WebMay 19, 2024 · Flyback converters can operate either in continuous-conduction mode (CCM) or discontinuous-conduction mode (DCM). For many low-power and low-current applications, though, the DCM flyback converter can provide a more compact and lower-cost option. Here is a step-by-step methodology to guide you through such a design. A flyback converter’s two operation modes seem very similar, but each has its own set of advantages and drawbacks. It is very important for designers to consider these advantages and drawbacks during the design process, as the selected operation mode has significant effects on the efficiency, transformer, … See more DCM offers higher efficiency than CCM, due to the lack of reverse recovery loss on the diode and a softer turn on of the MOSFET. However, if the duty cycle is too small, then the current that charges the primary inductor will … See more Regarding the transformer size, DCM requires a smaller inductance, which theoretically means it can use a smaller transformer. However, due to the incremented spikes … See more Because DCM charges and discharges the inductor completely, the primary current ripple is logically much greater than in CCM. This … See more Regarding regulation and stability of the system, a flyback in DCM is easier to compensate than a flyback in CCM. This is because the problematic right-hand plane zero (RHPZ) appears … See more
