WebA flyback operated in CCM reduces peak currents, RMS currents, and MOSFET turn-offloss. However the main disadvantage of a CCM flyback is the lower control loop bandwidth required to compensate for the presence of a right-halfplane zero (RHPZ). 2 Isolated Continuous Conduction Mode Flyback Using the TPS55340 SLVA559– … WebAt the boundary between DCM/CCM (sometimes called BCM point, or transition-mode (TM) or critical conduction mode (CrM)), the duty cycle will depend on the input voltage and the reflected output voltage - as evs said, volt-sec balance must be maintained: Dccm = Vrefl / ( Vin + Vrefl) Vrefl = Np/Ns * (Vo + Vrect)
