. The conversion can be done in two steps: Step one: converting all outputs into a single output. Let VO = WebThis means there are two feedback loops: one that monitors the output voltage, and a faster loop that monitors the current through the inductor. Whether it is a forward, buck, boost or a flyback topology, the current-mode controller will require monitoring of both loops for standard operation.
