WebNow that the topology (flyback) and control method (peak current mode control) have been decided upon, the next decision to be made is what the maximum duty cycle, Dmax, should be. The duty cycle is the ratio of on-time of Q1, Figure 2, to total period, orD=ton/ T. In a CCM flyback converter the maximum duty cycle will determine the turns WebDCM or on the edge of DCM/CCM operation, referred to as transition mode (TM) or critical conduction mode. Figure 2 shows the difference between the drain-to-source waveform of a DCM flyback that does not switch on the resonant valley and a TM flyback that does switch on the resonant valley. ranch marinated chicken wings
