WebJun 10, 2024 · A new continuous conduction mode (CCM)/discontinuous conduction mode (DCM) hybrid-mode synchronous rectification (SR) flyback converter is proposed in this paper. This converter is realized by adding a combined switch in parallel with the auxiliary winding of the flyback transformer. The added switch is controlled to conduct a short … WebFlyback transformers may operate in both CCM and DCM modes, depending on the input voltage and load conditions. When designing a flyback transformer, the worst-case condition of maximum load at the …

Well anything can be stabilized if you lower the loop gain enough.... but in general yes a DCM flyback will be easier to compensate because it only has a single pole, even in voltage mode control. It should never have problems with conditional stability (unless it starts operating in continuous mode). WebThe drain to source (V DS) sensing control scheme allows UCC24612 to work with multiple topologies, such as Active Clamp Flyback, QR/DCM/CCM Flyback and LLC, et. Integrated features simplify the design effort, enabling UCC24612 to excel in a variety of applications and frequencies.
