WebA continuous-conduction-mode (CCM) flyback converter is often used in medium power, isolated applications. CCM operation is characterized by lower peak switching currents, … WebMay 23, 2024 · A pure current mode control must either operate in DCM, or tolerate the instability that this chaotic behavior produces (increased input and output ripple current, subharmonic oscillation or noise). We CCM operation is desirable to reduce core losses, and somewhat reduce input/output capacitor ripple currents.
WebJun 10, 2024 · CCM becomes favorable for conditions where the input voltage is lower, while the current is higher ( over 6 ampere), designs … WebApr 26, 2024 · 運行方式：Iomax ccm 65％Iomax dcm. 這裡我們設計得是工作於CCM和DCM得電路，所以我們應該考慮兩個點： 1負載最大時點Iomax. 2 DCM與CCm的臨界點，這時得Io＝65％Iomax. 1臨界點. 1．1計算匝比與最大占空比

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.
