Web(CCM operation) Figure 2.1: Diagram, schematic and basic waveforms for single ended forward converter 2.1 Key advantages over Flyback The Forward converter looks similar to the Flyback at first glance, but is fundamentally different in its operation and features. The main advantages over the Flyback are: 1. 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
WebAbstract. Controlling the feedback of off-line flyback converters has often perplexed power engineers because it involves the continuous conduction mode (CCM) and discontinuous conduction mode (DCM) small signal models. Due to the unique feedback compensation mode of the TL431 along with the optocouplers, tuning the feedback parameters still ... http://www.tc.faa.gov/its/worldpac/techrpt/ac65-13w.pdf
